What it detects

This rule detects writes to the Session Manager PlatformExecute registry value, an unusual boot-time execution key the fake FinalShell SwimSnake campaign abuses to trigger a released driver (BEB.exe) for security-software tampering. Adversaries plant execution entries under Session Manager to run code very early and outside common autostart monitoring, making early detection critical for catching driver-based defense evasion before shellcode injection into explorer.exe.
