Story summary

As of October 21, 2026, critical vulnerabilities were discovered in PHP, a widely used web programming language, prompting European and British authorities to recommend that many websites temporarily go dark. This led to several major sites, including government pages in Europe, the BBC, and other organizations like Wikipedia and Pinboard, being taken offline on Wednesday morning as website operators scrambled to apply security updates or risk potential cyberattacks. The vulnerabilities, rated at a critical severity of 9.2 out of 10, could allow hackers to remotely execute code, potentially compromising sensitive data and networks. Reports suggest that up to 70% of the world's websites may be affected by these issues, as PHP underpins large parts of the internet infrastructure. The discovery underscores concerns about the rapid spread of AI in cybersecurity, with some experts calling it "one of the first areas where we are going to see the harmful impact of AI."

🔮 America's lead federal agency for investigating financial crimes added that it would "identify the cyber criminals responsible and bring them to justice", while Binance also said it was working with the FBI. The company also told its users "your money is safe, and we're covering every loss".
🔮 "It was also a bit nerve-racking as anyone who has applied software updates before would know, there's always a chance than an update can cause other issues," he said.
🔮 The woman, in her early thirties, was expecting her third child at the time and said she feared she might lose the baby due to the stress of the attack.
🔮 The former cyber investigator is in a group chat with current agents who are worried their personal information could soon be freely available online to criminals and hostile nation-state hackers.
🔮 Experts say the hack - which the FBI is investigating - could leave agents vulnerable to scams, blackmail and targeted attacks, as well as help criminals impersonate law enforcement officers. "
🔮 I am not sure that we will get such a clear warning shot before it's too late."

🔮 Within hours the hackers had drained his cryptocurrency accounts of £18,000 of savings and disappeared. "It's a horrible feeling to be out a substantial amount - something I wouldn't wish on my worst enemy," the victim, who wanted to stay anonymous, said.

🔮 It succeeded, but went further than he imagined by hacking the gym's online systems, in what is being seen as the latest example of the way AI agents will go to any lengths to carry out the jobs they've been given.
🔮 He told CNN his company - which is a small start-up - will not be taking legal action against OpenAI, but added that these types of hacks are illegal and should remain so. "
🔮 The firm described how the AI worked at superhuman speed but also made strange decisions and mistakes that no human hacker would have made. Hugging Face, which is like an app store for AI tools, said the hacking agents worked relentlessly with thousands of different methods trialled simultaneously. The company first revealed that it had been hacked, external by someone using powerful autonomous AI on 16 July and reported it to police.

he → say → systems
In Mauritius, IT administrator Loganaden Velvindron said he too was flat out since his team realised just how much software relies on PHP. asserted
software → say → PHP
"Many versions of php running are completely end-of-life, so we are having to rebuilding web apps and change code in some cases," he said. asserted
he → run → cases

One major firm in this space issued warnings saying hackers had a working PoC - only to have to retract it. asserted
