Email Spam and Phishing

Last modified on 04/03/2020

How to deal with email spam or Phishing attempts to acquire information such as usernames, passwords, and credit card details...

This article is intended to to help you become more aware of potential phishing emails.

From Wikipedia,

Email spam, also known as junk email or unsolicited bulk email (UBE), is a subset of electronic spam involving nearly identical messages sent to numerous recipients by email. Clicking on links in spam email may send users to phishing web sites or sites that are hosting malware.

Phishing is the act of attempting to acquire information such as usernames, passwords, and credit card details...

 

What should you do?

If you receive a suspicious email and know it is spam, follow these instructions to identify it as spam. Otherwise, check this article to see if it has been added to the examples. If it has not been added, please forward it to abuse@ttsd.k12.or.us.

Do not click on any links in a suspicious email. This includes unsubscribe links. If you do, do not fill out any forms that ask for your personal information. See the examples below.

If you ever have a question, don't hesitate to ask the Technology Department through a tech request, a call to the help desk (x4051) or by forwarding the suspicious email to abuse@ttsd.k12.or.us.

 

What happens if I fail to recognize a Phishing email?

If you fail to recognize a message as fake (see the examples below), then you may decide to reply to the message or follow the given directions. Phishing emails try to get personal information from you. One thing in particular is your email account and password. When you give them this information, a common use is to login to that account and send spam from it.

When spam is sent from your account, it is not just one or two messages. It is usually thousands of messages. This clogs our mail servers and slows delivery and receipt of potentially important and/or time sensitive messages. It can also cause major email providers, such as Comcast, Yahoo and Hotmail, to temporarily stop receiving email from us. Some companies will take a few days before they decide to accept mail from us again. Of course, this also applies to others we email regularly, like the City of Tigard.

A quick way to determine if the message is fake is if they want any account information that includes a password. The messages below are good examples.

Example Emails

The examples below are emails we have received in our district. A screenshot of the website that the link in the email will take you to is included. Notice that the sites in these examples do not look like our district website. Some of these emails were successfully used to get the username and password from members of our staff. When that happens, the spammer uses that login information to access the staff member's mailbox and sends more spam.

Thank you for using the eFax service

NOTE: This email is not specifically phishing. It may, in fact, be a virus or malware of some sort. I don't know, but I want you to learn the trick they used.

The Trick

An HTML link is simply some text that you click on which takes you to a web page. The web page is associated with a URL. Often you see something like the words "Click Here", but the text can be anything, even the URL itself.

In this case the text is the URL, i.e. http://... However, they spammer was tricky. I've highlighted the tricky part. It looks like an eFax link, but when you click on it, it does not go to eFax. Just to make the point, if you click on it, you will go to our district website. Try it.

However, the spammer chose something different. A good way to check is to put your mouse over the link and see what pops up. It should show you the URL that you expect, in this case, eFax. I have set that to show the evil URL that the spammer added. Try it.
