PicoCTF_2017: Leaf of the Forest

Category: Miscellanous Points: 30 Description:

We found an even bigger directory tree hiding a flag starting at /problems/7d91c03dff81a9c95bffb6d69358c92d. It would be impossible to find the file named flag manually...

Hint:

Is there a search function in Linux? Like if I wanted to 'find' something...

Write-up

Well, apparently the solution for the previous challenge is used for this one. So, lets find the flag!

$ find /problems/7d91c03dff81a9c95bffb6d69358c92d/ -type f -name flag -exec cat {} \;
7ffb59b2f309c09959ba333d0af88565

Easy! Therefore, the flag is 7ffb59b2f309c09959ba333d0af88565.
