This is gonna be huge.
If I calculate correctly, you will be able to detect almost any Windows and Entra ID related attack with less than 20 detections.
You can probably expand them to Linux/MacOS/Azure/AWS/GCP as long as you have the right telemetry as I'll teach higher-order behavioral detection logic that are universal. And they are quite hard to bypass 😎

#ClaudeForBlueTeam - Day 11!
I just cut my SIEM lab noise down by over 80 percent.
Claude can drill into your SIEMs nosiest events, trace what's generating them and tell you exactly what to tune and how many events/second you can save.

Detecting lateral movement with extremely high precision and recall shouldn't be this easy. 😮

@Cyb3rMonk I think there is also HTB module on Sliver that's pretty good

It's a bit late for me as I learned a lot about Sliver C2 framework, but finally someone released a quite cheap course that leverages Sliver.

Access masks are easy to ignore until you hit Access Denied and waste time guessing.
I wrote up a short walkthrough on what access masks are, where they live, and how to inspect them in Process Explorer, the security UI, and a debugger.

Within DeviceEvents (XDR/MDE however you want to call it) you can find this thing, that's like the most confusing event I have ever seen.
I wonder if anyone is utilizing this in any way?????

I have been doing some AMSI bypasses lately, imagine how surprised I was finding out this:
Windows 11 Pro, no MDE, Defender AV -> bypass was successful.
Windows 11 Pro, MDE, Defender AV -> the same bypass was instantly detected.
Huh

@Salsa12__ I have been playing with this technique lately, some EDRs trigger for it quite often

@AlteredSecurity I loved CRTP, so CRTE would be a next level and nice improvement;)
