Description
A signed DLL was loaded into a Microsoft-signed process. This DLL hash and signature vendor are rare, which might indicate an attacker performing DLL hijacking.
Attacker's Goals
An attacker is attempting to load an untrusted module into a trusted context to avoid detection, gain persistence or to perform privilege escalation.
Investigative actions
- Investigate the loaded module to verify if it is malicious.
- Investigate if the loading process and the loaded module reside in legitimate locations.
Variations
A rare DLL, signed by an uncommon vendor, was hijacked into an injected Microsoft process
