Secret Blizzard’s Kazuar malware has evolved from a traditional backdoor into a modular botnet optimized for stealth and persistence. This upgrade aligns with the Russian state actor’s espionage-focused operations. msft.it/6016vRGD6 While many threat actors rely on increasing usage of native tools (living-off-the-land binaries (LOLBins)) to avoid detection, Kazuar’s evolution highlights how Secret Blizzard is engineering resilience and stealth directly into their tooling. Our latest blog breaks down Kazuar’s architecture and botnet operations, and provides protection and detection guidance for defenders:

@Myrtus0x0 “AI is replacing reverse engineering” when they run strings.exe on samples and call themselves reverse engineers

i built an entire x86 CPU emulator in CSS (no javascript) you can write programs in C, compile them to x86 machine code with GCC, and run them inside CSS
@RussianPanda9xx @HuntressLabs You guys over at Huntress are killing it with the quantity and quality of blogs that are coming out!!!

Stop talking about doing things and just do them. The incessant theory crafting about how to learn something, what the best books are, what courses to take, where the best place to learn etc... is tedious dithering. If you actually wanted to do it, you would be doing it. Endless talking isn't a strategy. You don't need another reddit thread, youtube deep dive or curated book list to get started. You are not researching, you are procrastinating. If you actually cared about doing the thing, you’d already be doing it. You romanticize the idea of doing something so much that you forget it actually requires effort. You are stalling because deep down, you know you won’t follow through. Now prove me wrong and actually start learning how to hack, or whatever it is you never shutup about wanting to do.

Deobfuscation result is below 🤠 If anyone is interested in exploring binary deobfuscation or just wanna mess around with Miasm's symbolic execution, feel free to check out my repo.
Had some time to kill before my next gig so I developed this Python tool to fully deobfuscate binaries that are obfuscated with ollvm's control flow flattening. github.com/cdong1012/ollv…
Huge thanks to @MrT4ntr4 for the inspiration and the work from mrt4ntr4.github.io/MODeflattener/!
@ransomsec Oof good catch! I’ll fix this soon. Thank you!
Reviving my blog with a complete analysis of the latest #LockBit #ransomware v4.0 Green! 🤠 chuongdong.com/reverse%20engi… h/t to @fwosar & @demonslay335 for all the crypto helps! Huge thanks to @BushidoToken & @CuratedIntel for the threat intelligence insight too! 🙏
@JershMagersh Coming to MSTIC in a few weeks! I’m super excited!
@JershMagersh @offby1security Just read through the blog! This is awesome work 🫡. Since we all target that runtime_slicebytetostring subroutine, I think the garble author might change or obfuscate this away in the future lol
