The working principle and attack mode of hashcat

What is a Hashcat?

Hashcat is a leading global high-performance hash cracking tool. It is known for its open source, flexibility, and high speed, and is widely used in fields such as password recovery, penetration testing, and information security research. Hashcat supports multiple cracking algorithms and attack modes, enabling it to design optimal cracking paths for different hash structures.

Understanding how Hashcat works and various attack modes will greatly improve cracking efficiency and success rate.

How Hashcat Works

The basic principle of Hashcat can be summarized as follows:

1. Load the hash target: i.e., the encrypted string that needs to be cracked;

2. Generate candidate passwords : generate possible plaintext passwords through various strategies;

3. hash the candidate password: use the same hash algorithm as the target;

4. Comparison result: If the calculated hash value matches the target, the cracking is successful.

Hashcat makes full use of the parallel computing power of the GPU, enabling it to process billions of hash calculations per second, far exceeding traditional CPU cracking methods.

Common Hashcat Attack Patterns

1. A Dictionary Attack

uses an off-the-shelf list of passwords (dictionaries) as a candidate password source. Suitable for users with weak or common passwords.

Command example:

 bash copy edit hashcat -m 0 -a 0 hash.txt wordlist.txt

2. A Combinator Attack

combines words from two dictionaries in pairs to generate a new candidate password. Suitable for simple password combinations (such as summer2024).

Command example:

bash copy edit hashcat -m 0 -a 1 hash.txt dict1.txt dict2.txt

3. Mask attacks

define their own password structure, such as length and character type, and are suitable for situations where the password pattern is known but the specific content is unknown (e.g., six digits).

Command example:

bash copy edit hashcat -m 0 -a 3 hash.txt ? d? d? d? d? d? d

4. Rule-Based attacks

Based on dictionary attacks, candidate passwords are changed according to rules, such as adding numbers and changing case. Suitable for complex but regular passwords.

Command example:

bash copy edit hashcat -m 0 -a 0 hash.txt wordlist.txt -r rules/best64.rule

5. Brute-Force Attack

exhausts all possible password combinations and is suitable for scenarios where the password is extremely short or there is no other option, but it is computationally intensive.

Command example:

bash copy edit hashcat -m 0 -a 3 hash.txt ? And? And? And? A
