AWS says PHP2Shell vulnerability was exploited four days before patch release
AWS research shows that at least one attacker began attempting to exploit two critical PHP vulnerabilities, PHP2Shell, as early as October 17, four days before the public fix on Wednesday. AWS Chief Information Security Officer CJ Moses said the attempt came from an IP associated with a commercial anonymization network, and it is not yet clear how the attacker obtained vulnerability information in advance. He noted that AI-assisted analysis has lowered the cost of turning a patch diff or advisory into a usable exploit, enabling more attackers to act within hours or even minutes after vulnerability details are made public.
