A rainbow table is an optimized, precomputed lookup table used to trade off CPU processing time for memory storage. Instead of computing every hash on the fly, a rainbow table allows tools to look up the plaintext password of an NTLM hash within seconds, provided the password falls within the table's character length and set parameters. 3. Brute-Force Attacks

Encryption (AES, RSA) requires a key. If you have the key, you run the cipher in reverse. Hashing (MD4, SHA-256) destroys information. Multiple inputs can produce the same hash (collisions), but more importantly, there is no reverse function.

Modern decrypters/crackers utilize hardware acceleration to speed up the guessing process: ntlm-hash-decrypter

Security auditors and penetration testers use specialized, highly optimized software to crack NTLM hashes offline:

The converted string is run through the MD4 hashing algorithm. The result is a 32-character hexadecimal string. The Core Property of Hashing: One-Way Functions

algorithm to a UTF-16LE encoded version of a Windows password. Because NTLM is a "fast" hash without a salt, it is highly susceptible to brute-force dictionary attacks Types of NTLM Hash Decrypters

A free online tool that compares hashes against a massive database of over a billion entries.

A versatile, open-source tool that supports hundreds of hash types and is a staple in the cybersecurity community. Hashing (MD4, SHA-256) destroys information

: Known as the world's fastest password cracker, Hashcat utilizes the processing power of graphics cards (GPUs) to guess billions of combinations per second. It supports highly customizable rule-based attacks.

The output of this MD4 hash is the NTLM hash. This hash is what's stored in the Windows Security Account Manager ( SAM ) database and in Active Directory.
