What it detects

This rule detects the AutoIt3 interpreter running a script from a user writable location such as AppData, Temp or ProgramData, matching DarkGate loader behavior that executes multiple AutoIt scripts staged after a JavaScript or LNK dropper. Some legitimate installers bundle AutoIt so parentage and path should be reviewed.
