fcrackzip (Note: fcrackzip is not preinstalled on Kali) that allow us to brute force zip files. The syntax is as follows

fcrackzip -b --method 2 -D -p /usr/share/wordlists/rockyou.txt -v ./file.zip

-b specifies brute forcing, --method 2 specifies a Zip file, -D specifies a Dictionary and -V verifies the password is indeed correct.

Reading the contents of the file, we can see it is just a standard text file with several items. Not everything you find will always be malicious!
