PHP2Shell Exploit Used in AI-Assisted Attacks to Hijack Exposed Servers

Attackers are chaining PHP2Shell vulnerabilities with kernel exploits to gain complete root control over internet-facing servers. Researchers observed AI-assisted threat actors using this technique to successfully compromise dozens of servers and breach sensitive networks. Canadian businesses with exposed, unpatched web infrastructure risk total server takeover and severe operational disruption.
