This challenge involved, as the challenge named hinted at, some sort of password cracking operation to capture the flag. The challenge file was a password protected zip file. I utilized fcrackzip to help me out (Figure 1).
fcrackzip -v -D -u -p ~/wordlists/rockyou.txt misc100
The password was found quickly and easily enough! Unzipping the challenge with the discovered password provided the flag (Figure 2)!
