What it detects

This rule detects wscript.exe executing a VBScript file from the AppData Roaming directory using the //B silent flag. WSHRAT and its Vjw0rm component drop and run .vbs payloads from Roaming to avoid user visibility. Silent script execution from this user-writable path is a common malware staging technique.
