Suspicious Command Patterns In Scheduled Task Creation
Detects scheduled task creation using the 'schtasks' utility that incorporates suspicious or uncommon command-line patterns. This includes tasks scheduled to run frequently (e.g., every minute) or as the 'system' user, combined with common command interpreters ('cmd'), or containing keywords often associated with malicious activity like PowerShell download commands, obfuscation techniques, or execution from temporary/public user directories. It also flags the use of scripting engines (cscript, wscript) or curl within scheduled tasks.
