What it detects

This rule detects PowerShell invoked to run an executable located under the Roaming AppData directory, matching the BatLoader chain that launches a dropped payload such as zkoko.exe. It is associated with the BatLoader malware campaign reported by Uptycs. Legitimate installers rarely execute binaries out of the user Roaming profile through PowerShell, so this behavior indicates staged malware execution.
