description: 'The following analytic identifies the execution of ping sleep batch commands.
|
|
|
|
It leverages data from Endpoint Detection and Response (EDR) agents, focusing on
|
|
|
|
process and parent process command-line details. This activity is significant as
|
|
|
|
it indicates an attempt to delay malicious code execution, potentially evading detection
|
|
|
|
or sandbox analysis. If confirmed malicious, this technique allows attackers to
|
|
|
|
bypass security measures, making it harder to detect and analyze their activities,
|
|
|
|
thereby increasing the risk of prolonged unauthorized access and potential data
|
|
|
|
exfiltration.

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.
