description: The following analytic identifies the common command-line argument used
|
|
by SOAPHound `soaphound.exe`. Being the script is publicly available, function names may be modified,
|
|
but these changes are dependent upon the operator. In most instances the defaults
|
|
are used.
|
|
It does not cover the entirety of every argument in order to avoid false positives.

|
how_to_implement: The detection is based on data that originates from Endpoint Detection
|
|
and Response (EDR) agents. These agents are designed to provide security-related
|
|
telemetry from the endpoints where the agent is installed. To implement this search,
|
|
you must ingest logs that contain the process GUID, process name, and parent process.
|
|
Additionally, you must ingest complete command-line executions. These logs must
|
|
be processed using the appropriate Splunk Technology Add-ons that are specific to
|
|
the EDR product. The logs must also be mapped to the `Processes` node of the `Endpoint`
|
|
data model. Use the Splunk Common Information Model (CIM) to normalize the field
|
|
names and speed up the data modeling process.
|
|
known_false_positives: False positives should be limited as the command-line arguments
|
|
are specific to SOAPHound. Filter as needed.
