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 :).

Long overdue, but here’s my writeup for #FlareOn12 Task 9: hshrzd.wordpress.com/2025/11/20/f...

#flareon12 was fun. Thanks to @mandiant.com
for organizing.

Finally managed to sit down this weekend and finish #flareon12. The last one was a bit of a struggle and I made a lot of mistakes but got there in the end. Thanks a lot Nick Harbour and team for another successful edition. Looking forward to write-ups.

Finally done with #FlareOn12. What a ride! I am looking forward to read other people’s solutions, especially of those who did the 9th task quickly.

4/9! I keep overcomplicating these. Spent way too long on four just to realize the answer was in front of me the whole time...

The write-ups I do for these are going to be funny 😂

I think I get what to do for challenge 3, I just can't figure out how to do it. Which also makes me think I could be wrong about the whole thing lol 😆

Oh well, I'll look at it more tomorrow. Maybe sleeping on it will help. I'll keep reading the pdf spec too, it's been helpful.

Apparently I need to read up on PDF file formats...

#flareon12 reduced to four weeks, meanwhile the first week I'm preparing a talk and work traveling ...

I should tack on days and sequester myself in a hotel room with room service the entire time
