Never would I have expected this for a spare time hobby project. 1 million downloads is crazy, thank you all ❤️ #asmresolver #malware #dotnet #reversing

I hate writing pattern-matching code for function identification in my .NET #deobfuscator and config extractor. So I built a tool to help me out with it. Meet CILFI: A function identification tool for .NET binaries: 👉https://blog.washi.dev/posts/cilfi/ #dotnet #reversing #malware #ioc

Over the past couple years, I have come to know the #dotnet platform pretty well, from a developer's and a #reversing standpoint. I can’t always say the same the #infosec community. Today, I decided to rant a little (or maybe a lot 🙃) 👉 blog.washi.dev/posts/miscon...

Better late than never, I finally managed to finalize my #flareon12 write-ups😄 Overall, it was a fun set of challenges and the latter ones a reminder of how much I still have to learn in the field of RE :). 👉 blog.washi.dev/posts/flareo... 👉 washi1337.github.io/ctf-writeups...

After #flareon11 challenge 7, I got inspired to build tooling for #dotnet Native AOT reverse engineering. As such, I built a #Ghidra Analyzer that can automatically recover most .NET types, methods and frozen objects (e.g., strings). 👉https://blog.washi.dev/posts/recovering-nativeaot-metadata/
