I spent the last month reverse engineering Call of Duty's anti-cheat! Blog post here: ssno.cc/posts/reversin…

Last Thursday, I gave a webinar on anti-reverse engineering techniques like obfuscation, anti-debug, anti-tamper etc, including practical examples. Recording, slides and examples are now available. youtube.com/watch?v=Ie1eZS… github.com/emproof-com/we…

Disassembly algorithms are often a trade-off. My new blog post analyzes linear sweep and recursive traversal, exploring their strengths and weaknesses in a self-built disassemblers. nicolo.dev/en/blog/disass…

We are only two weeks out from some of the most engaging and immersive trainings available for security professionals, all happening at RE//verse! Today is the final day to register if you want your name professionally printed on your badge—late registrations will have names

My class on code deobfuscation at @recontml (June 24-27) is now open for registration! Learn how to analyze obfuscated code and break it by writing custom tools using symbolic execution, SMT solving, and program synthesis. Details & Register: recon.cx/2025/trainingS…

Last call to get a ticket for my deobfuscation next week in Orlando!

Come learn software Deobfuscation with Tim Blazytko at Recon 2025 June 23-26 #ReverseEngineering #Cybersecurity #malware #softwarecopyprotection For more details: recon.cx/2025/training.…

New heuristic in my #BinaryNinja plugin obfuscation_detection: Duplicate Subgraphs uses iterative context hashing to spot repeated multi-block code. We merge each block’s signature with its successors over multiple rounds for efficiency. Link: github.com/mrphrazer/obfu…

Would you look at that, it's tmp.0ut Volume 4! Happy Friday, hope you enjoy this latest issue! tmpout.sh/4/

Just built an MCP for Ghidra. Now basically any LLM (Claude, Gemini, local...) can Reverse Engineer malware for you. With the right prompting, it automates a *ton* of tedious tasks. One-shot markups of entire binaries with just a click. Open source, on Github now.

Hacked together an IDA Pro MCP server in a few hours tonight! I gave Claude a simple crackme, but forgot to remove the source code from my project folder and in the end it cheated to find the solution🤦‍♂️ Variable renaming and retyping is implemented though, so that might be

Happy to announce that nicolodev and I will be giving a talk titled "Breaking Mixed Boolean-Arithmetic Obfuscation in Real-World Applications" at REcon More information will follow in the coming days.

Was really cool to hang out and demonstrate the IDA Pro MCP with a bit more nuance than 2 minute videos! 🔥

More details: nicolodev and I discuss the current state of MBA (de)obfuscation and their applications REcon We’ll also introduce a new #BinaryNinja plugin for simplifying MBAs in the decompiler. Details: cfp.recon.cx/recon-2025/fea…

Excited to teach my class on software deobfuscation in Paris at Hexacon, Oct 6–9, 2025! Learn advanced techniques to defeat state-of-the-art obfuscation in DRMs & APT malware. hexacon.fr/trainer/blazyt…

I’ll be in Berlin for offensivecon the entire week. If you see me around feel free to say hi or lemme know if you wanna meet

#OffensiveCon25 videos are now up! youtube.com/playlist?list=…

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…
