    Detector tags: Scheduled tasks Analytics
    Attacker's goals: Attackers may attempt to use the command to gain persistence on the endpoint using recurring tasks.
    Investigative actions: Check whether the executing process is benign and if this was a desired behavior as part of its normal execution flow.
  • Signed process creates a scheduled task via file access Informational 1 variation

    A signed process created a scheduled task via file access. Attackers may create scheduled tasks for execution and to establish persistence.

    Activation:
    14 Days
    Training:
    30 Days
    Test:
    N/A (single event)
    Deduplication:

    ATT&CK techniques: Scheduled Task/Job (T1053)
    Required data: XDR Agent
    Detector tags: Scheduled tasks Analytics
    Attacker's goals: An attacker may gain persistence and execute malicious tools via scheduled tasks.
    Investigative actions: Check the created task file and look for the action triggered by the task.

    Variations
