WebFeb 8, 2024 · Unlike a dictionary attack, where the attacker tries every word in the dictionary until they find a match, a rainbow table attack allows the attacker to quickly find the plaintext password if it exists in the precomputed table. Rainbow tables attacks require less computing power and are much faster than standard dictionary attacks, but they ... WebNow, what the attackers can do is to simply generate a list of common passwords and their corresponding hashes. Comparing the hashes that a site has stored with the table will, if common passwords are being used, reveal the passwords to the attacker.
WebAug 30, 2014 · The Rainbow table is optimized for hashes and passwords, and thus achieves great space optimization while still maintaining good look-up speed.
