Did you know that Crystal Palace can merge multiple COFFs straight into a single PIC blob? It means we can produce complete PIC programs from modular parts, without needing a dedicated loader. Plus access to DFR and shared libraries... just lovely.

I found it far more enjoyable doing string replacements in Aggressor than in the C2 profile because the feedback loop is so much quicker - no need to stop/start the server after every change.

Took me long enough, but finally managed to hook into mscoreei.dll and stack spoof load library calls for clr.dll.

Crystal Kit is just too powerful.

I'm legit blown away. We can use DFR with Nt* APIs now!

My motivation behind this is to hook & spoof APIs that aren't supported by BeaconGate, such as CreateProcessA. Passing the PICO memory allocation data to Beacon via BUD also ensures that a custom Sleepmask can free it after ExitThread is called.

Working on a fun Crystal Palace loader that hooks APIs and pushes them through a call stack spoofing PICO.

I learned some Java @raphaelmudge.bsky.social !! 😅

Playing with @raphaelmudge.bsky.social's latest CP update (it's very cool). I have mixed feelings about merging COFFs though. It simplifies overall development and gives the loader fewer jobs to do, but on the other hand you lose some flexibility about where each "part" goes in memory.

lol amazing. If only I knew of a cool server to join.

I think I've got a nice way to produce debug builds for Crystal Palace loaders. It produces an EXE that works with WinDbg so you can debug against the source code, with locals, etc.

Thanks to this excellent video, we now have a new emoji in the ZPS Discord server, the :sadmudge:. Seriously, this is a good video for getting started with PIC dev and cleared up quite a few things for me.

Hooking arbitrary BOFs via @raphaelmudge.bsky.social's Crystal Palace is very cool. I'm going to explore more to see if I can rip out the SleepMask and BeaconGate into their own PICOs, rather than using the official BOF codebases.

Having another look at Raffi's Crystal Palace PIC loaders today. This time as a post-ex reflective loader with embedded function pointers for GetModuleHandle & GetProcAddress.

Used some janky glue to tie into the BEACON_RDLL_GENERATE hook.

Only a few tweaks needed to get this working with Beacon. Very cool.
