There is quite interesting “always open” CTF challenge, wherein one should use AWS specific security mistakes (flaws) to solve it. Funny enough, its name is flAWS. There are 6 total levels with increasing difficulty. Each level contains several hints for those who stuck. Below are my steps of trying to solve the flAWS challenge.
In October 8, there was a PentestCyprus 3.0, a CTF competition in Larnaca, where I participated and won it.
There were total 25 tasks in 6 categories: Web, Cryptography, Forensics, Reverse Engineering, PWN and Miscellaneous. First, I will tell about tasks I’ve managed to do in 3 hours of contest. If I will have free time, I will try to solve the rest and publish solutions to them.
