What is Hashcat?
Hashcat is the world's leading high-performance hash cracking tool, which is known for its open source, flexibility, and high speed, and is widely used in password recovery, penetration testing, information security research, and other fields. Hashcat supports a variety of cracking algorithms and attack modes, and can design the optimal cracking path for different hash structures.
Understanding how Hashcat works and the various attack patterns will greatly improve the efficiency and success rate of cracking.
How Hashcat works
The basic principles of Hashcat can be summarized as:
Load the hash target: that is, the encrypted string that needs to be cracked;
Generate candidate passwords: generate possible plaintext passwords through various strategies;
Hash the candidate password: use the same hashing algorithm as the target;
Comparison result: If the calculated hash value matches the target, the crack is successful.
Hashcat takes full advantage of the parallel computing power of GPUs, allowing it to process billions of hashes per second, far exceeding traditional CPU cracking methods.
Hashcat common attack patterns
1. Dictionary Attack
Use an out-of-the-box password list (dictionary) as a candidate password source. It is suitable for when the user's password is weak or common.
Example command:
bash复制编辑hashcat -m 0 -a 0 hash.txt wordlist.txt
2. Combinator Attack
Combine words from two dictionaries in pairs to generate a new candidate password. Suitable for simple combination passwords (e.g. summer2024).
Example command:
bash复制编辑hashcat -m 0 -a 1 hash.txt dict1.txt dict2.txt
3. Mask Attack
Define your own password structure, such as length and character type, for situations where you know the password pattern but don't know the exact content (e.g., six digits).
Example command:
bash复制编辑hashcat -m 0 -a 3 hash.txt ?d?d?d?d?d?d
4. Rule-Based Attack
Based on dictionary attacks, candidate passwords are changed according to rules, such as adding numbers and changing capitalization. Ideal for complex but regular passwords.
Example command:
bash复制编辑hashcat -m 0 -a 0 hash.txt wordlist.txt -r rules/best64.rule
5. Brute-Force Attack
Exhaustively enumerating all possible password combinations, suitable for scenarios where passwords are extremely short or have no alternative, but the computation is huge.
Example command:
bash复制编辑hashcat -m 0 -a 3 hash.txt ?a?a?a?a
Why choose to run Hashcat online?
If you want to really get the most out of Hashcat, you'll need strong hardware, especially the latest generation of GPUs like the RTX 5090.
