$I came across a great persistence mechanism and created a Sigma rule for it. Just drop your batch script or add a line that points to your payload inside C:\Windows\Setup\Scripts\ErrorHandler.cmd, and upon execution of C:\Windows\System32\oobe\Setup.exe, the payload will run. In the clip below, I have cmd.exe /c calc.exe as the payload. If ErrorHandler doesn't exist, you can create it along with the directory. Thanks to @Hexacorn for posting about it 🙏 In regards to the rest binaries under the C:\Windows\System32\oobe\ directory, most of them will not work, whereas others will force a restart (i.e. audit.exe) 🔗:$

I created the first draft of a website for the EDR telemetry project to help people quickly compare vendor telemetry visibility. What do you think about it? Are there any specific features you want to see for the website? Built with ChatGPT 4o with canvas (wanted to test it out😂) EDR Telemetry project 🔗:
