Spam – any message, regardless of its content, that is sent to multiple mailing lists, individuals or newsgroups. Also called bulk e-mail or junk e-mail.

Fraudulent E-Mail

Be suspicious of any e-mail that requests: Credit card information Complete home

address Banking information Username or

passwords Social security number


Fraudulent e-mails are “spoofing” or “phishing” messages. Scammers use these methods to “fish” for consumer’s financial or other identifying information. These messages will create the impression the user has an urgent need to update his/her personal information.

Tips to Protect Against “Phishing”

Remember that e-mail headers can be forged Avoid providing info or filling out forms via e-mail

because the data is not secure Avoid clicking links within an unsolicited e-mail

message Ensure a website is secure before providing any

personal information. Check for an address that begins with https or the browser has a lock icon in the address bar or bottom of the screen.


The Look of Fraudulent E-Mails


Hovering over a link with the mouse cursor will reveal the real address the

link will take you to.

Don’t be fooled by the official looking header in

this fraudulent e-mail.

General Safety Tips Use spam filters. Be suspicious of unsolicited e-mail. Treat e-mail attachments with caution. Don’t click links in e-mail messages. Create strong passwords. Use a combination of letters, numbers

and symbols. Change passwords frequently. Use a pseudonym when participating in public online forums, chat

rooms, discussion boards, etc. Don’t reveal username, passwords, or personal information to

anyone other than a trusted party. Install anti-virus software and keep it up to date. Install a personal firewall and keep it up to date. Install spyware/adware software and keep it up to date.

Don’t Be Afraid of the Internet

Use the Internet to your advantage. Don’t know what that Website is your child visits

daily? Don’t know that acronym or short hand in your
