Homework 3 : Manually send a spam email (Report due
July 16th midnight)
In this simple assignment, you will need to use telnet to manually send a spam (faked) email to Dr. Cliff Zou at email@example.com. From this experiment, you will understand why there are so many untrusted email around and how easy for attackers to send out spam or phishing email.
Please follow the in-class illustration to send this faked email. In order to make these assignment email not be treated as the other spam email, you must follow the following specifications:
1. The sender email (shown in the "From: ...." field when you read an email) must be "fake@", you can use any domain name in the sender email address except cs.ucf.edu, longwood.cs.ucf.edu, or eecs.ucf.edu, or knights.ucf.edu.
2. The email must have a subject line as "CNT3004: firstname lastname". Put your name in the subject line so that you can be credited!
3. Put in some words in the content. Must have at
least two lines.
4. Submit a brief report
to WebCourse. Make sure that your report contains the screenshot image of your
telnet interaction command sequence. This is important because
some of your spam email will be lost in the email system, so I
will grade mainly based on your report's screen shot
You can type in two "rcpt to:" to include your own email
address for verification. In this way, if you didn't receive
your spam email, your email may have failed.
It is possible that your own computer cannot do this because
of the strict security policy on eecs email server. If that is
the case, you can first log in (using ssh) our department Linux
machine eustis.eecs.ucf.edu in order to do the telnet commands
(like what I showed in class). The accounts have been created
for those who don't already have accounts. The usernames are
their NIDs and the default password is Pyymmdd (their birth
year, month and day). If existing users don't remember their
password, please email firstname.lastname@example.org
for a password reset.
