The LabyREnth competition ran from 15th July to 14th Aug. I only managed to find time to do the first Windows challenge. It was a tricky one and I was only able to work at it in fits and starts, often with days or weeks between sessions. However, I learnt quite a few handy new things while working on it, so I’m writing this as a reference for myself and as an example of the dead-ends and rabbit holes of the analysis process for those who are interested.

Challenge:

Welcome to Vertinet.

This problem follows the same specifications as the previous Verticode problem, except that you have to solve many of them by developing a client to communicate with the server available at problems1.2016q1.sctf.io:50000. Good luck.

This was a nice little challenge from sCTF 2016. I’m trying to work on more tricky stuff, but this one looked like fun and I couldn’t resist.

Challenge:

Welcome to Verticode, the new method of translating text into vertical codes.

I only managed one task in the 2016 VolgaCTF, but it was a fun one. Coding a tic tac toe bot.

Challenge:

Tic-Tac-Toe

An important step towards the strong AI is the ability of an artificial agent to solve a well-defined problem. 
A project by the name 'tic-tac-toe' was one of such test problems. It's still up...
