name: Ping Sleep Batch Command

type: Anomaly
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.
data_source:
- Sysmon Event ID 1
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="*>*")
OR (Processes.process = "*ping*" Processes.process = *-n* Processes.process="* Nul*"Processes.process="*>*")
by Processes.parent_process_name Processes.parent_process Processes.process_name
Processes.original_file_name Processes.process Processes.process_id Processes.process_guid
Processes.user Processes.dest | `drop_dm_object_name("Processes")` | `security_content_ctime(firstTime)`
|`security_content_ctime(lastTime)` | `ping_sleep_batch_command_filter`'
how_to_implement: To successfully implement this search, you need to be ingesting
logs with the process name, parent process, and command-line executions from your
endpoints. If you are using Sysmon, you must have at least version 6.0.4 of the
Sysmon TA.
known_false_positives: Administrator or network operator may execute this command.
Please update the filter macros to remove false positives.
