Mockingjay Slips By EDR Tools With Process Injection Technique

By leveraging misconfigured DLLs instead of EDR-monitored APIs, the new “Mockingjay” technique injects malicious code into running processes while completely evading endpoint detection solutions. This process injection method bypasses traditional security by abusing trusted, but vulnerable, DLLs.

SOC Analysis:
Attackers are shifting to multi-staged attacks that use known-vulnerable DLLs, a tactic known as Bring Your Own Vulnerable Driver (BYOVD). While harder to detect, some EDRs can flag these DLLs. Our SOC team can help identify these risks through targeted threat hunting and behavior analysis.
