Crack Nt Hash Windows 7
In my prior article, “” we looked at how safe Windows LM based passwords were. But what about NTLM based Passwords?Windows systems usually store the NTLM hash right along with LM hash, the NT hash being more secure. What many readers wanted to know is how much longer would it take to access the user account, if only the NTLM hash was available?This is a great question, and the answer is, if certain circumstances are met and a certain technique is used, it could take the same amount of time. Even more shocking is the fact that it may actually be quicker.Let me explain, if you can retrieve the LM or NT hashes from a computer, you do not need to crack them. There is really no need.Sometimes you can simply take the hash as-is and use it as a token to access the system.

This technique is called “Pass the Hash”.Several programs exist that perform “Pass the Hash” type attacks. In this example I used the “Pass the Hash” capability of Backtrack 4.What is nice about this is that once you retrieve the hash, you can copy the hash and place it right into Backtrack 4’s “Pass the Hash” routine.I will not show the step by step process, but will show you the passwords used and the outcome. The password hashes are taken from an updated Windows XP SP3 system and a Windows 7 system.Without further ado, let’s see this in action.First we will try feeding the XP hash for the 17 character password%P”mAn open session with the PC and a remote shell. Looks like it workedNow let’s try the same 17 character complex password on the Windows 7 PC.Placing the Windows 7 hash into the program, we get this:Process 3392 created.Channel 1 created.Microsoft Windows Version 6.1.7600Copyright © 2009 Microsoft Corporation. All Rights reserved.C:WINDOWSsystem32A Windows 7 remote shell. Wow, that worked too.Let’s try one last one:Long pass phrases with multiple words are more secure right?Password: TheQuickBrownFoxJumpsOverTheLazyD0g!And the results?
A Windows 7 command prompt.Does the password length make any difference at all? Using this technique the answer is no. The password length or complexity made no discernable difference at all, because we are just passing the hash as-is and not cracking it.What can be done to prevent this type of attack?
HashKiller.co.uk is a hash lookup service. NT (New Technology) LAN Manager (NTLM) is a suite of Microsoft security protocols that provides authentication, integrity, and confidentiality to users. NTLM is the successor to the authentication protocol in Microsoft LAN Manager (LANMAN), an older Microsoft product. The NTLM protocol suite is implemented in a Security Support Provider, which combines the LAN Manager authentication protocol, NTLMv1, NTLMv2 and NTLM2 Session protocols in a single package. Whether these protocols are used or can be used on a system is governed by Group Policy settings, for which different versions of Windows have different default settings. NTLM passwords are considered weak because they can be brute-forced very easily with modern hardware.
