Windows Binary Proxy Execution Mavinject DLL Injection

splApache-2.0from splunk/security_content

The following analytic detects the use of mavinject.exe for DLL injection into running processes, identified by specific command-line parameters such as /INJECTRUNNING and /HMODULE. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and command-line executions. This activity is significant because it indicates potential arbitrary code execution, a common tactic for malware deployment and persistence. If confirmed malicious, this could allow attackers to execute unauthorized code, escalate privileges, and maintain persistence within the environment, posing a severe security risk.
