• All hell broke loose this week after a security flaw in 70% of the world's websites was made public.
• It was supposed to be kept under wraps as a fix was deployed, but one researcher jumped the gun.
• Chainguard CEO Dan Lorenc told POLITICO why he decided to go public.

The exposure was immense, with AI multiplying the risks — and yet time-tested global cybersecurity procedures appeared to be functioning. Then suddenly, it all broke down.

The decision by a cybersecurity company on Wednesday to prematurely release information about a flaw in the popular PHP computer programming language left much of the web exposed to hackers, triggering a panic that brought to life months of warnings of how the AI-powered era could cause widespread damage.

The flaws in PHP, discovered using AI tools through a monthslong process coordinated by OpenAI, caused cyber agencies across Europe, the US, the UK, Australia and Canada to post urgent warnings Wednesday. Numerous governments took websites offline as a precaution.

While no major hacking damage was immediately apparent, the way the incident unfolded over 72 hours showed how easily cybersecurity processes can break down and the outsized consequences of cyber risks in the AI era.

The man who set off the chain reaction with the early release — Chainguard's CEO Dan Lorenc — quickly apologized in a LinkedIn post. But on Thursday, in an interview with POLITICO, Lorenc said he'd shared the information ahead of time because the flaw was already being exploited. Though others disputed that, Lorenc said he believed he'd seen enough evidence to invalidate an embargo set up to allow time to find a fix for the flaws.

While he disputed that his actions would have caused problems for other defenders, Lorenc said that the evidential threshold in these coordinated cyber defense systems is a "grey area."

The revelation of the PHP flaw brings out into the open what cyber officials have been bracing for since the arrival of the most powerful tools of artificial intelligence, which not only can be used to discover vulnerabilities but also to exploit them at scale.

The cybersecurity world's long-established protocols helped prevent disaster scenarios in which hackers would have successfully exploited the vulnerabilities to take control of numerous websites and access their data. But the scale and end-of-days potential of AI-driven cyber risks are now visible for the world to see.

This "is what happens when AI turns up a flaw that's been hiding for years," said Eylam Milner, cofounder and chief technology officer at cybersecurity startup Echo. The vulnerabilities, he added, are "about as serious as it gets for the web."

Origin story

Understanding how this week's emergency unfolded offers a glimpse at how companies and authorities are working to stave off attacks — and how much risk they face going forward.

The origins of the incident can be traced back as far as April, when leading frontier AI firm Anthropic unveiled Mythos, leading some in the cybersecurity world to worry that systems would quickly be overrun by advanced artificial intelligence, with potential for catastrophic events to ensue.

But while researchers did find more flaws in computer systems in the months after Anthropic and other AI firms like OpenAI released those models, they had little impact in the real world. Even the Hugging Face incident, a widely discussed hack that saw OpenAI's autonomous AI agents go rogue during an internal security evaluation, related more to the level of control AI companies exert over their models than their power to break into systems worldwide.

That changed this week after researchers unveiled the vulnerability in PHP, a coding language estimated to be integrated into some 70% of the web.

The process by which information about flaws is released among cybersecurity officials and affiliated companies is crucial. Through a long-standing practice known as coordinated disclosure, researchers and companies that identify flaws can find a fix and share it confidentially with agencies and others before releasing it to the public, meaning they don't hand malicious hackers the gift of a hole without a fix.

In the case of the PHP flaw, that process worked well, but not perfectly. Information about the bugs started to circulate ahead of the planned release time. Then, according to the PHP Foundation, Chainguard "unilaterally broke the embargo," which "disregarded weeks of work by many parties toward a coordinated disclosure." PHP Foundation executive director Elizabeth Barron told POLITICO by email that while it was "disappointed" with Chainguard, it hopes to "rebuild trust with them in the future to ensure we can continue to collaborate effectively."

After the leak — which meant information about the bugs was in the open before the fix was ready — confusion quickly ensued, with government bodies and private companies choosing to temporarily shut down their websites rather than risk potentially damaging breaches to their data and the sites themselves.

Early Thursday, Matthew Prince, the CEO of Cloudflare, an internet services company widely used by websites to block cyberattacks, which gives it a high level of visibility into what hackers are doing, said in a post on X that it had seen "millions" of attempts to exploit the flaw.

Cloudflare saw thousands in the 10 hours before the flaw was publicly announced, then tens of thousands in the 45 minutes after the announcement, hundreds of thousands within two hours, and now millions, Prince said.

Amazon's cloud division also said the flaw is "now being broadly exploited in the wild."

One senior US government cyber official said that federal authorities have been overwhelmed — and not just by PHP. The same day the world was racing to address PHP, they were also dealing with bugs in node.js, a widely used JavaScript framework, Fortinet, GitHub and Oracle.

"The fire department is fighting multiple fires at once," the official said, adding: "The good news is they're all one-story structures on fire, which the fire department deals with all day, every day."

More to come

Dauntingly, OpenAI said there's more on the way. "These bugs are among several significant vulnerabilities we've already found and are working to fix, and we expect similar findings to increase sharply in the coming months," the company said Wednesday in a statement.

Matthijs van Amelsfort, head of the Dutch cybersecurity agency, said in an interview that the job of keeping computer systems safe has been transformed by the advancement of AI. "As soon as the frontier models came out, that's exactly what we said: This will be the trend," he said. "And actually that's happening now."

Thomas Caspers, vice president of Germany's cyber agency BSI, concurred: "We expect that [to be] happening more and more during the coming months."

AI also ramps up the risks once the flaws are out in the open. Cyber agencies' recommendation that organizations take their websites offline was "really a drastic measure," Caspers said. "We wouldn't have done that a few years ago or so." But because AI has made it quicker and easier to exploit flaws, "we had to do that," he said.

At the same time, the use of advanced AI to detect the flaws may create a new level of protection against malicious hackers looking to take advantage of them. Caspers said that though his German agency has also seen attacks, it has not seen any successful use of the flaw by hackers.

"It seems a little bit more complicated than expected to exploit," he said.

Despite the fact that AI offers a new way to discover flaws, the work involved in keeping systems protected is more quotidian, with cyber agencies urging organizations to install the fix shared by the PHP Foundation, in a process known as patching.

"There are three things that you have to do right now," said van Amelsfort from the Dutch agency. "And that's patch, patch, and patch."

• Jen Eaves' mother is 79 and lost more than $3,000 to online scams.
• Eaves now monitors her mother's finances and says that was a hard conversation.
• Digital caregiving is an important part of supporting aging parents, she says.

This as-told-to essay is based on a conversation with Jen Eaves, Digital Caregiving & Elder Fraud Advocate at Aura. It has been edited for length and clarity.

It's an odd shift in dynamic when you start caring for the people who always cared for you. My mother is 79, and lives with my brother, who handles most of her day-to-day physical care. I'm the one who handles the administrative side of care, like scheduling doctor appointments and keeping her safe online.

About six years ago, my mom had a stroke, and while she recovered fairly well, she wasn't the same cognitively as she had been before. Around that time, I began noticing her falling for scams online.

Once, she ordered a cure for diabetes, which she has. The product was supposedly being sold by a famous TV doctor. When she showed me the video ad, I could see it was badly done AI, with the supposed doctor's lips not matching his words.

There have been other scams and pitfalls, too: online orders that never arrive, or even a legitimate credit card that my mom opened without realizing what she was doing. All in all, she's lost about $3,000 to scams, though I've been able to recover most of it through her bank.

I've realized that I need to take a more proactive approach to digital caregiving to protect my mom's finances. Here's what I'm doing.

Approaching from a place of help and dignity

After my brother and I had taken my mom's keys away, her phone became her connection to the world. I wanted to respect that. While some people have to restrict their older parents' access to phones, that didn't feel right in my case.

It was critical to me that my mom kept her dignity and as much independence as possible. At the same time, I saw there was an emotional side to falling for a scam: she would feel frustrated and confused when it happened, and I wanted to spare her those negative emotions.

I never want my mom to feel like I'm parenting her. Instead, I pointed out the patterns I was seeing and emphasized I'm here to help if she's willing to let me be involved. The choice, ultimately, is hers. This would be a lot harder if she wasn't willing.

Talk about scams

My mom wasn't particularly tech savvy, even before her stroke. I've had to educate her about what scams look like. When she shared the famous doctor video, I pointed out the aspects that seemed AI-generated to me. I remind her that if it sounds too good to be true, it probably is. I emphasize that urgency is a big sign of a scam. The bank, I tell her, is never going to call you.

Once, she had a scam caller claiming to be Apple support. They asked for her Apple ID and password, which would have given them access to pretty much everything she has online.

Because of our conversations, my mom hesitated. She patched me into the call and asked the scammer to explain the situation to me. I was very proud that she recognized the scam and knew to ask me for help.

I monitor my mom's accounts

I worked in cybersecurity at Aura, which offers a lot of great products for keeping kids safe online. But my experience with my mom made me realize we were missing a whole vulnerable population: older adults.

I helped develop Trusted Family Access, which allows family members like me to see alerts from their loved ones' accounts, with permission. This gives me peace of mind that I can catch any issues quickly. It's also made other aspects of caregiving easier, like handling medical appointments, because I have access to all my mom's information in one place.

When my mom was scammed, it felt like I was a victim too. I spent hours calling her bank and credit cards to get her money back. If she were to lose her savings, it would impact the whole family. I'm grateful we've found a solution that empowers both of us to keep her finances safe.

• Everyone complains about AI-generated junk.
• But decades of sloppy human-written software may be a much bigger problem.
• This week's "Black October" freakout was caused by human slop, not AI.

The internet has a slop problem. And for once, we can't blame AI.

Most of us spend hours online every day without thinking much about the software holding everything together. We assume somebody, somewhere, has made sure it all works properly.

So it probably came as a shock this week to discover just how vulnerable some of that software is.

The cybersecurity freakout dubbed "Black October" has inspired warnings about AI-powered hackers, digital catastrophe, and even advice to stockpile cash and canned food.

At first glance, AI looks like the villain. But this is largely a human-made mess.

Here's the problem.

The internet runs on decades of software, some of it containing security weaknesses that have been overlooked, tolerated, or simply left unfixed.

For years, that was a manageable gamble. Fixing software takes time and money. Exploiting obscure weaknesses often required considerable expertise. Companies could convince themselves that the risk wasn't worth worrying about.

AI is changing that calculation. Someone who once needed years of training to hunt for weaknesses can now get help from an AI model. These tools can also examine software at speeds that humans can't match.

Suddenly, all those problems we've been ignoring look more urgent.

"Over the last 10 years the risk acceptance process has morphed from a way to accept risks to enable the business, to a way to justify never fixing security issues," Joel de la Garza and Zane Lackey, partners at a16z, wrote on Friday.

That's quite an indictment. The result is a recent surge in published vulnerabilities.

This looks like AI is creating new security problems. But it's actually AI exposing weaknesses that humans left behind.

Slop irony

The irony is delicious. We've spent the past couple of years complaining about "AI slop." Turns out human slop can be pretty consequential, too.

"The funny thing is everyone was saying AI slop code will cause a cyber crisis but it's actually all the old human slop causing it and the AI is just cleaning it up," software engineer Ben Kaufman wrote on X on Thursday.

"Humans have been the ones writing and reviewing each other's code for decades," tech founder Anant Jain wrote on X. "If we're being intellectually honest and holding ourselves to the same bar we hold AI to, we'd have to admit that we haven't been all that good at it either."

Humans are sloppy

Anyone who's worked with other humans for a decade or two knows exactly how this happens.

It's Friday afternoon. You've almost finished a project. You could spend another few hours making it perfect, or declare it 90% done and head off to that dinner party. We've all been there.

AI agents don't have dinner parties. They don't get tired on Friday afternoons. They can keep searching, testing, and trying again. That persistence is now colliding with an internet built by busy, imperfect humans who often settled for "good enough for now."

A tragedy of the commons

There's another wrinkle here, though, and it's an important one.

Much of the software underpinning the internet is freely available for anyone to use. Some of it is maintained by volunteers or small groups of experts, even as enormous technology companies depend on it.

In 2020, the cartoonist Randall Munroe captured this absurdity in an xkcd comic. Modern digital infrastructure still rests precariously on tiny foundations.

It's funny because it's uncomfortably close to reality. Take the specific PHP problems from this week. These flaws have existed for years, and the PHP Foundation acknowledges that limited resources and disagreements over fixes contributed to delays in fixing them.

Tom Occhino, chief product officer at Vercel, brought up Munroe's cartoon during my recent interview with him.

He explained that AI is finding weaknesses even in software that the industry has treated as dependable for decades.

This is partly a version of the tragedy of the commons: Everyone benefits from a shared resource, but no one has sufficient incentive to take responsibility for maintaining it.

And let's be clear: The volunteers keeping essential software running aren't the villains here. The companies benefiting from their work have a much greater responsibility.

Occhino thinks AI could help solve the problem it is exposing.

He described an idea being discussed at Vercel: Create a foundation or coalition that funds efforts to identify vulnerable software and replace it with safer alternatives.

"We need a consortium. We need a coalition," he told me.

He suggested companies could contribute computing resources and AI tools to the effort. Nothing has been formally announced, but the idea is compelling.

Indeed, OpenAI's Patch the Planet effort is an example of what's possible.

Rather than simply using AI to create more software, the industry could use it to repair what already exists.

Occhino put it nicely: Companies need to spend less time chasing new ideas and more time asking how to make existing systems "just work really, really well."

That's a better response than panicking about the imminent collapse of the internet.

AI didn't create decades of neglected software. We did. Perhaps it's time to clean up our own slop.

• Mark Cuban compared swarms of AI agents to cockroaches finding ways into systems.
• Cuban said agents can launch brute-force attacks at scale without inventing new hacks.
• Cuban said defenders can also "spray" their systems with AI, which makes defenses more accessible.

Mark Cuban has pest-control tips for the AI age.

Speaking at a Reuters NEXT Newsmaker event on Friday, the entrepreneur and billionaire investor compared the threat posed by swarms of AI agents to cockroaches finding their way into a freshly treated house.

"When I go talk to cybersecurity experts, I ask them all the time. I'm like, when we hear about these hacks and breakthroughs and, you know, different problems, do these AIs invent something new?" Cuban said.

"No, they didn't invent something new," Cuban added. "But they're able to do something in mass volume that it's all brute force hacks."

Cuban compared the challenge to keeping cockroaches out of a house.

"It's like the cockroach theory, where if somebody can create enough agents, it'll find a way to get in, and then it just exploits that. But the good news is you can spray your systems with just as much AI, and I think there's gonna be more effort from the good guys trying to stop the bad guys," Cuban said. "I'm not a doomer at all."

The AI industry is already creating its own team of exterminators to contain risks.

OpenAI safety roles on LinkedIn jumped by 91% over the past year, spanning work such as system testing, technical research, and governance.

The risks have also surfaced during testing. Anthropic said that three Claude models accessed organizations’ live systems without permission after a third-party testing environment was misconfigured. The company subsequently introduced real-time classifiers to detect and block attempts to escape testing environments.

Cuban said AI could make malicious activity more accessible, but the same techniques could also strengthen defenses.

"There will be scenarios where bad stuff happens, but we've always had hacks," said Cuban. "And if it's brute force on that side with the bad guys, you can also use brute force with the good guys."

• PHP, the open-source computer programming language, had two major vulnerabilities exposed.
• Yonaton Keller woke on Wednesday to panicked messages about the two PHP vulnerabilities.
• He shares three steps you can take to protect your website.

This as-told-to essay is based on a conversation with Yonaton Keller, a 46-year-old product manager at Zafran Security, based in Tel Aviv. His words have been edited for length and clarity.

When I woke up at 6:30 a.m. on Wednesday, I had multiple messages from around 4:45 a.m. alerting me that two vulnerabilities in the PHP programming language had been disclosed.

I immediately understood that this was a very serious situation.

Websites run different versions of PHP, and it's estimated that around 70% of websites worldwide use it. This isn't the first time PHP vulnerabilities have been found, but these ones require essentially no authentication on the attacker's part.

It's a very tricky situation. If it were a year and a half ago, nobody would have really responded to this so urgently. But this might be one of the first major incidents of its kind in this AI era, and the cycle of how attackers operate and how we typically respond is broken.

AI enhances detection and response times, but it also means that any limited-technical person could exploit these vulnerabilities within minutes.

My team was very concerned and had to act fast

I'm based in Israel, so when it was 6:30 a.m., my time, it was the middle of the night in the US. This time gap worked in our team's favor, as we had time to figure out what was going on before our customers woke up.

PHP is an open-source computer programming language used to create websites and web applications. It's such a widely used programming language that we immediately understood that every one of our customers, which includes major corporations and businesses, would likely be affected by this.

With bugs or critical flaws in the infrastructure, like the two that were found in PHP, exploitation is actually quite easy, especially if you use AI agents. That was the first thing we understood: even completely unskilled attackers can use these vulnerabilities to take down sites.

The PHP Foundation said it would disclose the details of the vulnerabilities and release a fix for newer versions of the language around 5 p.m. Israel time. But some details had already been informally disclosed on an online forum. The post was deleted minutes afterward, but screenshots spread around the internet quite quickly in unofficial forums.

So, my team and I dropped everything else and spent all day on Wednesday gathering informal information to see whether we could mitigate the risk of exploitation before an official fix was released.

How to tell if you're at risk

The first step people can take to figure out if they're impacted is to look at their websites and web applications, and try to understand where PHP is involved. You can also assume that most, if not all, of them will use PHP in some way, unless you have very basic HTML-based pages.

The second step would be to look at what vulnerability scanners online are telling you. Tenable, Qualys, and Rapid7 are usually the big three for releasing detection rules and actually detecting the vulnerability. In this case, these vulnerabilities have caused such widespread panic worldwide that they were quick to respond. This is also a way to understand the exact vulnerabilities in your internet-facing assets.

After taking these steps, immediately look online to upgrade your website to the current PHP version. It's quite easy to upgrade that, and it's free. There are some technical steps to do after the fix, so you might need a tech guy to implement them. If you don't update your PHP version, the impact on your business and website can be very, very serious.

Some people are also fully taking their sites offline, and I think that can be the right call if you have evidence that you are being targeted. However, 70% of the internet can't and shouldn't be taken offline just because those sites have some vulnerabilities. It's an emergency step to take if you have evidence of potential exploitation, but it can't be a step taken by everyone.

This was not just about attackers disrupting your website or web application; it was about them taking control of your server, stealing sensitive documents, moving inside your network, and then carrying out malicious operations, such as deploying ransomware or other actions they intended.

The situation has calmed down, but my cybersecurity team is still very concerned

Things have calmed down a bit since Wednesday, but we're still very, very concerned. Patching 70% of worldwide websites doesn't take a minute or two.

Hours after the fix was disclosed by the PHP Foundation, there were already tons of exploitation attempts popping up online. Attackers are getting quicker. I think that in this AI era, when in a matter of minutes, many attackers can attack, you don't have the time you used to.

The whole traditional process of scoping the attack surface, establishing a remediation plan, then calling a guy who's going to be responsible for this remediation plan, et cetera, is broken.

For a long period of time, organizations were investing a lot in what we call post-compromise scenarios. I think the AI era of cybersecurity will involve a lot more security investments in the pre-compromise realm, so defenses can be pre-built and ready for attacks in situations like this.

The Greek Ministry of Defence plans to merge or close dozens of military units and facilities, while simultaneously establishing new commands for unmanned aerial vehicles (UAVs), space operations, and cyber warfare. This restructuring is estimated by authorities to save 530 million euros over five years. On Tuesday, Defence Minister Nikos Dendias presented the third phase […]

If you're reading this, then the internet still works. But that's something that we shouldn't necessarily take for granted after this week's global cybersecurity meltdown.

"Think of it this way: someone discovered that millions of buildings in the country have the same broken lock, and now everyone knows how to open it," writes Matt Shumer in a lengthy post on X about the situation. "The lock maker has sent out a fix, but every building owner has to install it themselves, and many haven't yet."

That massive vulnerability was identified with the help of AI, but the growing capabilities of AI-powered hackers mean that vulnerabilities can be exploited much more rapidly too.

This is the world we live in now. In August, more than 100 tech companies signed a letter warning about exactly this possibility. On Thursday, one of Anthropic's top information security officers wrote that cybersecurity threats "are going to get a lot worse before they get better." Major banks are rushing to secure themselves after reports of autonomous agents operating inside accounts (though many of them may have been authorized by account holders).

This is unlikely to be the last incident like this. Cybersecurity firm CrowdStrike says it saw twice as many "agentic intrusions" (hacking done by an autonomous or semiautonomous AI) in August as in July, and then the number doubled again in September.

Scary stuff, for sure. As is usually the case, however, prevention is better than panic.

Shumer's post contains many helpful suggestions for better online security—it is particularly important to secure your email accounts, since that is the gateway to so much of what we do online. Here's a 15-step plan to stay more digitally secure in the AI age. (And if you're really worried about everything falling to bits, Reason's got you covered there too.) If your devices and browsers have updates available, install them. And for the love of digital gods, don't click on random links in strange emails!

The man who (maybe) saved the internet? There is an old XKCD webcomic—and I'm dating myself as a very specific type of millennial by even referencing that—that seems to perfectly sum up what happened this week. Here it is:

Here's the craziest part: That's basically true! Except the one random person lives in Czechia instead of Nebraska. His name is Ondřej Surý, and The Atlantic's Charlie Warzel found him:

Surý, who lives in Czechia, does not work for the PHP Foundation. But alongside his day job as director of domain-name-system engineering at the nonprofit Internet Systems Consortium, in a volunteer capacity, he maintains and helps automate patches for the coding language. His work, with that of just a handful of others, has allowed countless websites and organizations to fix these vulnerabilities quickly. Over the past 48 hours, he's become arguably the unsung hero of the entire internet—despite the fact that the only compensation he receives is from modest donations. "Ondřej will save the internet today," a user in the PHP Subreddit wrote.

In the war between AI hackers and AI defenders, it's still humans who are the heroes. At least for now.

Art of the steal. Yesterday, in this space, I detailed how voters are fed up with the Trump administration's seemingly endless stream of corruption. But it's been a whole 24 hours, which means there is yet another scandal in the news—thanks to a Vanity Fair article about President Donald Trump's son-in-law Jared Kushner.

The article is an excerpt from a forthcoming book. In it, author Matthew Cole claims that Dutch investigators gained access to Kushner's phone with the help of Russian hackers. The evidence from the phone and other sources shows that Kushner has been taking money from the governments of Saudi Arabia and the United Arab Emirates to "push their agenda with Trump."

Kushner says the article's claims are "outrageous and categorically false."

But wait, there's yet another corruption story. The Justice Department is reportedly probing whether Trump ally Corey Lewandowski profited from his role as a top adviser at the Department of Homeland Security (DHS). The Washington Post reports that the investigation is based on a referral from the DHS inspector general and is focused on "contracting fraud."

It may or may not be connected to other allegations that surfaced in September, when The Wall Street Journal reported that Lewandowski approached officials in Qatar and the UAE about being hired to help with "visa issues" and other matters.

In both matters, Lewandowski has denied the allegations. He's no longer working for the department, having been fired earlier this year amid a messy scandal involving then–DHS Secretary Kristi Noem, who was also canned.

Scenes from Virginia: Federal prosecutors indicted state Sen. L. Louise Lucas (D–Portsmouth), one of the most powerful Democrats in Virginia, on charges of racketeering and money laundering in connection with illegal marijuana sales. (Don't get me started on how dumb it is that recreational marijuana use has been legal here since 2021, but commercial sales are still forbidden. If it's legal to use something, it should be legal to sell it!)

Lucas pushed the failed Virginia redistricting effort and has been an outspoken critic of Trump. She plans to fight the charges. Virginia Gov. Abigail Spanberger, also a Democrat, said in a statement that the timing of the indictment, just days before the midterm elections, "further erodes the trust the American people deserve to have in the Department of Justice."

CISA told organizations to take unpatched PHP systems offline as some Wikipedia and 4chan services went down

• Nick Woodhead said he went 48 hours without sleep while helping patch a major website vulnerability.
• The CTO said that with security problems piling up, October feels like "the month of hell" for tech.
• Because AI makes it easier to find and exploit security gaps, Woodhead expects more disruption.

This is an as-told-to essay based on a conversation with Nick Woodhead, founder of the AI company GPTree and chief technology officer at Rothco and Compubox. He spoke with Business Insider on Thursday to share how he's responded to vulnerabilities in the PHP programming language that could affect the majority of the world's websites. The following has been edited for brevity and clarity.

It's always a nightmare when these things happen. Since Tuesday evening, I haven't slept. It's coming close to 48 hours working on this. I'm a CTO, but I also run an agency for multiple clients and have my own company with my own product. So, balancing my time to get everything updated — it's just been exhausting.

About 70% of the internet runs on a programming language called PHP. I'm actively involved within the PHP community itself, so I did get a warning on Tuesday evening regarding the vulnerability and the fact that it was already being addressed by the PHP team. That gave me a head start.

I have some teams offshore, so I was able to jump on that with them.

It's not just applying the patches. It's making sure that nothing was already exposed. We already had infrastructure in place to easily deploy patches, but it still requires a good amount of manual involvement.

I knew that as soon as I walked into the office on Wednesday, I'd have to have my teams jump on this. They were already waiting for the patches to be released.

People are willing to help

One of the biggest headaches, especially on the client side, is that we have a lot of legacy systems, which are running on older versions of PHP that are no longer supported, and official patches are not going to be produced. For those, we ultimately had to come up with other plans. For example, taking sites temporarily offline or moving them behind VPNs.

Eventually, because it's an open-source community, those patches have already been backported, or implemented, by the community. So now we're shuffling back to some of those older systems to get them patched.

That's one of the nice things about PHP. There's such a vast community of people all willing to roll up their sleeves and jump in and help.

Even though I've been in leadership for the last 10 years, I've never taken my hand off the pulse in terms of being connected with the code and the infrastructure. So, I've been hands-on with the development and infrastructure teams to help make sure these issues are resolved. We've been reviewing logs and looking for any potential signatures of a breach that this vulnerability exposed.

The month of hell

It's also meant keeping up to speed with the latest news that's coming out and what other people are finding. We're in a position now where we feel comfortable and safe, but there are new vulnerabilities in the coding tool Node.js. We have some Node services, so now we're looking at how that potentially affects us. October just seems like the month of hell from a technology perspective.

I don't think there is an end in sight with the advancements in AI. For all the positives we get from it, there are a whole bunch of negatives, and this is a perfect example.

OpenAI has already stated that they found many more of these types of vulnerabilities that, thankfully, haven't been leaked. Over the coming months, they are either going to be patches or this information is going to get leaked in the same way and cause the same kind of panic.

I don't think we're at the end of the road yet. There's going to be a lot more to come.

• The message from Cloudflare's Stephanie Cohen and Vercel's Tom Occhino: Don't panic!!!
• Do we need everything connected to the internet? Paper bank statements work well.

A few weeks ago, I heard a strange story about a friend who works at one of the Big Tech companies in Silicon Valley.

She'd recently ripped out the connected devices in her home, ordered paper bank statements, and stocked up on canned goods in her basement.

Now, she's a very sane, experienced person, and quite senior at one of the largest internet companies on earth. Why was she disconnecting so much? Just to be sure, my family ordered paper bank statements, too. It was still a head-scratcher, though.

Fast forward to this week, and her actions look a little less crazy.

AI models have exposed serious security weaknesses in software used by roughly 70% of websites. Meanwhile, US banks are finding AI agents inside customer accounts, including some that appear to be acting without their owners' instructions, Axios reported.

'Black October'

The digerati have now entered full freakout mode. Much of the internet meltdown is happening on, well, the internet, my colleague Alice Tecotzky noted.

On X and Reddit, warnings of a looming “Black October” spiraled into visions of AI grinding civilization to a halt. One lengthy post on X warned of a potential “global cyberattack/AI swarm” and offered a survival checklist: Stockpile cash in small bills, print out your neighbors' phone numbers, download maps, buy a hand-crank radio, and stash a gallon of water per person per day.

Oh, and don't forget the manual can opener. You don't want to survive the AI apocalypse only to be defeated by a tin of beans.

Nikita Bier, a prominent app developer and former head of product at X, best captured the mood.

"It's time to turn off the internet," he posted Wednesday night.

A Cloudflare exec says it's 'a little bit scary'

If you're reading this, you haven't done that yet. But should we really be worried?

I put that question to Stephanie Cohen, chief strategy officer at Cloudflare, which helps protect about 20% of the internet.

"The world is a little bit scary right now," she told me on the side of Cloudflare's annual conference in San Francisco this week.

Here's the problem. The internet is built on decades of software, much of it riddled with security holes.

Some of these weaknesses have been known for years. However, fixing them takes time and money, and hackers often lacked the skills to exploit them anyway. So they were left alone.

AI changes that calculation dramatically. Someone who previously needed years of training to break into a computer system can now get help from an AI model. And these tools can search for weaknesses at a speed humans simply can't match.

The result: The number of newly published software vulnerabilities (Common Vulnerabilities and Exposures in industry lingo) has exploded.

Now, there's a frantic race between people trying to break into systems and those trying to protect them.

Don't panic about AI

Cohen's message, though, was surprisingly reassuring.

AI helps the good guys find and fix these problems. Cloudflare, for instance, released protections for the latest vulnerability to customers, including those using its free service.

And there's a bigger effort underway.

OpenAI has launched an initiative called Patch the Planet, working with Cloudflare and other security professionals to use AI to find weaknesses in widely used software and help repair them.

Tom Occhino, chief product officer at Vercel, told me recently that his company has been talking with partners about launching a nonprofit that would fund a swarm of good AI agents that go out on the internet to find and fix software flaws.

Amazon is joining the fight, too. Its new Continuum service, available Thursday, uses AI agents to find security holes and propose fixes. Amazon said that people maintaining freely available software can use it to help protect the wider internet.

Humans may still have to check and approve these repairs, but the prospect of AI helping clean up decades of neglected software is encouraging.

The irony of this is not lost on some in the industry.

"The funny thing is everyone was saying AI slop code will cause a cyber crisis but it's actually all the old human slop causing it and the AI is just cleaning it up," software engineer Ben Kaufman wrote on X on Thursday.

Either way, Cloudflare's Cohen thinks these AI-inspired freakouts will push the industry to do better — by exposing issues and adding urgency to get them patched.

"We may end up in a world where actually we've become significantly more secure at the end," she said.

The trouble is getting there.

A fundamental question about the internet

When I ran into Occhino recently at a Vercel conference in San Francisco, he described a world in which software that everyone assumed was safe suddenly looks vulnerable because increasingly capable AI models are scrutinizing the basic systems that underpin the internet.

That led to a more fundamental discussion between us: Why did we connect so many things to the internet in the first place?

For years, the technology industry has raced to put everything online. Thermostats. Refrigerators. Doorbells. Cars. Bank accounts.

We assumed that connecting something to the internet automatically made it better.

Perhaps we should reconsider.

Before the internet

I remember the world before the internet. It worked pretty well. We managed to buy groceries, pay bills, heat our homes, and generally get through the day without every appliance talking to a computer somewhere.

That doesn't mean abandoning online banking or throwing your smartphone into the sea.

Occhino, for one, isn't particularly worried about hackers wiping out his bank account. Modern banks have sophisticated protections, and he recommends everyone turn on additional login security.

Maybe the cybersecurity crowd, which spends its life immersed in online threats, is missing something obvious.

Not everything needs to be connected.

Occhino put it neatly: "There's certain things that don't make sense to be on the internet in the first place."

Perhaps that's the lesson from this week's panic. We don't need to turn off the internet.

We just need to remember where the off switch is.

• Execs and analysts are sounding the alarm after AI discovered a flaw affecting the majority of the internet.
• Experts say critical systems, from energy and water to healthcare, may be especially exposed.
• Here's what smart people are saying about the biggest threats to the internet at the moment.

It's been a nightmarish week for cybersecurity.

AI helped discover two "critical" flaws in the infrastructure of PHP, a programming language that up to 70% of websites use, prompting companies to race to roll out a fix or risk being hacked.

The incident has illustrated how AI is creating a new level of risk for businesses and consumers online, in a week when multiple other cyber threats caused headaches for security workers.

Here's what executives and analysts are saying about the biggest cyber threat of the moment — and how AI could make things even worse.

• Cybersecurity researchers say the PHP vulnerability has repercussions for normal people, too.
• Even if you don't own a website, hackers could use the vulnerability to steal your information.
• One quick fix: diversify your passwords.

If you're still using the same password for everything, it might finally be time to get on that.

While the major cybersecurity vulnerabilities that OpenAI agents helped expose on Wednesday primarily impact the owners and operators of websites, it could also give hackers the opportunity to hijack your personal information, researchers said.

"Be extra careful visiting ANY web site in the next few days," Changpeng Zhao, the cofounder of cryptocurrency platform Binance, said on X.

OpenAI said on Wednesday that researchers using its AI models uncovered two "critical" flaws in the infrastructure of PHP, a popular open-source programming language used on about 70% of the world's websites.

Because digital commerce websites, for instance, can store personal shopper information in PHP systems, that information would be accessible to a bad actor exploiting the web provider's system if that provider hasn't updated it.

The National Security Administration warned that hackers using one of the PHP exploits could "steal sensitive data, disrupt services, or move deeper into a network."

"Even if you yourself are not building software and that's not where your core business is, a lot of your life does depend on companies that depend on those systems," Madeline Lawrence, cofounder of Aikido Security, an application security platform, told Business Insider on Thursday.

"And they could be deeply, deeply vulnerable," she added. She said that one day after the disclosure, cybersecurity platform Cloudflare reported millions of attempts to exploit the vulnerability.

If you do own a website, PHP has released updates it says will help shield websites from hackers. Instructions for applying those updates are available on PHP's homepage.

For everyone else, here are a few tips cybersecurity researchers say you can use to protect your info.

• Don't reuse passwords; use a password manager.
• Check for security advisories from your bank.
• Use two-factor authentication on your devices and accounts — especially for email, banking, and your password manager.
• If your data has been breached, expect more convincing scams and phishing emails.
• Turn auto-updates on and restart your computer weekly.

"You can ask your claude code to audit what on your laptop is out of date and needs updating," Peter Wildeford, head of policy at the AI Policy Network, a bipartisan nonprofit that advocates for safety guardrails and federal oversight, added in a post on X.

Though Lawrence called the vulnerability "very severe," she cautioned against people running to close their bank accounts to protect themselves.

"Assume that if you're getting a notification that your data has been leaked," she said. "Take action on that because you could have credentials or information floating around the dark web."

The European Union has taken a significant step towards revising its digital regulatory framework after member states agreed proposals to amend the General Data Protection Regulation (GDPR), simplify cookie consent requirements and overhaul cybersecurity reporting obligations.

The Council of the European Union adopted its negotiating position on Wednesday, 21st October, clearing the way for negotiations with the European Parliament once MEPs establish their position.

The measures form part of the European Commission’s Digital Omnibus package, introduced in November 2025, and represent one of Brussels’ most substantial attempts to simplify the regulatory obligations imposed on businesses operating across the single market.

Changes to GDPR and personal data rules

The proposed reforms would modify several provisions of the GDPR, which has governed the processing of personal data across the EU since May 2018.

Rather than replacing the legislation, the Council wants to clarify existing obligations, particularly those concerning pseudonymised information, requests for access to personal data and the use of information in scientific research.

The agreed position retains the existing definition of personal data while introducing provisions intended to clarify when pseudonymised information can be linked to an identifiable individual.

Companies would also benefit from simplified procedures for handling manifestly unfounded or excessive data requests and from reduced information requirements in certain low-risk circumstances.

Another proposed change would extend the deadline for notifying authorities of personal data breaches, while establishing more consistent reporting templates across the EU.

For multinational companies, which currently navigate different interpretations of data protection obligations by national authorities, these provisions could reduce compliance costs and administrative duplication.

However, the changes have raised concerns among European privacy regulators.

In a joint opinion published in February, the European Data Protection Board and European Data Protection Supervisor warned that parts of the Commission’s original proposal could create legal uncertainty and undermine existing protections.

They were particularly concerned about proposals affecting the definition of personal data and the Commission’s potential role in determining when pseudonymised information falls outside GDPR requirements.

The Council’s decision to retain the existing definition addresses part of that debate, although the final legislative text remains subject to negotiations.

Fewer cookie banners for internet users

One of the most visible changes would affect the consent notices encountered by Europeans when visiting websites.

Under the Council’s proposal, additional categories of cookies and similar tracking technologies could be used without obtaining explicit consent, provided the relevant legal conditions are satisfied.

The proposed exemptions include technologies necessary to deliver a service, maintain device security or conduct audience measurement.

For website operators, publishers and online businesses, the changes could reduce the number of consent requests displayed to visitors and simplify technical compliance.

The current system has generated extensive legal disputes over whether consent is genuinely voluntary and whether tracking technologies collect information beyond what users have authorised.

EU Today has previously examined the enforcement of these obligations, including a Belgian court ruling concerning the legality of the advertising industry’s consent framework.

The latest proposal would not abolish consent requirements for commercial tracking or behavioural advertising. Technologies falling outside the permitted exemptions would remain subject to the applicable privacy rules.

Cybersecurity reporting and artificial intelligence

The package also addresses the growing number of reporting obligations imposed on European businesses under overlapping cybersecurity legislation.

The Commission originally proposed a single European reporting mechanism for certain data and cybersecurity incidents.

Member states have instead agreed to establish national entry points, supported by an EU-level information system and provisions for coordinating cross-border notifications.

The Council’s position would also clarify the legal grounds for certain uses of personal data in artificial intelligence systems and introduce safeguards for processing sensitive information in specified circumstances.

These provisions follow increasingly complicated disputes over the application of European privacy legislation to AI development and automated decision-making.

As EU Today reported in its coverage of a major GDPR enforcement case involving Uber, automated processing already presents substantial compliance risks for companies operating within the bloc.

Competitiveness drives regulatory reform

The Commission estimates that its wider digital simplification initiative could save European businesses up to €5 billion in administrative costs by 2029.

The initiative reflects pressure from European governments and business organisations to reduce the regulatory fragmentation that makes operating across multiple EU jurisdictions more expensive.

The Digital Omnibus is part of a broader legislative programme influenced by the competitiveness reports produced by former Italian prime ministers Enrico Letta and Mario Draghi.

Under the Council’s negotiating mandate, several existing data-related rules would also be consolidated, while provisions governing the protection of trade secrets would be strengthened.

The European Parliament must now determine its negotiating position before formal discussions between the institutions can begin. Until the legislation is agreed and adopted, existing GDPR, cookie consent and cybersecurity requirements remain in force.

Dutch-Belgian supermarket group Ahold Delhaize has confirmed that malicious activity was responsible for the cybersecurity incident that disrupted its operations across Europe and the United States, forcing the company to take websites, applications and other computer systems offline.

In an official statement issued on Monday, 19 October, the company announced that it had filed a formal complaint with Dutch police and was cooperating with national cybersecurity authorities. Although physical supermarkets have remained open, the disruption has affected online shopping, deliveries and some distribution operations.

The company said investigators had so far found no evidence that sensitive information belonging to customers, employees or business partners had been taken. However, its investigation remains open, and the identity and objectives of those responsible have not been publicly established.

Online services interrupted across several countries

The disruption began on 12 October, when Ahold Delhaize detected suspicious activity within its information technology infrastructure.

The group responded by taking a number of systems offline as a precaution, affecting most of its retail brands in Europe and the United States. The consequences varied considerably between businesses, with some experiencing prolonged interruption to digital services while others were able to restore operations more quickly.

Albert Heijn, the Netherlands’ largest supermarket chain, has been particularly affected. Its website and mobile application have returned online, but home grocery deliveries are not expected to resume until Friday, 23 October.

Orders scheduled before that date have been cancelled, while the company continues preparations for a gradual restoration of its online delivery service.

The incident also interrupted some supply and distribution arrangements, resulting in shortages on supermarket shelves in parts of the Netherlands and Belgium.

In Belgium, Delhaize has restored its online shopping operations. Certain promotional and personalised services were still experiencing difficulties, although the parent company confirmed that its Belgian e-commerce business was operational again.

Dutch retailers Etos and Gall & Gall have also restored their websites. Meanwhile, several American supermarket brands owned by Ahold Delhaize have continued to experience service interruptions.

The group said it expected additional online services in the United States to become available over the coming days.

Dutch authorities investigate

Ahold Delhaize said it notified the Netherlands’ National Cyber Security Centre within 24 hours of detecting the malicious activity.

The company has subsequently provided updates to the authorities and, on Monday, confirmed that a formal police report had been submitted.

Chief executive Frans Muller defended the decision to shut down digital systems, arguing that the investigation had demonstrated the necessity of taking preventive action.

The company has not identified the perpetrators, confirmed whether ransomware was involved or disclosed the technical method used to gain access to its infrastructure.

These distinctions are important because malicious activity does not necessarily establish that information was stolen or that attackers obtained control over every system subsequently taken offline.

The retailer has instead described a controlled restoration process intended to ensure that affected systems can be brought back into operation without exposing the business to further risks.

Ahold Delhaize operates thousands of supermarkets and related retail businesses, including Albert Heijn, Delhaize, Food Lion, Giant Food, Hannaford and Stop & Shop.

Its geographical reach means that a disruption originating within shared corporate infrastructure can affect several national markets, even where individual retail chains maintain separate commercial operations.

Cybersecurity becomes a supply-chain concern

The attack comes amid increasing scrutiny of the vulnerability of European food retailers to digital disruption.

Earlier this month, investigators in France began examining cyberattacks against refrigeration control systems used by hundreds of supermarkets.

Those incidents reportedly affected equipment at chains including Carrefour, Intermarché and Monoprix, with some retailers forced to discard products after refrigeration systems malfunctioned.

There is no established connection between the French incidents and the attack affecting Ahold Delhaize.

Nevertheless, both episodes illustrate the dependence of modern retail operations on interconnected digital systems supporting stock management, refrigeration, logistics, payments and customer services.

The consequences of a serious cyber incident can extend beyond the loss of access to websites. Interruptions to inventory systems, warehouse operations or communications with suppliers can affect the availability of physical products.

This creates particular difficulties for food retailers, where delays in transport and storage can result in the loss of perishable goods.

European regulatory implications

The incident also draws attention to the European Union’s NIS2 cybersecurity framework, which establishes stricter risk-management and incident-reporting obligations for organisations operating in designated sectors.

Food production, processing and distribution are among the activities covered by the directive, although its application to particular companies and operations depends on the relevant legal definitions and national implementing arrangements.

The legislation requires organisations within its scope to establish appropriate cybersecurity protections, address supply-chain risks and notify competent authorities of significant incidents.

Separately, the General Data Protection Regulation establishes notification requirements where personal-data breaches meet the relevant reporting threshold.

Ahold Delhaize’s statement that it has found no evidence of sensitive data being taken does not conclude the technical investigation, but it means that a confirmed theft of personal information should not presently be presented as a fact.

For the company, the immediate challenge remains restoring online services while maintaining normal supermarket operations. The wider commercial consequences, including the cost of the interruption and its effect on sales, have not yet been quantified publicly.

A cyberattack affecting approximately 700 supermarkets in France has exposed serious weaknesses in the digital systems used to control commercial refrigeration, raising concerns about the vulnerability of European food distribution networks and other essential infrastructure.

The attack began overnight on 11–12th October, when intruders gained access to remotely managed refrigeration equipment and altered operating settings, causing refrigerators and freezers to overheat.

Stores belonging to several major supermarket chains were affected, including Intermarché, Netto, Coopérative U, Carrefour and Monoprix. Some were forced to discard substantial quantities of fresh and frozen food.

French Finance Minister Roland Lescure confirmed that approximately 700 of the country’s 10,000 supermarkets had been affected, although the severity of the disruption varied between locations.

The Paris prosecutor’s office has opened an investigation into the attack, including the damage caused by destroyed merchandise and reported fires.

The incident has drawn attention to industrial control systems that are routinely connected to the internet but may receive less cybersecurity protection than corporate networks and customer databases.

Refrigeration systems remotely manipulated

Investigators have established that refrigeration equipment was targeted through vulnerabilities associated with remote monitoring and control systems.

The French cybersecurity authorities identified compromises involving products supplied by Danish manufacturer Danfoss and American company Copeland.

Some of the affected systems used older equipment that no longer received regular security updates.

According to information released by the companies and cybersecurity specialists, certain industrial controllers had been accessible through public internet connections, creating opportunities for unauthorised access.

Hackers reportedly manipulated defrost cycles and increased temperature settings, preventing equipment from maintaining the cold conditions required to preserve food.

The attack affected approximately 300 Intermarché and Netto stores, while Coopérative U reported disruption at around 80 outlets.

Several retailers managed to contain the damage, but others lost substantial quantities of stock.

The consequences extended beyond malfunctioning equipment. Businesses faced the cost of replacing spoiled food, repairing refrigeration systems and restoring normal operations.

The precise financial damage is still being assessed, although estimates from the retail sector indicate that losses across France could amount to tens of millions of euros.

Vulnerabilities in connected equipment

The incident illustrates the security problems created by the growing use of internet-connected industrial equipment.

Modern refrigeration installations allow contractors and maintenance specialists to monitor temperatures, adjust settings and diagnose faults remotely.

These arrangements can reduce operating costs and improve efficiency, but they also create additional access points that attackers may exploit.

Cybersecurity specialists have identified vulnerabilities in commercial refrigeration platforms manufactured by Danfoss and Copeland.

The manufacturers subsequently addressed identified flaws, although older or unsupported equipment remained a concern.

A critical problem for businesses is that industrial machinery often remains operational for many years after its original software has become obsolete.

Replacing entire refrigeration installations can involve substantial expense and operational disruption, encouraging operators to retain equipment that may no longer meet contemporary cybersecurity standards.

The risks are particularly difficult to manage when responsibility for maintenance, software updates and network security is divided between retailers, equipment suppliers and external contractors.

France’s delayed cybersecurity legislation

The attack has renewed scrutiny of France’s implementation of the European Union’s NIS2 Directive, which is intended to strengthen cybersecurity across sectors providing important economic and public services.

The directive establishes common requirements covering risk management, incident reporting, organisational responsibility and protection against cyber threats.

Its scope extends beyond traditional critical infrastructure such as energy, telecommunications and transport to include certain businesses involved in food production, processing and distribution.

EU member states were required to incorporate the directive into national legislation by 17 October 2024.

France was among the countries that received a formal warning from the European Commission in May 2025 over incomplete implementation.

French cybersecurity specialists have since warned that delays have complicated efforts to establish consistent obligations for organisations operating industrial and commercial systems.

However, NIS2 does not automatically cover every supermarket. Its application depends on the nature and size of an organisation and the provisions of national implementing legislation.

The incident therefore raises questions not only about the pace of legislative implementation but also about the practical protection of equipment already in use.

Wider implications for European infrastructure

The disruption demonstrates how a cyberattack can cause physical damage without directly targeting a conventional industrial facility.

Unlike breaches intended to steal customer information, the French incident interfered with machinery responsible for preserving essential products.

The distinction is important for European policymakers, who increasingly face threats to infrastructure that combines digital controls with physical operations.

The European Union’s cybersecurity agency ENISA has organised cross-border exercises to test how authorities and companies would respond to disruption affecting essential services.

The attack itself has been established, but responsibility for it has not been publicly attributed.

French authorities have said there is no immediate threat to national food supplies. Nevertheless, the destruction of merchandise and interruption of ordinary retail operations have demonstrated the potential economic consequences of weaknesses in relatively commonplace equipment.

The continuing investigation must establish how access was obtained, which systems were compromised and whether the vulnerabilities were known to operators before the attack.

For Brussels and national regulators, the case provides a practical test of whether European cybersecurity legislation can translate into effective protection for the connected equipment on which ordinary commercial activities increasingly depend.
