What it detects

This rule detects remote monitoring and management tools such as SimpleHelp or MeshAgent executing from within a GoAnywhere installation directory. Microsoft observed attackers deploying these RMM tools under GoAnywhere folders following CVE-2025-10035 exploitation to maintain access. RMM binaries running from a file-transfer application path are out of place and indicate attacker-installed remote access.
