name: Ping Sleep Batch Command id: ce058d6c-79f2-11ec-b476-acde48001122 version: 1 date: '2022-01-20' author: Teoderick Contreras, Splunk type: Anomaly datamodel: - Endpoint 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="*>*") 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. references: - https://www.microsoft.com/security/blog/2022/01/15/destructive-malware-targeting-ukrainian-organizations/ tags: analytic_story: - WhisperGate automated_detection_testing: passed cis20: - CIS 3 - CIS 5 - CIS 16 confidence: 60 context: - Source:Endpoint - Stage:Defense Evasion dataset: - https://media.githubusercontent.com/media/splunk/attack_data/master/datasets/attack_techniques/T1497.003/ping_sleep/sysmon.log impact: 60 kill_chain_phases: - Exploitation message: suspicious $process$ commandline run in $dest$ mitre_attack_id: - T1497 - T1497.003 nist: - DE.CM observable: - name: user type: User role: - Victim - name: dest type: Hostname role: - Victim product: - Splunk Enterprise - Splunk Enterprise Security - Splunk Cloud required_fields: - _time - Processes.dest - Processes.user - Processes.parent_process_name - Processes.parent_process - Processes.original_file_name - Processes.process_name - Processes.process - Processes.process_id - Processes.parent_process_path - Processes.process_path - Processes.parent_process_id risk_score: 36 security_domain: endpoint supported_tas: - Splunk_TA_microsoft_sysmon asset_type: Endpoint
