Description
There's an interesting script in the user's home directory
The work computer is running SSH. We've been given a script which performs some basic calculations, explore the script and find a flag.
Hostname: saturn.picoctf.net
Port: //port number given to you
Username: picoplayer
Password: password
Note: This challenge launches an instance on demand.
That was a tricky challenge, in the home directory there is a file named useless
that does command line arithmetic, spoiler, it does nothing.
The interesting thing to notice was the code itself, specifically the line:
else echo "Read the manual"
Using man
on the script we get the flag hidden at the bottom of the page.
picoCTF{your flag}
