Salutations fellow readers. I hope some of you saw me speak on JoeCrypter last week at CactusCon. As for the slides from my talk, you can view them here.
For those who don’t know, I wrote the reverse engineering challenges this year for the CTF. Most of them were solved, but not all. Perhaps some of you would like a crack at it? Give it a go: https://gironsec.com/cactuscon_re_challenges/index.php
I will be posting the answers in a couple of weeks. For now though, please enjoy the challenges.
Happy cracking!
