Have you ever attempted to guess a friend's Instagram or Facebook password to gain access to their account? If you answered yes, you might have tried a variety of username and password combinations to obtain access to their account, including letters, special characters, and more. However, a human cannot crack the password by trying more than 100 possibilities at once. This is similar to a brute-force attack, except it uses software to automate these procedures. Let us dive deeper into what a brute-force attack is, in this blog.<br><br>

What is a brute-force attack? • A brute-force attack is a type of cyberattack in which a cybercriminal uses a trial-and-error approach to guess all conceivable passwords, encryption keys, or login information combinations to gain unauthorized access to sensitive data and systems. It uses computer software to automate guessing the username and password combinations. • Types of brute-force attacks: • The following are the various types of brute force attacks: • Simple brute-force attacks: It occurs when a cybercriminal manually attempts to guess a user's login credentials without the aid of software. • Dictionary attacks: In this attack, a cybercriminal uses a dictionary list of popular terms and phrases individuals or organizations use, to crack a password-protected security system. • Hybrid brute-force attacks: In this, attackers experiment with combinations of common words and random letters by combining the techniques used in dictionary attacks and simple brute force attacks. • Credential stuffing: The attacker uses stolen credentials in this type of attack. The attacker uses the stolen username and password pairs and injects them into website login forms to illegally acquire access to user accounts. www.infosectrain.com | sales@infosectrain.com
