Patents was quite a difficult box from gb.yolo (who’s now a teammate of mine!) with a realistic pwn in the end. Overall, it was a very enjoyable box that took a while! Before I start, I would like to thank D3v17 and pottm, my teammates who worked with me on this box. Additionally, I would like to thank oep, Sp3eD, R4J, and Deimos who I collaborated with at times throughout and after the box.

Recently the Qualys Research Team did an amazing job discovering a Heap overflow vulnerability in Sudo. In the next sections, we will analyze the bug and we will write an exploit to gain root privileges on Debain 10.
Rope2 by R4J has been my favorite box on HackTheBox by far. It wasn’t really related to pentesting, but was an immersive exploit dev experience
