2) EMail Forging :-
Email forging allows an attacker to disguise
the source of an email and send it to the victim. Most attackers use this
technique to fool the victim into believing that somebody else has send
the particular email.
The SMTP protocol makes it extremely easy for an attacker to send forged
emails to a remote user.
Typically an attacker carries out email forging by following steps:
1) Start Command Prompt and type the following command- c:/>telnet smtp.mailserver.com 25 or c:/>telnet mail.domain.com 25 example:- c:/>telnet smtp.gmail.com 25
The above command opens a telnet connection to the specified remote mail
server on port-25. Where port-25 is the default SMTP port on which outgoing
mail daemon runs.
2) Once you are connected to the mail daemon of remote
mail server, you would be greeted with a message similar to following:-
If you are not familiar with the smtp mail daemon commands
then enter the keyword 'help' at daemon which may reveal all the supporting
commands as shown below.
correct sequence of commands to be executed is:-
a) helo mailserver1.com
b) mail from:firstname.lastname@example.org
c) rcpt to:email@example.com
e) .(dot command represents end of mail body)
This all as shown in figure below:
EMail forging by this technique
does not possible, if mail relying is disabled by it's service provider.
