Naive Hashcat

Crack password hashes without the fuss. Naive hashcat is a plug-and-play script that is pre-configured with naive, emperically-tested, "good enough" parameters/attack types. Run hashcat attacks using ./naive-hashcat.sh without having to know what is going on "under the hood".

Getting started

git clone https://github.com/brannondorsey/naive-hashcat
cd naive-hashcat

# if you are on MacOS/OSX, run this. If on linux or windows, skip...
./build-hashcat-osx.sh

# download the 134MB rockyou dictionary file
curl -L -o dicts/rockyou.txt https://github.com/brannondorsey/naive-hashcat/releases/download/data/rockyou.txt

# cracks md5 hashes in hashcat-3.6.0/example0.hash by default
./naive-hashcat.sh

What it do?

./naive-hashcat.sh assumes that you have hashed passwords that you would like to know the plaintext equivalent of. Likely, you've come across a text file that contains leaked accounts/emails/usernames matched with a cryptographic hash of a corresponding password. Esentially something that looks like:

(⬆⬆⬆ not real hashes btw, don't get any ideas...)

If you don't have such a file, pastebin.com is a popular text paste site that black-hat hackers love posting leaked account credentials to. And lucky 4 u, they have a trending feature that makes "interesting content" bubble to the top. If you can't find leaked creds atm, I've written a tool that archives trending pastes each hour.

Once you've got some hashes, save them to a file with one hash per line. For example, hashes.txt:

01e870ebb01160f881ffaa6764acd01f
f15a413c1835014679a286ee84a212d4

To crack your hashes, pass this file as HASH_FILE=hashes.txt to the command below.

Usage

naive-hashcat.sh takes, at most, three parameters. All parameters are expressed using unix environment variables. The command below shows the default values set for each of the configurable environment variables that naive-hashcat.sh uses:

HASH_FILE=hashcat-3.6.0/examples0.hash POT_FILE=hashcat.pot HASH_TYPE=0 ./naive-hashcat.sh

• HASH_FILE is a text file with one hash per line. These are the password hashes to be cracked.
• POT_FILE is the name of the output file that hashcat will write cracked password hashes to.
• HASH_TYPE is the hash-type code. It describes the type of hash to be cracked. 0 is md5. See the Hash types section below for a full list of hash type codes.

What naive-hashcat does

naive-hashcat.sh includes a small variety of dictionary, combination, rule-based, and mask (brute-force) attacks. If that sounds overwhelming, don't worry about it! The point of naive hashcat is that you don't have to know how it works. In this case, ignorance is bliss! In fact, I barely know what I'm doing here. The attacks I chose for naive-hashcat.sh are very naive, one-size-kinda-fits-all solutions. If you are having trouble cracking your hashes, I suggest checking out the awesome hashcat wiki, and using the hashcat tool directly.

At the time of this writing, naive-hashcat cracks ~60% of the hashes in examples0.hash.

Ok, I think its working... what do I do now?

So you've run ./naive-hashcat.sh on your HASH_FILE, and you see some passwords printing to the screen. These hash:password pairs are saved to the POT_FILE (hashcat.pot by default). Now you need to match the hashes from the original file you... um... found (the with lines like [email protected]:01e870ebb01160f881ffaa6764acd01f) to the hash:password pairs in your pot file.

Run python match-creds.py --accounts original_file.txt --potfile hashcat.pot > creds.txt to do just that! This tool matches usernames/emails in original_file.txt with their corresponding cracked passwords in hashcat.pot and prints username:password:

[email protected]:Password1
[email protected]:Qwerty1234
[email protected]:PleaseForHeavenSakeUseAPasswordManager

Congratulations, you just hacked the private passwords/account information of many poor souls. And because everyone still uses the same password for everything you likely have the "master" password to tons of accounts.

And remember

1. use a password manager
2. don't pwn people
3. don't go to jail

‍ Happy hacking ☠

P.S. ./naive-hashcat.sh can take anywhere from a few minutes to a few hours to terminate depending on your hardware. It will constantly stream results to the POT_FILE, and you are free to use the contents of that file for further processing with match-creds.py before cracking is finished.

GPU Cracking

Hashcat ships with OpenCL and runs on available GPU hardware automatically when available.

Hash types

Below is a list of hash-type codes supported by hashcat. If you don't know the type of hash you have, you can use hashid to try and identify it. Include the appropriate hash-type using the HASH_TYPE environment variable.
