Over the past couple years, I have come to know the .NET platform pretty well, from both a developer’s and a reverse engineer’s standpoint. I can’t always quite say the same about people in the security community. In fact, more often than not, I encounter a lot of “experts” in the scene (e.g., on Twitter, YouTube, forums, blogs, webinars, talks, chat logs…) that come up with factoids about .N...

At last, as promised in my previous post, with a huge delay I finally managed to finalize my Flare-On12 write-ups. Overall, it was a really good and fun set of challenges, and as always, the latter ones humbling me, reminding me how much I still have to learn in the field of RE. My only main complaint: I wish there were more realistic/malware related challenges. This year felt very CTF-y :^). ...

Today a bit of a different, more rambly post. DEFCON and Grand Canyon It’s been a couple of months since I’ve been back from BSidesLV 2025 and DEFCON 33. Long story short, it was awesome and extra special this year for me. I met so many cool and talented people that have humbled me in many ways. From the talks to the people (shoutout Malware Village), there is so much cool stuff around that I...

Ever seen a binary that looks like a .NET binary based on its strings, but .NET decompilers are not able to open them? .NET or not? You may just be dealing with a Native AOT binary! That may sound scary, native decompilation is much harder than .NET decompilation. However, what if you could make Ghidra look like this: Ghidra Native AOT Extension In this post, we will discuss Native AOT...

Today a short post. Over the past half year or so, I have been dealing with some pretty serious medical complications that made me unable to do a lot of programming, reversing and blogging. On doctor’s advice, I stayed low and only sat behind a computer as much as my body would allow me to. Sorry for the inactivity! Nonetheless, I haven’t been fully idle. Flare-On 11 has come to a close last ...
