Critical vulnerabilities in PHP, a programming language used by roughly 70% of websites worldwide, have triggered a global cybersecurity scramble, with government, school and hospital sites across Europe and beyond taken offline on Wednesday as operators rushed to patch the flaws, which were identified with the assistance of artificial intelligence (Korea Times, Business Korea). The Korean government has issued a nationwide security alert to businesses and website operators over the vulnerabilities, raising its cyber crisis warning level to 'caution' (Korea Times, 한국경제). Korean media report that attackers could execute malicious code on web servers without logging in, raising concerns over personal data leaks and service disruptions, and that security experts say web firewalls alone cannot fully block attacks (조선일보, 동아일보).
