AI-Discovered PHP Flaws Shut Websites Worldwide

Critical vulnerabilities in PHP, used by about 70% of websites, were found with AI assistance, prompting governments and companies globally to take websites offline as a precaution. The U.S. NSA issued an alert on Oct. 21, and PHP developers released an emergency patch the same day, with European institutions like the University of Geneva suspending access. In South Korea, the government issued a nationwide security alert to businesses and operators, Yonhap reports, and experts warn hackers could now use AI for large-scale attacks, calling it a 'double-edged sword.'
