Description

An attacker may be trying to avoid detection by injecting their malicious code into a legitimate Windows system binary.

• Attackers may inject code into processes to evade process-based defenses, as well as possibly elevate privileges.

Investigative actions

• Check whether the injecting process is benign and if this was a desired behavior as part of its normal execution flow.
