What it detects

This rule detects WindowsSandbox.exe launched with a .wsb configuration file, the technique MirrorFace uses in Operation AkaiRyu to run AsyncRAT inside Windows Sandbox and evade host-based monitoring. Interactive Windows Sandbox use driven by a dropped .wsb config is uncommon on managed endpoints. This indicates sandbox-based evasion hosting a remote access trojan.
