Summary
This rule aims to detect potential DLL sideloading exploits involving the common Windows library comctl32.dll. DLL sideloading is a technique whereby a legitimate process is tricked into loading a malicious DLL instead of the intended library. In this case, the detection specifically looks for instances where certain applications (like logonUI.exe, werFault.exe, consent.exe, narrator.exe, and wermgr.exe) have a modified or unexpected path ending with 'comctl32.dll'. The rule uses the property of image loading events in the Windows system, recognizing when an application that is supposed to load system libraries instead interacts with this potentially compromised DLL, allowing for unauthorized actions or privilege escalation. Given the high severity of this type of vulnerability, it's crucial to monitor such attempts closely as they can lead to further exploitation of the operating system's privileges.
