Crystal-Kit/crystalkit.yar at main Β· rasta-mouse/Crystal-Kit Evasion kit for Cobalt Strike. Contribute to rasta-mouse/Crystal-Kit development by creating an account on GitHub.

I've added some YARA rules to the Crystal-Kit repo, covering both the loader and the tradecraft PICO. I was pleasantly surprised to see the generator target aspects like heap obfuscation, call stack spoofing, CFG bypass, and memory cleanup.

Breaking content signatures with 'ised' This is "Breaking content signatures with 'ised'" by AFF-WG on Vimeo, the home for high quality videos and the people who love them.

So, when I was writing my latest blog post, a few typos got in there. It's how you know I wrote it. :)

I really wanted to ship that day. The engineering was solid though. I put serious tortured (over-)thinking into the design & impl. decisions. I'm thrilled with the result.

I've been playing with a C2 built around PIC modularity for the last few weeks. C2 comms are merged into the agent at link time and output as shellcode. COFFs are transformed into PICOs for postex. Evasion tradecraft can be woven in via spec files. Very scriptable using Sleep.

Sure, makes sense. You can't just leave the APIs in this scenario though, because Crystal Palace throws the error "Function xxx is not in MODULE$Function format". Maybe we need a new command to skip relocating specified functions? Or maybe some other way to deal with it that fits with your plans.

The idea was to merge hooks into a BOF, 'make coff', then run via beacon_inline_execute. I don't think we want to attach the Beacon BOF APIs to funcs within the merged COFF though. What would you attach them to? Can't we just leave/ignore them so Beacon can link them to the proper internal funcs?
