AI Finds Critical PHP Flaws, Websites Down Worldwide

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 globally to shut down websites as they scramble to patch the flaws. The Korea Times reports the Korean government has issued a nationwide security alert to businesses and website operators, while Yonhap notes the flaws could not have been found without AI. European governments have temporarily suspended some official websites as a precaution, and the U.S. NSA has advised going offline if patches are not applied, according to Maeil Business Newspaper. Korean media highlight that the vulnerabilities, which may have existed for years, were identified by AI, raising fears that hackers could use AI for large-scale attacks. Experts quoted in Kyunghyang Shinmun call AI a 'double-edged sword,' with one saying, 'It was only theoretically possible... now it's a battle between AIs.'
