Potential Libvlc.DLL Sideloading

Sigma Rules

View Source
Summary
This detection rule aims to identify potential DLL sideloading events involving the libvlc.dll file, which is an essential dynamic link library for VLC media player software. DLL sideloading is a technique often exploited by attackers to execute malicious code by placing a rogue DLL in the same directory as a legitimate executable, allowing the executable to load the malicious DLL instead of the intended one. The rule specifically targets instances where libvlc.dll is loaded from unexpected locations, contrasting with its usual legitimate paths, which are typically found in C:\Program Files (x86)\VideoLAN\VLC\ or C:\Program Files\VideoLAN\VLC\. By monitoring for occurrences of libvlc.dll loading outside of these directories, this rule facilitates the detection of potentially malicious sideloading attempts, enhancing security posture against privilege escalation and persistence strategies employed by attackers.
