What it detects

This rule detects wscript executing a Fat named JavaScript file that then launches PowerShell as used in the RevengeHotels campaign to stage VenomRAT. The threat actor delivers phishing JS droppers whose PowerShell child fetches the remote access trojan. A script host running a Fat JS file with a PowerShell descendant is a strong sign of this loader chain.
