naive-hashcat: Crack password hashes without the fuss

Naive Hashcat

Crack password hashes without the fuss. Naive hashcat is a plug-and-play script that is pre-configured with naive, empirically-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, 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 does 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. Essentially something that looks like:

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.shuse:

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.
