Description:
In this zip file I store the flag. But I forgot the password. Do you crack it?
Solution:
I tried John to bruteforce the password.
$ zip2john Forgotten.zip > zip_hash.txt
$ john --wordlist=/usr/share/wordlists/rockyou.txt zip_hash.txt
Now I have cracked password “jerry”. After successfully unzipping the file, we discovered a flag.txt file inside. Upon opening it, we found a cipher that was encrypted in Base45. After decrypting the cipher, we finally obtained the flag.
