description: This analytic will identify the possible execution of ping sleep batch
|
|
commands. This technique was seen in several malware samples and is used to trigger
|
|
sleep times without explicitly calling sleep functions or commandlets. The goal
|
|
is to delay the execution of malicious code and bypass detection or sandbox analysis.
|
|
This detection can be a good indicator of a process delaying its execution for
|
|
malicious purposes.

search: '| tstats `security_content_summariesonly` count min(_time) as firstTime max(_time)
|
|
as lastTime from datamodel=Endpoint.Processes where `process_ping` (Processes.parent_process
|
|
= "*ping*" Processes.parent_process = *-n* Processes.parent_process="* Nul*"Processes.parent_process="*>*")
|
|

|
|
|`security_content_ctime(lastTime)` | `ping_sleep_batch_command_filter`'
|
|
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: Administrator or network operator may execute this command.
|
|
Please update the filter macros to remove false positives.
