🔧 I develop #AsmResolver, ✍️ blog at and sometimes 👾 hack with @Shellphish

Did you know you could write entire #csharp programs just by using the "await" keyword?

OK, well not really, but I spent some weekends developing AwaitFuscator: A (dumb) #obfuscator that turns your #dotnet program into nothing but "await" expressions!

With less than 1h left on the clock, #flareon13 finally in the bag!

Taylor series were not on my bingo card 😅

I can finally rest...

I’m seeing a lot of Slibes (slop-vibe-slides) lately. AI can throw together a pretty-looking slide deck faster than you can blink. However, just like slop-text, slop-slides show a lack of respect for your audience. If it’s worth my time to read, it’s worth your time to edit.

If you are doing #FlareOn this year and want to rank yourself against other 𝗵𝘂𝗺𝗮𝗻𝘀 we made an unofficial leaderboard. Honour system only, but it's something.

[Washi @washi_dev]

@raysan5 Sadly, library devs don't get as much funding/attention as the people writing frontends around said libraries.

Even though libraries make the frontends possible, it is easier for an investor to see potential in a user-ready product vs something only devs interact with.

[Washi @washi_dev]

@BwitneyHouston Maybe we can set one up ourselves as a separate leaderboard? 😆

[Washi @washi_dev]

So who is down to set up a human-only leaderboard for this year🙃

#flareon13

[expy @expend20]

I gave Opus one prompt and all nine Flare-On 12 challenges. It solved them all in 4h 28m. No IDA, no decompiler, no debugger, and it never ran a single binary. Python with capstone, unicorn and z3.

@expend20 You can't really, but if there's any honesty left in this community, we can hope for good sportsmanship 🫠

[Washi @washi_dev]

@hasherezade This is exactly my stance too. I am not looking to improve my AI herding skills during flare-on.

[Washi @washi_dev]

@hasherezade I wouldn't hold your breath 😂

[Washi @washi_dev]

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

The timer for #flareon13 started on https://t.co/fEUtjEEqD4

I will likely participate, but not sure I will try to speed-solve it like previous years.

Last year was already somewhat pay-to-win. I expect this year to be worse. I don't see any fun in competing against unlimited AI

@danglenoir CILFI is built on top of AsmResolver😉

You can also use it programmatically instead of through the command-line, and thus directly embed your signatures in your program

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.

This is actually a very well-explained beginner series on #dotnet #reversing. We need more good beginner-friendly sources like these.

🧩 Video 2 in the .NET obfuscation series is now public!

https://t.co/tZ5tSQDta9

In this video we'll explore the Global Module Constructor (.cctor) to analyze the impact of anti-debugging and anti-tamper protections.

[Washi @washi_dev]

@CaptWake Haha! Custom attributes have been a thing well before AI 🤣

The choice of FQNs was an inexplicable but conscious human decision.

[Washi @washi_dev]

Custom attributes in #dotnet give me nightmares.

Read my new blog post to learn why:

@vinopaljiri Oh I'm not trying to downplay your research, just trying to explain one reason there may not have been the reaction you would've liked. The post didn't give us much to work with, so it's hard to have opinions about it as well.

I'll wait for the full details in your release 😉
