Potential RjvPlatform.DLL Sideloading From Non-Default Location

Sigma Rules

View Source
Summary
The detection rule is designed to identify suspicious behavior related to the dynamic linking library (DLL) sideloading of 'RjvPlatform.dll' by the executable 'SystemResetPlatform.exe'. This is particularly significant due to the nature of DLL sideloading, a technique utilized in privilege escalation attacks where a legitimate application is tricked into loading a malicious DLL from a non-standard or non-default directory. The rule specifies that the image 'SystemResetPlatform.exe' should be located in a non-default path while loading 'RjvPlatform.dll' which typically resides within the 'C:\Windows\System32\SystemResetPlatform\' directory. The rule captures instances when 'SystemResetPlatform.exe' attempts to load 'RjvPlatform.dll' ending with a specified string and filters out legitimate scenarios where the image is in its default, expected path. Given the potential for exploitation, this detection carries a high alert level but is expected to have few false positives, as unlikely legitimate scenarios are indicated.
