What it detects

This rule detects creation of scheduled tasks named msiInstall2 or ekShell2, matching the persistence mechanism of the Potemkin loader and RMMProject intrusion. Operators register these named tasks to relaunch loader and shell components across reboots. These specific task names are strong indicators of this campaign's persistence.
