What it detects

This rule detects the renamed setup.exe stager executed with the doit argument from the 2FAGuard working directory, the GUI-suppressing invocation Nimbus Manticore uses through its BackupCheck scheduled task to load the native main.dll payload directly. Adversaries leverage this argument to run the implant without the decoy interface, making detection useful for catching the persistence stage of the infection chain.
