How does a rainbow table help an 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. But in essence, it's just a dictionary. When an attacker steals a long list of password hashes from you, he can quickly check if any of them are in the Rainbow Table.
