It can be executed in different ways, for example, by using a framework such as Metasploit or CobaltStrike, or simply using standalone scripts. Mimikatz is a classical tool used within the offensive vertice of cybersecurity, with the goal of getting clear-text passwords and hashes from memory. On the other hand, if an NTLM hash is retrieved, it can be directly used via a Pass-the-Hash attack on the target, obtaining valid access. In the next step, the hash can be brute-forced using john the ripper or hashcat tools.Īfter this point, lateral movement or simply accessing target machines is possible with the cracked hash account. ![]() ![]() By using the Responder tool, we can get a valid hash for the user: Charlie\John as demonstrated below. Experts take advantage of LLMNR and NBT-NS protocols in an internal network to poison and relay authentication requests on the network and get the users’ hashes or simply a valid connection with a single machine within the context of the users’ session.Ī set of tools can be used to reproduce this technique, such as NBNSpoof, Metasploit and Responder.
