Original description
It's Friday the 13th at Camp grinsby.
A flag was discovered near the boathouse, but something feels off.
The real secret is locked away inside the cabin by a strange curse.
This challenge focuses on Linux file and directory permissions.
Instructions:
> Download the archive
> Extract it on a Linux system
> Explore the files and directories
> Fix the broken permissions to reach the real flag
Notes:
> Not everything that looks readable is accessible
> Directories have permissions too
> The first flag you find may not be the real one
