ARMpwn and ARMpwn Challenge

“ARMPwn: Repository to train/learn memory corruption exploitation on the ARM platform. This is the material of a workshop I prepared for my CTF Team”

ARMPWN challenge write-up:
A few weeks ago, I came accross @5aelo repo called armpwn for people wanting to have a bit of ARM fun. I had recently spent some time adding new features and perfectionning old ones to my exploit helper gdb-gef and I saw there a perfect practice case. On top of that, I had nothing better to do yesterday ☺ This challenge was really fun, and made so much easier thanks to gef especially to defeat real life protections (NX/ASLR/PIC/Canary), and on a different architecture (Intel is so ‘90). This is mostly why I’m doing this write-up, but feel curious and do it by yourself. Fun time ahead guaranteed ☺ […]
