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 to take websites offline as a precaution. Korea Times reports the Korean government issued a nationwide security alert to businesses and website operators. Yonhap notes the flaws could not have been found without AI, and Chosun Ilbo reports European governments temporarily suspended some official sites. The PHP development team released an emergency patch on Oct. 21, according to Chosun Ilbo. Korean media frame AI as a double-edged sword: it found the flaws, but hackers could also use AI for large-scale attacks. Donga Ilbo's editorial says the incident shows the information security system must be rebuilt for the AI era, and Kyunghyang Shinmun quotes experts saying "theoretically possible only" attacks are now real, predicting future AI-versus-AI battles.
