EDR-Testing-Script
This repository contains simple script to test EDR solutions against Mitre ATT&CK/LOLBAS/Invoke-CradleCrafter frameworks. This project is very much in its infancy right now. It is written as a single batch script so it can be easily uploaded and run (as opposed to un-zipped, compiled and installed). The script can run either as a normal user or as Administrator however not giving it high privilages will fail some tests.
Right now this script only works on Windows and should work with most security endpoint solutions.
How To
Run the runtests script and observe alerts coming to your EDR console. Cross-verify these alerts to check if your EDR solution identified them correctly. Most tests will just execute calc.exe but it can be easily modified to try to download and exec i.e. Mimikatz. DO NOT USE THIS SCRIPTS ON PRODUCTION SYSTEMS, INSTEAD DEPLOY THIS IN A VM WITH EDR.
Why
Because it is hard to figure out how accurate EDR's are. Most EDR solutions are sold as silver bullet for security but it is actually difficult to check how many different malicious attacks are correctly identified and contained. MITRE & LOLBAS do pretty good job at mapping common tools and techniques which are being used by attackers out there to pivot, execute code and progress through internal networks and this tool will executes these attacks to helps organizations verify the accuracy of deployed EDR product.
Weaponization
The script executes calc.exe. You can replace this easily with metasploit executable where needed but payloads will need to be modified to reflect this. As payloads are hosted on GitHub, if you really want to test your EDR I would suggest to move them to hosted server somewhere else as GitHub is generally not considered malicious. In theory, serving malicious payload (i.e. metasploit) hosted on external server would be much better way of detecting if EDR triggers or not against specific technique.
Tested On
- Windows 7 x86
- Windows 7 x64
- Windows 10 x64

Run with Metasploit
If you want to run this script as part of Purple Team exercise then simple MSF module execution will do:
msf > use post/multi/manage/upload_exec
msf post(upload_exec) > set lfile /tmp/runtests.bat
lfile => /tmp/runtests.bat
msf post(upload_exec) > set rfile C:\\Users\\Public\\runtests.bat
rfile => C:\\Users\\Public\\runtests.bat
msf post(upload_exec) > set session 1
session => 1
msf post(upload_exec) > run
Run with Cobalt Strike
Using plugin in Cobalt folder, simply load it and click "EDR TEST > RUN ALL TESTS" against specified target.

Everyone working on awesome projects like LOLBAS or Invoke-CradleCrafter
