Is NTLMv2 vulnerable to pass the hash?
NTLM has been succeeded by NTLMv2, which is a hardened version of the original NTLM protocol. NTLMv2 includes a time-based response,which makes simple pass the hash attacks impossible.
What is an SMB relay attack?
SMB Relay Attack is a type of attack which relies on NTLM Version 2 authentication that is normally used in most companies. Unfortunately, when we are listening to what is going on in the network, we're able to capture a certain part of the traffic related to the authentication and also relay it to the other servers.
Can you relay NTLMv2 hashes?
NetNTLM hashes can only be utilized for relaying attacks or for potential brute-forcing using Hashcat, for example. Another pro tip is that NTLMv2 hashes are harder to crack than their NTLMv1 counterpart but not impossible for user accounts!
Can you pass the hash with NTLMv1?
Authentication protocols, NTLMv1 and NTLMv2 in particular, do not pass NT hashes on the network, but rather pass values derived from the NT hashes, called NTLMv1 and NTLMv2 hashes, respectively. Windows 10 environments do not support by default NTLMv1 (Shamir, 2018).
