PHP2Shell exploit attempts try to deploy Potassium Mirai
Original title: PHP2Shell Exploit Attempts Hit Millions as Attackers Try to Deploy Mirai Malware
Sophos says the attempts failed, while SOCRadar found exploit tooling aimed at PHP 8.4.26.
Threat actors are attempting to exploit PHP2Shell flaws CVE-2026-109618 and CVE-2026-109619 for unauthenticated remote code execution and to deploy Potassium, a Mirai-derived botnet. Sophos says the observed attempts were unsuccessful and that reliable exploitation appears harder than expected. SOCRadar found exploit tooling for PHP 8.4.26 and screening scripts, but reported no shell access on screened sites as of October 22, 2026.
Unconfirmed: Sophos says no successful PHP2Shell attack was observed and actors appear to be struggling; SOCRadar reported no shell access on screened sites.
- Fixed PHP versions are 8.5.12, 8.4.27, 8.3.36, and 8.2.35.
- Potassium uses C2 134.199.154.64 and can launch flood attacks.
- Observed floods targeted 45.88.138.0 and 45.88.138.44 in a Ukrainian network.
- Arctic Wolf says both samples include inactive Ethereum Name Service C2 configuration.

Threat actors have been observed unsuccessfully attempting to exploit the newly disclosed PHP2Shell vulnerabilities to rope infected systems into a Mirai botnet variant called Potassium, as it emerges that weaponizing the flaws may be harder than previously thought. The attacks aim to exploit CVE-2026-109618 and CVE-2026-109619 (CVSS scores: 9. 2), which can result in unauthenticated remote
