description: The following analytic detects the execution of the SOAPHound binary
|
|
(`soaphound.exe`) with specific command-line arguments. It leverages data from Endpoint
|
|
Detection and Response (EDR) agents, focusing on process names, command-line arguments,
|
|
and other process-related metadata. This activity is significant because SOAPHound
|
|
is a known tool used for credential dumping and other malicious activities. If confirmed
|
|
malicious, this behavior could allow an attacker to extract sensitive information,
|
|
escalate privileges, or persist within the environment, posing a severe threat to
|
|
organizational security.

|
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.
