Machine Interrogation To Identify Gaps & Techniques for Execution
MITIG&TE is a Windows binary that automatically enumerates Windows settings in order to identify MITRE ATT&CK™ techniques mitigated due to configuration hardening and existing endpoint controls. It relies heavily on the amazing work of the MITRE ATT&CK™ team and the mitigations defined for each of the techniques. It is written in C# and it's dependent on .NET Framework v4.5.
The tool aims to allow security teams to easily account and track the impact endpoint configuration hardening and controls have against their threat profile. Additionally it can be used to identify configuration hardening settings that can further improve security posture. Use MITIG&TE to:
- Identify techniques that are currently mitigated/less likely to be executed successfully, posing less risk to your environment
- Surface non-applied endpoint controls that can improve endpoint hardening
- Combine with threat intelligence and your existing detection capabilities to get a holistic view of your security posture mapped against ATT&CK
MITIG&TE is currently under development. Current coverage here.
If you would like to try MITIG&TE you can either compile it yourself or use the precompiled executable provided as part of the CI. For maximum effectiveness, consider running MITIG&TE as an administrator and specifying a user for the least privilege checks. Ideally, that user should have the same privileges as a typical end-user in your environment. By default, MITIG&TE performs the checks for the last logged-in user. When executed, MITIG&TE will pull the latest ATT&CK information and iterate over all the Windows techniques, pulling information on the mitigations defined for each one.
Mitigate.exe -OutFile=results.json # Outputs findings into results.json
Mitigate.exe -OutFile=results.json -UserName=user1 # Outputs findings into results.json and performs least privilege checks for user1
Mitigate.exe -OutFile=results.csv -UserName=user1 # Outputs findings into results.csv and performs least privilege checks for user1
In addition to the console output, MITIG&TE outputs a json file that can be ingested by the ATT&CK™ Navigator for easy visualisation. Colour scheme used:
No mitigations were detected
Some mitigation were detected
All mitigations were detected
Technique cannot be mitigated
Hovering over a specific technique in the navigator will provide more context on the checks performed. For an interactive example, take a look here.
A CSV output can also be generated if a CSV is specified as the output file. This is suitable for users looking to get the results in a structured format apart from JSON.
Mitig&te is fully modular and enumerations can be added by dropping the relevant file into the logical file location, include in the Visual Studio Solution Explorer and compile. An enumeration template is provided at ./Mitigate/EnumerationTemplate.cs.
If you are considering contributing and have further questions don't hesitate to open an issue.
MITIG&TE has been tested on Windows 10 64bit in a simple AD lab based on Detection Lab. However, for any bug reports and features request please raise an issue. For now, bugs will carry higher priority than new feature requests.
MITIG&TE makes use of a number of slightly adapted code snippets found through research for its checks. I have marked those code snippets and added a link to the source in each case but please don't hesitate to contact me if you find anything not listed.
MITIG&TE is to be used only when authorized and/or for educational purposes only and comes with no guarantee. Its findings should not be actioned before testing and consideration on user impact.
