NBName (note capitalization) is a
computer program that can be used to carry out
denial-of-service attacks that can disable NetBIOS services on
Windows machines. It was written by
Sir Dystic of
CULT OF THE DEAD COW (cDc) and released July 29, 2000 at the
DEF CON
DEF CON (also written as DEFCON, Defcon or DC) is a hacker convention held annually in Las Vegas, Nevada. The first DEF CON took place in June 1993 and today many attendees at DEF CON include computer security professionals, journalists, lawyer ...
8 convention in
Las Vegas.
The program decodes and provides the user with all NetBIOS name packets it receives on
UDP port 137. Its many
command line options can effectively disable a NetBIOS network and prevent computers from rejoining it. According to Sir Dystic, "NBName can disable entire LANs and prevent machines from rejoining them...nodes on a NetBIOS network infected by the tool will think that their names already are being used by other machines. 'It should be impossible for everyone to figure out what is going on,' he added."
