Where possible, disable NTLM and use Kerberos , which is more secure and supports modern encryption standards.
In modern cryptography, a "salt" is a random string added to a password before hashing to ensure that two users with the same password have different hashes. Because NTLM lacks salting, the hash for "Password123" is identical on every Windows machine in the world. This makes NTLM highly susceptible to attacks and rainbow table lookups. Online vs. Offline Decrypters
The NTLM hash is specifically an MD4-based hash of the user's password. Because hashing is a one-way function, the system compares the hash of the password you just typed with the hash stored in the database or the Active Directory (NTDS.dit) file. If they match, access is granted. How an NTLM Hash "Decrypter" Actually Works ntlm-hash-decrypter
NTLM Hash Decrypter: Understanding and Securing Windows Authentication
Tools like John the Ripper or Hashcat run on your local hardware. They offer more control and privacy but require significant processing power for complex passwords. How to Protect Your Environment Where possible, disable NTLM and use Kerberos ,
Use security tools to identify where NTLM is still being used in your network and work toward deprecating it. Conclusion
When you log into a Windows machine, the operating system does not store your plaintext password. Instead, it converts the password into a cryptographic representation called a . This makes NTLM highly susceptible to attacks and
Modern tools like leverage the power of Graphics Processing Units (GPUs) rather than CPUs. A high-end GPU can attempt billions of NTLM hashes per second, making short work of simple or medium-complexity passwords. Why NTLM is Vulnerable
