What it detects

This rule detects PowerShell creating a scheduled task named with the PythonLauncher prefix, the logon persistence UAT-11795 registers for its Starland RAT as reported by Cisco Talos. The operators combine New-ScheduledTask with a PythonLauncher task name to relaunch the implant elevated at each logon. Matching this naming and API pattern reveals attacker persistence distinct from routine task creation.
