description: The following analytic identifies the creation or deletion of a scheduled task using schtasks.exe with flags - create or delete being passed on the command-line. This has been associated with

the Dragonfly threat actor, and the SUNBURST attack against Solarwinds.

how_to_implement: You must be ingesting endpoint data that tracks process activity,
|
||||
including parent-child relationships from your endpoints to populate the Endpoint
|
||||
data model in the Processes node. The command-line arguments are mapped to the "process"
|
||||
field in the Endpoint data model.
|
||||
known_false_positives: Tasks should not be manually created via CLI, this is rarely
|
||||
done by admins as well
|
||||
references: []
|
||||
how_to_implement: To successfully implement this search you need to be ingesting information on process that include the name of the process responsible for the changes from your endpoints into the `Endpoint` datamodel in the `Processes` node. In addition, confirm the latest CIM App 4.20 or higher is installed and the latest TA for the endpoint product.
|
||||
known_false_positives: It is possible scripts or administrators may trigger this analytic. Filter as needed based on parent process, application.
