Rainbow table attacks don't work against biometric passwords, which verify a user's identity. Rainbow table attacks work under the assumption that a text string has one specific hash value the extra generated characters change that expected hash value.

Salting.This technique adds a random string of characters to passwords before encrypting them.

To protect against attacks using rainbow tables, systems administrators should add these security measures:

Rainbow attacks are much less common due to the use of modern cryptographic hash functions, namely salted passwords.

If the hash the attacker is trying to break isn't in the table, the attack becomes much less viable.

They require a large amount of storage to make the attack completable in a realistic amount of time.

Authentication is possible as long as the hash matches.ĭisadvantages of rainbow tables include the following:

The exact password doesn't need to be known.The process is simplified as a search-and-compare operation, as all of the values in a rainbow table should already be computed.

They make password cracking much faster than earlier methods, such as brute-force attacks and dictionary attacks.Rainbow tables provide the following advantages:

With the correct hash, the threat actor can now successfully access the device - they've cracked the authentication process. If there's a match, the plaintext that produced the hash is retrieved and the process is stopped. The plaintext passwords are then stored in the table next to their hashes.Ī password-cracking program then compares the rainbow table's list of potential hashes to hashed passwords in the database.

To crack a password, or for rainbow table attacks, large numbers of hashes are run through a dataset and then through multiple reduction stages to split them into smaller components that are linked to plaintext characters. If the hashes match, then the user is authenticated. The result is compared with the stored hashes to look for a match.

After a user enters a password, that password is converted into hashes. Hash functions transform any given string of characters into another value. Instead, they are encrypted using hashes. Passwords aren't typically saved as plain, readable text or plaintext. With each reduction function being a different color, the final plaintexts and hashes would look like a rainbow. Rainbow refers to the different colors used in the table to show the various hashing and reduction functions and steps. Although rainbow tables provide security administrators with a method to test password security standards, they also provide hackers a way to quickly crack passwords and gain unauthorized access to computer systems. Gillis, Technical Writer and EditorĪ rainbow table is a password hacking tool that uses a precomputed table of reversed password hashes to crack passwords in a database.
