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).

During #flareon11, I learned how to use a plugin to automate x64dbg with Python. In this video, I'll show how to set it up, get started, and then walk through my final tracing script.

#FlareOn11 prize arrived! Very neat!

Just received this shiny token of reverse engineering glory from the Flare-On Challenge 2024! Grateful for the sleepless nights. #FlareOn11

Flare-On 2024 - Washi's CTF WriteUps

I just published my writeups for all challenges of #flareon11:

Hope you like them as much as I liked writing them!

Redirecting…

Had a lot of fun with #flareon11 this year! Managed to finish all 10 challenges, and get writeups done for all but two (maybe someday?). Check them out here:

#flareon11 challenge 2 down!!!! I was just being dumb about it. Did not need to spend nearly as much time debugging as I did. Feels good to get the flag though!

Stuck on #flareon11 challenge 2 💀

I get it to do the thing and dump the file, but I'm not having any success with finding the right input. I think I understand how the right input would make things work. It's just finding it that's got me scratching my head.

Always wild to me how varying in perceived difficulty the #flareon challenges are.

1 - straightforward
2 - way more difficult; huge time waster
3 - took me forever to understand
4 - relatively straightforward again

Now onto 5 🥳 #flareon11

This is for my friend J-NAS if he was here i would be happy Bluesky this is what I do just in case if he is here then I will be very glad and will be there to meet him. #Flareon #pokemon #pokegirl #PokemonGo #flareon11 #commission #furrycommission #artmoots #artmoot #originalcharates #fanart #anime

Finally finished #flareon11 🥲 Lost a lot of time AND SANITY on question 9. Learned a lot and had fun as always.

Thanks a lot to @nickharbour and team for this year's #FlareOn11. Solid challenges overall. I especially enjoyed 5, 7 & 9. Looking forward to seeing solutions for 9. I feel like there are multiple things I could have done better but overall I learned a lot this year.

Challenge 9 of #FlareOn11 is nasty and I'm all here for it. :)

Had an unusually fast start in #FlareOn11 with five challenges already down so I guess karma will bite me hard in the later ones but first it's time to go touch some grass.
