Description
An attacker may inject payloads into processes via Microsoft Office. While legitimate in certain cases, code injection can also be used in malicious ways.
Attacker's Goals
- An attacker attempts to gain code execution via a phishing document.
- Attackers may inject code into processes to evade process-based defenses, as well as possibly elevate privileges.
Investigative actions
- Check the source of the document (received by mail or loaded locally).
- Check whether the injecting process is benign, and if this was a desired behavior as part of its normal execution flow.
