Critical security vulnerabilities in PHP, a programming language used by about 70% of websites worldwide, were discovered with the help of artificial intelligence, prompting government agencies and companies around the world to shut down websites. Korea Times reports that the Korean government issued a nationwide security alert to businesses and website operators over the flaws. European governments temporarily suspended some official websites as a precaution, and the U.S. NSA advised going offline if patches cannot be applied, according to Maeil Business Newspaper. Yonhap notes the discovery would have been impossible without AI, and experts warn hackers could now use AI for large-scale attacks, calling it a 'double-edged sword.'
