Task

There's a fun and quirky IRC bot to play with. It responds to commands in private chat but also in #hacklu-saloon on freenode. We think it's involved in a devious scheme that distracts people to get their money pickpocketed. So be careful!

Solution

We deal with IRC-bot named barmixer-bot in this task. It can understand some commands that starts with "!" symbol.

In these tasks we were given a service which:

• accepts .cpp file
• compiles it via MSVS10 or gcc4.8 (you can choose which one)
• launches a couple of tests on successfully compiled binary

You can look at it here, here and here.

We got an archive with directory "ctf" with only one file "flag.txt" which contains next text:

Nothing to see here, moving along... 

In this task we have a gzip compressed python file which contained rot13-encoded source code. After decoding we got right source code that was simple to understand - there was creation of function with marshal python module and execution it.

Japanese task description, input file name "japcross.txt" and its content clearly showed us that we need to solve a japanese crossword.

We have the photo and need to find a house address where this photo was made.

This is very simple task, but it requires a lot of patience :)

This task is new implementation of python sandbox.
