Windows Masquerading Explorer As Child Process

splApache-2.0from splunk/security_content

The following analytic identifies instances where explorer.exe is spawned by unusual parent processes such as cmd.exe, powershell.exe, or regsvr32.exe. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process and parent process relationships. This activity is significant because explorer.exe is typically initiated by userinit.exe, and deviations from this norm can indicate code injection or process masquerading attempts by malware like Qakbot. If confirmed malicious, this behavior could allow attackers to execute arbitrary code, evade detection, and maintain persistence within the environment.
