They are tightening measures due to a global PHP vulnerability endangering the internet in Japan

Government and corporate websites worldwide have shut down due to a critical security risk affecting PHP, which powers about 70% of the web. Attackers could exploit vulnerabilities to execute arbitrary code remotely without passwords. This has led to precautionary measures by banks, airlines, and government organizations, particularly in Asia, where many servers run outdated PHP versions. Japan's SoftBank suspended its emergency alert system for mobile users during maintenance. In response, Japan's industry minister announced proactive measures, including an AI-supported hacker simulation team to identify vulnerabilities before real attackers can exploit them.
