Summary
This detection rule addresses potential DLL sideloading of the 'DbgModel.dll' file, a technique often exploited by attackers to execute malicious code by tricking the system into loading a rogue or modified version of a legitimate DLL. The rule focuses on monitoring the loading of 'DbgModel.dll' specifically, when it does not occur from the trusted system directories such as 'C:\Windows\System32', 'C:\Windows\SysWOW64', and 'C:\Windows\WinSxS', as well as other specified optional locations like Windows Debugger application directories. This is a key behavior that may indicate an attempt at evasion or exploitation, as the legitimate usage of 'DbgModel.dll' typically occurs from these standard paths. By detecting when this DLL is loaded from atypical directories, the rule helps identify potentially malicious activities and enhances the security posture against DLL sideloading attacks, which are commonly used to bypass detection mechanisms. False positives may arise from legitimate applications that maintain their own versions of 'DbgModel.dll'. The detection is categorized under medium severity due to the potential impact of such an evasion technique, reinforcing the need for vigilance in monitoring DLL interactions.
