Specifically, we’ll be discussing how to use oclHashcat-plus to make your password cracking dreams come true.
Now, before you start throwing tomatoes at me for promoting such a nefarious activity, lets just say that this is all in the name of research and education (and maybe a little bit of fun). After all, if we don’t learn how to break into things, how can we possibly hope to secure them?
So without further ado, let’s dive right in!
First off, youll need to download oclHashcat-plus from their website. Don’t worry, it’s totally legal and free (as long as you don’t use it for nefarious purposes). Once you have the software installed on your Linux machine, let’s get started with cracking some passwords!
Step 1: Gather Your Wordlists
The first thing youll need is a wordlist. This can be any list of words or phrases that might contain potential passwords (think dictionary words, common names, etc.). You can find plenty of free wordlists online, but just make sure they’re not too old and haven’t been compromised already!
Step 2: Prepare Your Hashes
Next, youll need to prepare your hashed passwords. This involves running them through a hash function (such as MD5 or SHA1) so that they can be compared against the wordlist in step one. There are plenty of tools out there for doing this, but we recommend using John the Ripper (which is also free and open source).
Step 3: Launch oclHashcat-plus
Now it’s time to launch oclHashcat-plus! This can be done by running the following command in your terminal:
#!/bin/bash # This line specifies the interpreter to be used for executing the script
# Step 1: Install oclHashcat-plus
# This step is not included in the script, but it is necessary to install oclHashcat-plus before running the script.
# Step 2: Create a wordlist
# This step is not included in the script, but it is necessary to have a wordlist before running the script.
# Step 3: Launch oclHashcat-plus
# This step is where the script starts. The following line executes the oclHashcat64.bin file, which is the executable for oclHashcat-plus.
# The -m 100 flag specifies the hash type to be cracked.
# The hashfile is the file containing the hashes to be cracked.
# The wordlist is the file containing the list of words to be used for cracking.
# The -o flag specifies the output file where the cracked hashes will be saved.
# The --remove flag removes the cracked hashes from the hashfile.
./oclHashcat64.bin -m 100 hashfile wordlist -o outputfile --remove
This will run a brute force attack against the hashed passwords using oclHashcat-plus’ GPU acceleration (which is much faster than CPU-based cracking). The `-m 100` flag specifies that were using SHA1 as our hash function, and the `–remove` option tells oclHashcat-plus to remove any duplicate passwords from the output file.
Step 4: Sit Back and Watch the Magic Happen!
That’s it! Now just sit back and watch as oclHashcat-plus cracks your hashed passwords faster than you can say “password security is important” (which, lets face it, isn’t very fast). And if you want to speed things up even more, you can try using John the Ripper to preprocess your wordlist before running oclHashcat-plus. This involves adding rules and masks to your wordlist so that oclHashcat-plus can crack passwords with special characters or numbers.
