Brute Force Attack Definition
A brute force attack is a hacking method that uses trial and error to crack
passwords, login credentials, and encryption keys. Attackers try multiple
combinations until they find the correct login information. There are different
types of brute force attacks:
1. Simple Brute Force Attacks: Hackers manually guess passwords using
common combinations or personal information.
2. Dictionary Attacks: Attackers test possible passwords against a
username, using dictionaries and adding special characters.
3. Hybrid Brute Force Attacks: Combines dictionary attacks with simple
brute force methods to discover login combinations.
4. Reverse Brute Force Attacks: Attackers start with a known password and
search for matching usernames.
5. Credential Stuffing: Attackers use stolen username/password
combinations on other websites.
The motives behind brute force attacks include exploiting ads or activity data,
stealing personal data, spreading malware, hijacking systems for malicious
activity, and damaging a company's reputation.
Hackers use various tools for brute force attacks, such as password-cracking
applications like Aircrack-ng and John the Ripper.
To prevent brute force attacks, individuals and organizations can use stronger
passwords, including complex passphrases, unique passwords for each
account, and password managers. Organizations should also encrypt
passwords and strengthen network security.
