Detect System Service Discovery in Elastic Security
Adversaries may try to gather information about registered local system services to shape follow-on behaviors. Common techniques include using sc query, tasklist /svc, net start, systemctl --type=service, and WMI queries (win32_service) to enumerate running and installed services. This reconnaissance helps adversaries identify security products to disable, lateral movement opportunities via vulnerable services, and persistence mechanisms already in place. Malware families including Ursnif, Kwampirs, Comnie, Elise, and SLOTHFULMEDIA all leverage service enumeration as part of their post-compromise discovery phase.

Elastic Detection Query
process where event.type == "start" and (

)Detects T1007 System Service Discovery using Elastic EQL against process creation events sourced from Elastic Endpoint or Winlogbeat with Sysmon. Identifies service enumeration via sc.exe query, tasklist /svc, net start, wmic win32_service, and PowerShell Get-Service. Uses ECS process.name and process.command_line wildcard matching for broad coverage across Windows endpoints.
Data Sources
Required Tables
False Positives & Tuning
- IT administrators using sc.exe or net start interactively during routine service troubleshooting or change management windows
- Software deployment and patch management platforms (SCCM, Ansible, Chef, Puppet) that verify service states as part of pre- or post-deployment health checks
- Security and monitoring agents (antivirus, EDR, SIEM forwarders) that enumerate competing software or validate required services during installation or scheduled inventory collection

Testing Methodology
Validate this detection against 5 adversary techniques from Atomic Red Team. Each test below lists the behaviour to exercise and the telemetry you should expect to see. Executable commands and cleanup steps are available with Pro.
- Test 1Service Enumeration via sc query
Expected signal: Sysmon Event ID 1: Process Create with Image=sc.exe, CommandLine containing 'query type= all state= all'. Sysmon Event ID 11: File Create for %TEMP%\services_sc.txt. Security Event ID 4688 (if process creation auditing with command line enabled).
- Test 2Service Enumeration via tasklist /svc
Expected signal: Sysmon Event ID 1: Process Create with Image=tasklist.exe, CommandLine containing '/svc'. Sysmon Event ID 11: File Create for %TEMP%\services_tasklist.txt. The output maps service names to hosting process PIDs and executable paths.
- Test 3Service Enumeration via net start with output redirect
Expected signal: Sysmon Event ID 1: Process Create with Image=net.exe (or net1.exe), CommandLine containing 'start'. Sysmon Event ID 11: File Create for %TEMP%\df00tech-services.dat. Security Event ID 4688 if process auditing enabled.
- Test 4WMI Win32_Service Enumeration via PowerShell
Expected signal: Sysmon Event ID 1: Process Create with Image=powershell.exe, CommandLine containing 'Get-WmiObject' and 'Win32_Service'. PowerShell ScriptBlock Log Event ID 4104 with full command. WMI Activity Log Event ID 5857 (WMI provider load). No separate child process is created — the WMI query runs in-process.
- Test 5Linux Service Enumeration via systemctl
Expected signal: Auditd execve records for systemctl and service binaries (if auditd configured with execve rules: '-a always,exit -F arch=b64 -S execve'). Sysmon for Linux Event ID 1 (if deployed): Process Create with Image=/usr/bin/systemctl and CommandLine containing 'list-units --type=service'. File creation in /tmp for output files.
