I'd also love to add calls to native Win32 APIs to this graph, the on-disk binaries themselves and the permissions against them, COM object instantiation/calling, etc.

At that point I see this graph being capable of assisting with the discovery of currently unknown "lolbin" primitives.

This obviously does not guarantee that a function called from one of these binaries will land at a function in kernel32.dll. I'd love to map cross-binary function call graphs. Not sure whether there is an easy solution to that.

A little OpenGraph POC for mapping PE header imports of all .dll and .exe files in a fresh Windows install. These are all the binaries that have some kind of import chain leading to kernel32.dll

This is the kind of research that should invite serious conversation about the trustworthiness of cloud authentication services.

It won't. But it should.

Adalanche searches works way better now - it uses BFS rather than DFS which gave unnecessary long paths at times. This is available in the latest commit on GitHub.

There might be bugs with the new search - let me know if you see any strangeness. Happy hunting :-)

We've got a fresh #BloodHoundBasics post from @jonas-bk.bsky.social!

Ever wondered about those obscure AD special identity groups that quietly grant permissions to every principal in your environment?

With BloodHound, you can uncover compromising permissions tied to these groups.

From November 2016:

This is how I used to design BloodHound's entity panels. Just a text editor to list out what I as a red-teamer wanted to see, with the corresponding (then new) cypher queries listed as well.

Simple, VERY low-fidelity mockup, but really helped during the design phase.
