Ask what Korea is talking about.

Critical vulnerabilities in PHP, a programming language used by roughly 70% of websites worldwide, have forced government, school, and hospital websites across Europe and beyond offline as organizations rush to patch the flaws, the Korea Times reports. The flaws, identified with AI assistance, allow attackers to execute malicious code on web servers without login, raising fears of data leaks and service outages. In Korea, the government has issued a nationwide security alert and raised its cyber crisis warning to 'attention' (주의), Yonhap reports, estimating about 110,000 vulnerable servers domestically. However, Chosun Ilbo reports that 82% of Korean PHP servers run outdated versions that cannot be patched, citing French security firm CybelAngel. Korean media and security experts urge immediate updates, noting that web application firewalls alone cannot fully block attacks.
