Walkthrough of nebula wargame from level 10 to level 19Continue reading
In this blog post we will walk through the solutions of the levels 0 to 9 of the Nebula wargame, which is hosted on http://exploit-exercises.com. This writeup will force me to memorize commands better and exercise a bit. I fear that this writeup is of no use for other people, since you hopefully want to solve those exercises on your own :)

Solution for Natas web security wargame with by XORing the plaintext with the ciphertext...
Currently I am playing some wargames on overthewire.org.
The first 10 levels were very easy and everyone with some technical knowledge and programming experience should be able to solve them. But somehow I got stuck for a few hours on level 11. The task is to modify a XOR encrypted cookie. For some reason I couldn't figure out how to obtain the xor key that was used.
The challenge was to reverse engineer the ...Continue reading

and furthermore there are 3 very different modes ...Continue reading
Depth First Search and Breadth First Search
I am right in front of a ton of exams and I need to learn about
algorithms and data structures. When I read about pseudocode of Graph
traversal algorithms, I thought:
Why not actually implement them in a real programming language? So I did so and now you can study my code now here. I guess this problem was solved a thousand times before, but I learnt something and I hope my approach has some uniqueness to it.
Additionlay, you can also generate ...Continue reading
