Websites go dark after FBI and UK cyber chiefs urged owners to patch an AI-found PHP flaw or shut down
Computer hackers, as Cloudflare CEO Matthew Prince warned attackers were already probing the PHP vulnerability in the ten hours before its public disclosure, with around 70% of websites thought to be affected.
Amazon Web Services says the flaw, dubbed 'PHP2Shell', is now 'being broadly exploited in the wild'. Cloudflare boss Matthew Prince said exploit attempts jumped to tens of thousands within 45 minutes of the announcement. The Office for Budget Responsibility, Oxford City Council and City of Edinburgh Council pulled their sites. Minister Douglas Alexander insists next week's Budget is secure.
PHP underpins almost 70% of websites, including WordPress and Magento, according to Cloudflare.
The fix was meant to stay secret until sites had patched, but it leaked.
Wiz researchers call it arguably among the most severe flaws 'in software history'.
