Websites down: what is PHP and how has it raised AI hacking fears?

AI tools helped Wiz Research and security firm Calif uncover vulnerabilities in PHP, a programming language used by an estimated 70 percent of websites. A fix released Wednesday prompted organisations to take apps and sites, including the Paris police website, offline while they secure their code. Researchers have seen no evidence of attacks exploiting the flaws so far, but sites that delay updating could remain vulnerable.
