VMProtect, anti-cheats, DRM — how much of today's obfuscation survives agentic reverse engineering?
Find out in our talk with @nicolodev:

I fully agree: even targets such as anti-cheats and gaming DRMs have become significantly easier to analyze with agents, if you know how to guide them and validate their results.
@nicolodev and I will about that at @reconmtl:

Previous generations of software protection (DRM perspective) have always relied on code complexity (for RE), compute limitations, and human limitations as the guarantees that kept hacking timelines reasonably long. That's changed now. Beyond the acceleration in vulnerability research and malware analysis, the same new reality applies to software protection, and security by obscurity, or assuming the attacker is limited in compute and motivation, no longer works.

Join us at REcon 2026 for a deep dive into deobfuscation! @mr_phrazer and I will share some insights on the evolving landscape. Stay tuned!

@lyq_sqsp yes agree this is why I have mentioned that CFG restructuring for that decompilation pipeline is already established. Out of curiosity, CUDA also supports jump tables.
English
IMHO we probably don't need a very powerful structurizer, since most real world CUDA kernels are designed for speed and have far fewer branches than typical programs after compilation. Semantic-level recovery of the types/memory operations may be more important, given how sparse Nvidia's documentation is about the SASS.
English
Amazing talk! btw I have also vibe coded something that may help with some of the gaps. The structurizer algorithms and the dataflow analysis are still premature though.

@TheEmrakul @REverseConf Thank you! Ouch, I’m sorry for that but feel free to write me an e-mail :)
English
@nicolodev @REverseConf Great talk Nicolò! Missed the opportunity to talk to you but there will be other chances maybe
English
@Farenain @alexjplaskett Thanks, I'm going to write more in the following months. Stay tuned!

I’ll be speaking at RE//verse 2026 about reverse engineering CUDA-based kernels.
Don’t miss the opportunity to learn more about CUDA and challenges for decompilation!
RE//verse@REverseConf
Nicolò Altamura (@nicolodev) digs into decompiling CUDA kernels at RE//verse 2026! He takes a look at how GPU execution and NVIDIA’s IRs change the usual assumptions for decompilers and shows early work on a Binary Ninja PTX plugin aimed at real CUDA reversing.

I’m glad to share that our paper "Assessing the Effectiveness of the Tigress Obfuscator Against MOPSA and BinaryNinja" has been published in the proceedings of the CheckMATE Workshop.
Check out how we used MOPSA and Binary Ninja to evaluate obfuscation!

It was a great honor to share the stage with @mr_phrazer to present MBA deobfuscation using our powerful BinaryNinja plugin.
An incredible experience at REcon 2025 — thank you to everyone who made it unforgettable! Check out the recording!

The new version of my #BinaryNinja plugin Obfuscation Analysis (v1.2) adds recursive function inlining in the decompiler. It collapses call-heavy code into a single function; analysis, constant propagation, DCE and other analyses work across boundaries.

We just presented our new Binary Ninja plugin for deobfuscation of Mixed Boolean Arithmetic expressions at REcon25. Check it out!

Simplify the reverse engineering of obfuscated binaries using MBA expressions with our new plugin!
Easy to use, and shows the results directly to Binary Ninja!

New #BinaryNinja plugin: Obfuscation Analysis Simplifies arithmetic obfuscation (MBA) directly in the decompiler (see demo below). Also identifies functions with corrupted disassembly. Co-authored by @nicolodev; available in the plugin manager. github.com/mrphrazer/obfu…
