Organizations should prioritize patching to 8.5.12, 8.4.27, 8.3.36 or 8.2.35 and monitor for memory-leak probes. Expect commercial and underground exploits to proliferate within weeks as the VulnCheck technique is reverse-engineered.

⚡ Prediction

Hunt.io: PHP2Shell-related scanning from Mirai infrastructure will exceed 500 unique source IPs daily by October 28 without corresponding successful RCE reports.
