SHA2017 - Junior CTF - Zipfile Two - Misc

Problem

We received another zip file, which also requires a password. All we know is that the password is an existing English word with a length of 6 and all lowercase. Can you crack this password?

zipfiletwo.zip 72bac30689c07b30cf9a4c6f74bcbdd9

Solution

This challenge is of similar complexity as Zipfile One requiring a brute force attack.

$ fcrackzip -v -D -u -p rockyou.txt zipfiletwo.zip

The password is future and unzipping returns the flag.
