Cloudflare sees millions of exploit attempts after PHP disclosure

Cloud services company Cloudflare reported an influx of exploitation attempts following the public disclosure of critical vulnerabilities in the widely used programming language PHP. CEO Matthew Prince stated on X that thousands of exploitation attempts were observed in the 10 hours prior to the announcement, which surged to hundreds of thousands within 2 hours and millions shortly after the disclosure.

Government websites in Europe and other regions went offline as a result of the vulnerabilities, causing website operators to scramble to protect their systems. Japanese lender Mitsubishi UFJ Financial Group temporarily suspended some internet services due to emergency measures. PHP developers released urgent fixes to address the vulnerabilities, urging all users to apply the updates immediately.

Japanese Prime Minister Sanae Takaichi encouraged website owners to check for PHP usage and prepare to apply the fixes, while Japan's Finance Ministry temporarily suspended some website content and services while implementing security measures.
