Detect Security Software Discovery in Sumo Logic CSE
Adversaries enumerate installed security software, defensive tools, and monitoring agents prior to executing payloads or deploying evasion techniques. By identifying what endpoint protection, EDR, firewalls, and cloud monitoring agents are present, adversaries can determine whether to proceed with infection, disable specific defenses, or select evasion techniques tailored to the detected product. Common methods include WMI queries to the SecurityCenter2 namespace (enumerating AntiVirusProduct, FirewallProduct, AntiSpywareProduct classes), PowerShell Get-WmiObject/Get-CimInstance targeting security product WMI classes, tasklist and WMIC process enumeration filtered to known AV/EDR binary names, and registry inspection of installed software keys for security vendor paths. Threat actors including Darkhotel, Clop, QakBot, Raspberry Robin, TONESHELL (Mustang Panda), and Sidewinder are documented performing this technique in the wild.

Data Sources
Required Tables
False Positives & Tuning
- Endpoint management and patch management systems (e.g., SCCM, Qualys, Rapid7) that regularly check WMI SecurityCenter2 for compliance posture reporting
- SOC or helpdesk runbooks that include checking AV product status via PowerShell or WMIC as part of standard triage procedures for incident response tickets
- Software deployment scripts that verify pre-existing security product presence before installing new endpoint agents to avoid conflicts

Testing Methodology
Validate this detection against 4 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 1WMI SecurityCenter2 AV Enumeration via WMIC
Expected signal: Sysmon Event ID 1: Process Create with Image=wmic.exe, CommandLine containing 'SecurityCenter2' and 'AntiVirusProduct'. Security Event ID 4688 (if command line auditing enabled). Microsoft-Windows-WMI-Activity/Operational Event ID 5857 for SecurityCenter2 provider load.
- Test 2PowerShell Get-WmiObject AntiVirusProduct Enumeration
Expected signal: Sysmon Event ID 1: Process Create with Image=powershell.exe, CommandLine containing 'SecurityCenter2' and 'AntiVirusProduct'. PowerShell ScriptBlock Log Event ID 4104 capturing the full Get-WmiObject command. No network connection expected.
- Test 3Tasklist Process Enumeration for AV Binary Names
Expected signal: Multiple Sysmon Event ID 1 entries for tasklist.exe, each with CommandLine containing the respective AV binary name filter. Security Event ID 4688 entries if command line auditing is enabled. No file or network events expected.
- Test 4Registry Query for Installed Security Software
Expected signal: Multiple Sysmon Event ID 1 entries for reg.exe with CommandLine containing 'query' and the respective vendor path. Security Event ID 4688 if command line auditing enabled. Registry queries will return data on installed products or 'ERROR: The system was unable to find the specified registry key or value' for absent products.
