AI-found PHP flaw puts 70% of web at risk

A critical security vulnerability has been found in PHP, the programming language used by about 70% of websites worldwide, with the discovery credited to artificial intelligence. The flaw lets hackers take over servers without admin passwords, prompting US, Japanese and European government agencies, banks, schools and hospitals to temporarily shut down sites as a precaution. The US NSA advised all PHP users to update immediately or go offline, and South Korea issued a 'caution' cyber alert. However, a French security firm reported that 8 out of 10 domestic PHP servers run old versions that cannot be patched, raising particular concern in Korea. Ami Luttwak, co-founder of Wiz, called it "the most serious security vulnerability AI has found."
