This detection rule identifies potential DLL sideloading of an unsigned version of 'dbghelp.dll' when loaded by Sysinternals' VMMap tool. The rule monitors Windows image load events, specifically looking for instances where 'dbghelp.dll' is loaded from the 'C:\Debuggers\' directory while VMMap executables (either 'vmmap.exe' or 'vmmap64.exe') are in use. A key condition for triggering this detection is that the 'dbghelp.dll' file is not signed, indicative of possible malicious activity designed to sideload a malicious DLL. This method is often employed to elevate privileges or bypass security mechanisms, which aligns with known attack techniques for defense evasion and persistence. The rule has a high severity level due to the significant risks associated with unsigned or tampered DLLs being used in security-sensitive contexts.
