Description. This module forges NetBIOS Name Service (NBNS) responses. It will listen for NBNS requests sent to the local subnet's broadcast address and spoof a response, redirecting the querying machine to an IP of the attacker's choosing. This hashed password can then be cracked offline, and if successful, it will reveal the user’s password in cleartext. Additionally, the Web Proxy Auto-Discovery (WPAD) protocol will broadcast a message (likely using LLMNR or NBNS) looking for the “WPAD” server if the DNS query for that server fails, which can be poisoned in the same manner.

NetBIOS and NetBEUI are separate but related technologies.
The discovery is mDNS, exactly same as Apple TV bonjour protocol. Reflector can be installed on most popular entertainment devices like. By default mDNS does not flow between VLANs, so in order to make discovery of these devices possible once they are in a seperate VLAN, the Unifi mDNS Reflector needs to be enabled on the controller. The core issue is that systems will send out requests for hostnames that are not configured in DNS. This creates an opportunity for mitm. With LLMNR/NBNS enabled, these requests fall down to LLMNR/NBNS after trying DNS. With LLMNR/NBNS disabled, the requests will still try DNS. Since this attack leverages DNS, it will still work.
