TOMORROW: Join us for a demo of OST and find out how we to address the need for stealthy and operationally secure red teaming tools that cover the full attack chain.

Still very much an early WIP, but the Crystal Palace-based Mythic agent I'm working on can be found here:

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.

A scalpel, a hammer, and a foot gun Last month, I released a Yara signature generator for Crystal Palace. AKA, an invariant content observation tool. I then used the feature to document the physics of various content-signature parame…

This is now committed along with a few other changes like using the newer CPL Java API.

Working on a small improvement to Crystal Kit - masking heap memory.

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.

Next week at WWHF Mile High I'll present a major update to roadrecon, with some awesome features I wanted to add for a while! Friday 9am in track 1 for those attending 😀

More than I ever thought I'd write about Yara signatures. Oh also, Crystal Palace has a Yara rule generator too.

In addition to some new commands, this post goes into a lot of details regarding Crystal Palace's binary transformations. If you're interested in how it does some things under-the-hood, give this a read.

Keeping bin2bin out of the bin Happy New Year. I’ve got another Crystal Palace and Tradecraft Garden update for you. My focus this development cycle was making Crystal Palace’s binary transformation framework more robust. …

Another TCG update. +shatter, +regdance, and -O1 MinGW support.

Bigger emphasis in this cycle was hardening the binary transformation foundation--which led to some adventures (details in the post)

Pokemon Yellow Ash% :: 2:27 IGT :: TAS YouTube video by avatar00000

Works!

I managed it: marketplace.visualstudio.com/items?itemNa...

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?

I've written a VSCode extension that provides syntax highlighting for Crystal Palace spec files. I'll throw it up on the marketplace if I can figure out how 😅
