description: The following detection identifies the latest behavior utilized by different
|
||||
malware families (including TA551, IcedID). This detection identifies any Windows Office Product spawning `bitsadmin.exe`. In malicious instances, the command-line of `bitsadmin.exe`
|
||||
will contain a URL to a remote destination or similar command-line arguments as `/transfer /Download /priority Foreground`. In addition, Threat
|
||||
Research has released a detections identifying suspicious use of `bitsadmin.exe`. In this instance, we narrow our detection down
|
||||
to the Office suite as a parent process. During triage, review all file modifications.
|
||||
Capture and analyze any artifacts on disk. The Office Product, or `bitsadmin.exe` will
|
||||
have reached out to a remote destination, capture and block the IPs or domain. Review
|
||||
additional parallel processes for further activity.

on process that include the name of the process responsible for the changes from

your endpoints into the `Endpoint` datamodel in the `Processes` node.
