ATT&CK analytic guidance

DET0333 Cross-Platform Detection of Scheduled Task/Job Abuse via `at` Utility

AN0943 Analytic 0943

Detects creation of scheduled tasks via `at.exe` or WMI `Win32_ScheduledJob` class, followed by execution of anomalous processes by svchost.exe or taskeng.exe.

AN0944 Analytic 0944

Detects usage of `at` command to schedule jobs, followed by job execution and modification of job files under /var/spool/cron/atjobs.

AN0945 Analytic 0945

Detects user or root invocation of `at` command to schedule a job, followed by job execution using LaunchServices and activity in /usr/lib/cron/at.

Threat actor context

These are explicit actor-to-technique associations in the existing Threat Matrix snapshot, not attribution of an event or proof that a detector identifies the actor. No tool-to-actor relationship is inferred.
