pass the hash attack tutorial

In my previous post, we learned how to extract password hashes for all domain accounts from the Ntds.dit file.In this post, we're going to see what you can do with those hashes once you have them.

In order to use this payload type set payload windows/shell_reverse_tcp. You get Net-NTLMv1/v2 (a.k.a NTLMv1/v2) hashes when using tools like Responder or Inveigh.

In this article we will look at how this technique works and I will demonstrate the process that can be used to take stolen password hashes and use them successfully without having to crack their hidden contents. This book explains how the operating system works, security risks associated with it, and the overall security architecture of the operating system. NTLM hashes are stored in the Security Account Manager (SAM) database and in Domain Controller's NTDS.dit database. He logs on to his laptop and got a user session, so he has the one hash value of his password stored on the system. Pass the hash is an attack method that attempts to use a looted password hash to authenticate to a remote system. Attack Catalog. This is known as pass the hash attack, where instead of following the time consuming process like crack the password from the NTLM hashes, it can directly pass the hash and allow us to access resources remotely using another user privilege. The remaining chapters discuss how to secure Windows 7, as well as how to troubleshoot it. This book will serve as a reference and guide for those who want to utilize Windows 7. This is a payload that will execute an instance of cmd.exe and shovel it back through our connection so that we can access it remotely. Passing the hash is difficult to detect and prevent due to the nature of how it exploits the authentication process. Cool, now you can go ahead and delete Cain and john because your password cracking days are over? In order to begin you must first launch the Metasploit console.

Over-the-Hash Attack Detection Overpass-the-Hash is a variation on the Pass-the-Hash lateral movement technique in which the attacker passes a user's Kerberos key for authentication . No prior experience is needed. Web apps are a "path of least resistance" that can be exploited to cause the most damage to a system, with the lowest hurdles to overcome. This is a perfect storm for beginning hackers. Harvest NTLM hashes and simulate an Overpass-the-Hash attack to obtain a Kerberos Ticket Granting Ticket (TGT). You can use Responder in combination with a relay tool to automatically intercept connections and relay authentication hashes! You can download BT4 from here. The Metasploit Framework makes discovering, exploiting, and sharing vulnerabilities quick and relatively painless. But while Metasploit is used by security professionals everywhere, the tool can be hard to grasp for first-time users. The only caveat to this attack? In order to use this module and payload there are a few options we have to configure.

Pass-the-Hash is a technique that enables an attacker (typically using Mimikatz) to leverage the LanMan or NTLM hashes of a user's password to authenticate to a directory or resource.

This would be known as kerberoasting. What's really cool about this? These techniques should only be used for legitimate and legal purposes, i.e. SMBv2 Signing enabled but not required. A user is allowed to request a ticket-granting service (TGS) ticket for any SPN, and parts of the TGS may be encrypted with the with RC4 using the password hash of the service account assigned the requested SPN as the .

Basically, this is a combination of both attacks. By using the -local-auth and a found local admin password this can be used to login to a whole subnets smb enabled machines with that local admin pass/hash. Typically, you would supply a username and password. "Managing Windows security has always been a challenge for any security professional. Dictionaries of common passwords can be used, which can help expedite cracking when common or weak passwords are used. Steps. This attack method makes it very easy to compromise other machines that share the same credentials. Pass the hash is a post-compromise technique for further credential theft and lateral movement. If Kerberoasting is detected, there are several response actions that should be taken: MITRE ATT&CK and ATT&CK are registered trademarks of The MITRE Corporation, #Build LDAP Filter to look for users
