Ask what Korea is talking about.

Critical vulnerabilities in PHP, a programming language used by about 70% of websites worldwide, were discovered with the help of artificial intelligence, prompting governments and companies globally to take websites offline. The Korea Times reports that the Korean government issued a nationwide security alert to businesses and website operators over the flaws, which allow hackers to penetrate servers without login. Yonhap notes the discovery would have been impossible without AI, and Chosun Ilbo says European countries temporarily suspended government websites as a precaution, with PHP developers releasing an emergency patch on Oct. 21. Maeil Business reports the U.S. NSA advised going offline if patches aren't applied, and that the PHP foundation had known signs two years ago but couldn't fix them. Korean media frame this as a 'double-edged sword': AI found the flaws, but hackers could use AI for large-scale attacks, with experts quoted by Kyunghyang saying 'it was only theoretically possible... now it's a battle between AIs.'
