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.

• 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.

• Reverse brute-force attacks It is a form of
  brute-force attack in which an attacker attempts
  to obtain access to a network by using a common
  password against many accounts.
• Password spraying In this, an attacker will use
  a list of usernames and default passwords on the
  application to brute force logins.
• Rainbow table attack It is a method of cracking
  password hashes in a database by using a
  particular table known as a rainbow table.
• The motive behind brute-force attack
• Brute-force attacks can be used to steal
  sensitive information and infiltrate computers
  for nefarious reasons. Attackers can disable
  websites, profit from advertisements, redirect
  traffic to commissioned advertisement sites, and
  infect websites with spyware.
