Using Hashcat involves several steps, and it requires familiarity with the command-line interface.

Below is a general guide on how to use Hashcat for password cracking:

Prerequisites:

1. Install Hashcat:

- Download the latest version of Hashcat.

- Extract the downloaded file to the desired location.

2. Gather Hashes:

- Obtain the hash values you want to crack. These can be from password files, databases, or other sources.

Basic Usage:

1. Choose Attack Mode:

- Hashcat supports various attack modes. Common ones include:

- Straight: Traditional brute-force attack.

- Dictionary: Uses a wordlist or dictionary file.

- Hybrid: Combines a dictionary with brute-force or mask attacks.

- Brute-force: Tries all possible combinations.

2. Select Hash Type:

- Specify the hash algorithm used in the target hashes (e.g., MD5, SHA-256).

3. Prepare Wordlists:

- For dictionary attacks, you need a wordlist. Hashcat supports custom and pre-existing wordlists.

4. Run Hashcat:

- Open a command prompt or terminal window.

- Navigate to the Hashcat directory.

5. Construct Command:

- Build the Hashcat command, specifying the attack mode, hash type, wordlist, and other parameters.

- Example Command: `hashcat -m 0 -a 0 hashes.txt wordlist.txt`

6. Start the Attack:

- Execute the command to begin the password cracking process.

- Hashcat will display progress and any recovered passwords.

Advanced Features:

1. Rules:

- Hashcat supports rules to modify wordlists and enhance the chances of success. Use the `-r` option to specify a rule file.

2. Mask Attacks:

- For brute-force attacks, you can define a mask to guide the search. Use the `-a 3` option and specify the mask.

3. Performance Tuning:

- Hashcat has options for tuning performance automatically (`--optimize`) or manually (`-w` for workload profile).

4. Pause and Resume:

- Hashcat supports interactive pause and resume using the `--restore` option.

5. Benchmarking:

- Evaluate your system's performance with benchmarking using the `-b` option.

Example Commands:

- Dictionary Attack:

hashcat -m 0 -a 0 hashes.txt wordlist.txt

- Brute-force Attack with Mask:

hashcat -m 0 -a 3 hashes.txt ?d?d?d?d?d?d

- Hybrid Attack:

hashcat -m 0 -a 6 hashes.txt wordlist.txt ?d?d?d?d?d?d

Notes:

- Replace `hashes.txt` with the path to your hash file.

- Adjust hash mode (`-m`) and attack mode (`-a`) based on your specific needs.

- Refer to Hashcat documentation for a comprehensive list of options and advanced features.
