1) Open up MS-DOS/Command Prompt, by going to Run and typing cmd.

2) You should see a black window box. type in "nslookup".

3) At the very end of the message, there will be a ">". Type in "set type=mx"

4) Now another ">" will come up. Type in the name of the mail domain
of your victim. (hotmail.com, gmail.com, yahoo.com, etc.)

5) you should come up with a list of nameservers, MX servers, and
internet addresses. What we are interested in are the MX preferences.
Take note of the one with the highest MX preference. Now, type "exit".

6)Once you quit, type in this format: telnet [mail server] 25, where
telnet is the command, the mail server is the one with the highest MX
preference, and 25 is the port number.

Ex) telnet gsmtp183.google.com 25, where gsmtp183.google.com is a mail server for gmail.com.

7) If all is well, you should get a 220, meaning a greeting on a
connection. To make sure you are connected, type in "ehlo" or "helo".
If you get a 250 on either one, you're set.

8) now, type in "mail from:" and the email you will send "from".

Ex) mail from:

9) You should get a 250. Type in rcpt to: and the victim's email.

Ex) rcpt to:

10) Once you get a 250, you should now start the data. Type in data, and press enter. You should get a 354

11) First off, you have to start with the headers. Type "To: [Victim's
email nickname] [victims email]", without quotes. Press enter. Type
"From: [your fake name] [your spoofed email address]", without the
quotes. Press enter. Type in "Reply- To: [your spoofed email address]"
without quotes. This is the most basic type.

12) To start writing your message, press enter twice to skip a line.
Type whatever message you want, and BECAREFUL NOT TO SCREW UP. Your
message will screw up if you backspace.

13) To show that your message has ended, press enter, type "." (without

Hack Bsnl Broadband Adsl Router through Cmd

it works only for computers which have BSNL ADSL Router.

1.open command prompt by typing cmd in Run and click Ok.
2.You should see a black box.type there "telnet<space>Ip address of the computer" without quotes and press enter
3.it will ask for login username and password now.
4.bsnl provides a default user name and password for it's every user.it is important thing to change it or it will be hacked like this...
5.For most of the routers the default user name-password will be admin-admin or admin-password.
6.Type one of the username password pair and login.
7.Now you will be able to see a "Main Menu" consisting of LAN ,WAN, DNS Server, passwords etc..
8.To open any of the sub menu,type the appropriate number of the sub menu and press enter key.
9.it is sure that you can access the Ethernet ADSL Router of anyone by using any of the above mentioned password pair if the owner of it forgot to change the default username-password.

By this unauthorized access you can change the username-password what ever you want.You can change the router settings,you can copy router details,you can unblock WiFi signal if it is a WiFi transmitter Modem. etc etc...

Don't use it for illegal purpose......

Now you may be looking at this going, "What the hell is Telnet?". If you are, don't worry, I'll explain everything. First of all, Telnet is software that allows you to connect to another Telnet Host.In windows systems Telnet is usually called Telnet32.exe or Telnet.exe. In newer versions of windows it is Telnet32.exe.
*** Note to Windows XP users: Don't go and get the old version of Telnet, because you have a DOS-Based one. I'll give commands along this guide so you can enjoy it too. You have to either run "Telnet" or "cmd" and then "Telnet".

Telnet is not illegal and is used by thousands of remote computers to interchange data, share connections, and do many other things that would be impossible without it.The default port for Telnet is port 23. When I say for instance, 'Connect to the sys' I am referring to connecting on the system's default port for Telnet. Sometimes you can't determine a port so you will have to port scan a sys to find the Telnet Ports.
Port 25 is the 'Sendmail Protocol' port. We will be dealing with this port as well.

Telnet Security
Because there are so many problems with Telnet today involving cyber crime and hacking, SysAdmins often restrict anonymous use of their sys's Telnet Proxies. This is cheap and can be bypassed easily.Most SysAdmins are amatures at what they do and make me laugh.They restrict the Telnet proxies on port 23 and think that we can't telnet to other ports such as 81 and 25 because we can't use the Telnet Proxy. Well they are wrong. We can easily do it and we will. Let me point out a system that has this and was not effective. I will star out the IP for privacy.

Welcome to Microsoft Telnet. Telnet32.exe.

Ok people is there a problem there? How many addys did I get? Am I supposed to have those? Do I care? No. I am just demonstrating how sh1tty Unix-System security is and how easy it is to use the Telnet Proxy to your advantage. Here, I wil list some commands for all of you running under DOS.

C - Close the Current Connection
D - Display the sys's operating paremeters
O - Connect to a host name (on default port 23) [port]
q - Quit (Exit Telnet).
Set- Set Options
Send - Send data/strings to server
