Description
An attacker might abuse the Windows DLL search order by planting in the same folder a signed binary that will load the attacker's malicious module.
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
Possible DLL Side-Loading of a module with highly suspicious characteristics
