When a host in the network sent a NetBIOS broadcast the machine of the attacker will sent a fake reply and the host will attempt to authenticate to a resource using the NTLM password hash.
What is LLMNR NBNS?
Both NetBIOS Name Server and Local-Link Multicast Name Resolution (NBNS and LLMNR) are protocols that a Windows computer uses to look for a host on the internal network when a host’s IP address cannot be resolved through the organizational DNS (Domain Name Server) server.
What is LLMNR spoofing?
Adversaries can spoof an authoritative source for name resolution on a victim network by responding to LLMNR (UDP 5355)/NBT-NS (UDP 137) traffic as if they know the identity of the requested host, effectively poisoning the service so that the victims will communicate with the adversary controlled system.

What are the advantages and disadvantages of adidns spoofing over LLMNR/NBNS?
The major advantage of ADIDNS spoofing over LLMNR/NBNS spoofing is the extended reach and the major disadvantage is the required AD access. Let’s face it though, we don’t necessarily need a better LLMNR/NBNS spoofer. Looking back, NBNS spoofing was a security problem long before LLMNR joined the game.
