DESCRIPTION
Marcus Got a Mysterious mail promising a flag if he could crack the password to the
file

We took the Zip file from the given downloads description of the challenge and I found that the zip
file is locked.

So I tried to crack the zip file using zip2john. And I saved the hashes in the zip file using the
command “zip2john unzipme.zip > zip.hashes”. Now I tried to bruteforcing the hashes file using the
rocyou.txt using the command “john –wordlist=rockyou.txt zip.hashes”. And From that I got the
password of the zip file.

After opening the zip file. I found the flag.
