Websites Shut Down Globally After AI Finds Cybersecurity Flaw Affecting 70% of the Internet
Researchers used AI to expose PHP2Shell flaws that could let attackers read passwords, and the PHP Foundation issued patches immediately.
- The National Security Agency and the European Union cybersecurity agency advised companies Thursday to immediately patch two critical vulnerabilities in PHP, a programming language powering 70% of the world's websites.
- Researchers from OpenAI and Wiz used AI to uncover 'PHP2Shell' flaws that had remained hidden in the codebase for more than a decade before being disclosed Wednesday.
- Government services in the UK, France, Denmark, Finland, and the Netherlands, alongside companies like ANA and MUFG, took systems offline Thursday as a 'precautionary measure' to implement security updates.
- UK government minister Elizabeth Lloyd told the House of Lords Thursday that nearly three dozen government services were unavailable while experts worked with OpenAI and international partners to fix exposures.
- Cybersecurity expert James Sullivan noted the episode marks an 'AI inflection point' where frontier models can rapidly exploit vulnerabilities that previously required months of human work.
