AI-powered hacking era begins after critical PHP bug found

theguardian.com — October 23, 2026 at 08:01 PM UTC

Cybersecurity leaders are warning of a new era of AI-enabled hacking after a critical vulnerability was found in the PHP programming language, which powers millions of websites and may have been unpatched for years. Executives predict AI will expose more fundamental weaknesses in global internet infrastructure in coming months. The discovery, part of what is called "Black October," used AI to identify the flaw, announced on 21 October, which some experts estimated put 70% of all internet sites at risk. Tech executives, including Sam Altman and Anthropic's Jason Clinton, warn of a "vulnerability tsunami" that will overwhelm patching efforts, with Cloudflare CEO Matthew Prince saying the next two years will be "incredibly fraught." Attempts to exploit the PHP bug have already begun, with government and private sites in the US and UK temporarily taken down to patch it, and the NSA issuing an urgent alert. Cloudflare reported exploit attempts jumped from thousands to millions within hours of the announcement, while researchers at Wiz called it "among the most severe vulnerabilities discovered in PHP, and arguably in software history."
