How I Cracked a Password‑Protected Cain & Abel Zip in 5 Hours with John the Ripper

The author was studying networking and needed the Cain & Abel tool, but the original website was offline, so only community‑provided download packages were available. The downloaded zip archive was password‑protected, prompting the author to try cracking it as a security hobby.

Using Kali Linux, the author ran zip2john to extract a hash from the zip file and saved it to pswd.txt: zip2john cain.zip >> pswd.txt Then the author launched John the Ripper to perform a dictionary/brute‑force attack against the hash: john pswd.txt John uses the built‑in password.lst wordlist for collision detection. The process was left running overnight, and the next day the password was recovered: darknet123 . Extraction of the zip succeeded after about five hours.

Earlier the author had already obtained an unencrypted version of Cain & Abel purely for fun. The author notes that while many consider simple numeric passwords trivial to crack, a mixed alphanumeric password like "darknet123" can still be broken with enough effort, emphasizing the importance of using unique, complex passwords with personal markers and symbols.

This short write‑up serves as a practical example for security enthusiasts who want to experiment with real‑world password cracking.
