Solving flAWS

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.

Pentest Cyprus 3.0

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.
