NetBIOS Response "BadTunnel" Brute Force Spoof (NAT Tunnel)

This module listens for a NetBIOS name request and then continuously spams NetBIOS responses to a target for given hostname, causing the target to cache a malicious address for this name. On high-speed networks, the PPSRATE value should be increased to speed up this attack. As an example, a value...
