MicrosoftSystem64 Scheduled Task Persistence
Detects the creation of a scheduled task named '\MicrosoftSystem64', which is a specific Indicator of Compromise (IoC) associated with the Windows variant of the FAMOUS CHOLLIMA / MicrosoftSystem64 RAT malware for persistence. The rule identifies this activity through Windows Event Log (Event ID 4698 for task creation), command-line execution of 'schtasks.exe' with '/create' and the specific task name, and Defender EDR telemetry for scheduled task creation.
