Ntlm Decode -

Attackers use tools like or John the Ripper . They feed the tool the hash and a wordlist (like rockyou.txt ). The tool iterates through the list, hashing each word, until it finds a match.

The client tells the server it wants to authenticate using NTLM.

When you decode the binary structure of these messages (specifically Type 3), you can extract information . This is because the protocol sends certain user details in cleartext to facilitate the connection.

NTLM decoding refers to the process of extracting the password hash from the NTLM response. This can be useful for various purposes, such as: Attackers use tools like or John the Ripper

Enter the user's plaintext password in the "NT Password" field.

But what does "decode NTLM" actually mean? The client tells the server it wants to

The more common use of the phrase "NTLM decode" refers to recovering a password from an .

Interestingly, in many Windows environments, you don't even need to decode the hash to gain access. Since the hash itself is effectively the password proof, attackers can use the stolen hash directly to authenticate to other systems on the network without ever knowing the actual plaintext password.

If you have captured a network session, the data payloads (like files sent via SMB) are often encrypted using keys derived from the NTLM exchange. To decode this "encrypted stub data" in Wireshark :
