Note the rockyou wordlist has more than 14 million words which are the most frequently used passwords sorted by frequency.Īlright, we have successfully built a simple but useful script that cracks the zip file password, try to use much more bigger wordlists if you failed to crack it using this list.įinally, I highly encourage you to use multiple threads for cracking the password much faster, if you succeed to do so, please share your results with us in the comments below ! Here is your challenge Total passwords to test: 14344395 3 %|▉ | 435977/ 14344395 Īs you can see, I have found the password after around 435K trials, which took about a minute in my machine. Results :~ # gunzip :~ # python3 zip_cracker.py secret.zip /usr/share/wordlists/rockyou.txt The method extractall() will raise an exception whenever the password is incorrect, so we can pass to the next password in that case, otherwise, we print the correct password and exit out of the program.

We open the wordlist and read it word by word and tries it as a password to extract the zip file, reading the entire line will come with the new line character, as a result, we use the strip() method to remove white spaces. Since wordlist now is a Python generator, using tqdm won't give much progress information, that's why I introduced the total paremeter to give tqdm the insight on how many words are in the file. Print( " Password not found, try other wordlist.") Print( " Password found:", code().strip()) Notice we read the entire wordlist and then get only the number of passwords to test, this can prove useful for tqdm so we can track where we are in the brute forcing process, here is the rest of the code: with open(wordlist, "rb") as wordlist:įor word in tqdm(wordlist, total=n_words, unit= "word"): Print( "Total passwords to test:", n_words) N_words = len(list(open(wordlist, "rb"))) # count the number of words in this wordlist To read the zip file in Python, we use the zipfile.ZipFile class that has methods to open, read, write, close, list and extract zip files (we will only use extractall() method here # initialize the Zip File object Wordlist = "rockyou.txt" # the zip file you want to crack its password Let's specify our target zip file along with the word list path: # the password list path you want to use, must be available in the current directory You can also use crunch tool to generate your custom wordlist as you exactly specify.Įnough talking, let's now jump into the part we want. For this tutorial, we are going to use the big rockyou wordlist (with the size of about 133MB), if you're on Kali Linux, you can find it under the /usr/share/wordlists/ path.

We will be using Python's built-in zipfile module, and the third-party tqdm library for quickly printing progress bars: pip3 install tqdmĪs I have mention, we are going use dictionary attack, which means we need a wordlist to brute force this password-protected zip file. In this tutorial, you will write a simple, but yet precise Python script that tries to crack a zip file's password using dictionary attack.

Say you're tasked to investigate a suspect's computer and you find a zip file that seems very useful but protected with a password.
