What it detects

This rule detects wscript.exe running a file named trash.dll through the VBScript engine with LitterDrifter specific arguments. This behavior belongs to the Gamaredon LitterDrifter USB worm which uses the Windows script host to launch its orchestrator module. Detecting it exposes initial execution of the worm on the host.
