A rainbow table attack is an method for cracking passwords that makes use of a unique table to crack database password hashes. Attackers often use dictionary words or password dumps from data breaches to target the most likely and often used passwords when generating rainbow tables.In a rainbow table attack, the attacker locates the plaintext version of a hashed password using a precomputed hash table.Systems without two-factor authentication (2FA) are also targeted by attackers. Rainbow table attacks focus on particular system types that are especially susceptible due to particular attributes.Users should use strong passwords to avoid rainbow table attacks.Usually, a strong password consists of a combination of special characters, digits, and capital and lowercase letters. Password salting is an unique method to prevent rainbow table attack.A random piece of information is added to the password before it is processed by the password hashing method, a process known as password salting.Rainbow table attacks can be effectively prevented by using two-factor authentication, rate limitation, and account lockout measures.
