WebAug 24, 2011 · A dictionary (as used for a dictionary attack) is simply a long list of possible/likely passwords (without their hashes). You can still use such a list to attack a salted password, it just is a lot slower than a rainbow table attack (but still faster than brute-force). – Paŭlo Ebermann Aug 24, 2011 at 17:04 Add a comment 1

WebAttacks are typically categorized based on the action performed by the attacker. An attack, thus, can be passive or active. Passive Attacks The main goal of a passive attack is to obtain unauthorized access to the information. For example, actions such as intercepting and eavesdropping on the communication channel can be regarded as passive attack. WebAttacking a password has cost about t^2/2 hash computations, and t lookups (a "lookup" is when you are actually looking for data in the harddisk). – Thomas Pornin Oct 26, 2011 at 13:00 400 GB is cheap, I can have 5 times that much storage space for 100$.
