Preventing problems

• Many malicious acts, such as identity theft,
  viruses, and scams, are perpetrated through
  e-mail. The best protection from these schemes
  is knowing what to look for.

4
Why e-mail?

• There are currently over 500 million e-mail
  users worldwide. Currently, there are 50 billion
  e-mails sent every day. This is a huge potential
  market for people trying to sell, steal, or
  simply harm others.

5
A huge amount of bad e-mail

• According to a Canadian study, 73 of all e-mail
  sent in 2004 was SPAM. America Online currently
  blocks over 3 billion SPAM e-mails per day. With
  this many e-mails floating around, everyone needs
  to be aware of what to look for in e-mail.

8
Viruses and worms

• Many types of computer viruses are spread
  through e-mail. However, there are some steps
  that users can take to help prevent becoming
  infected.

9
Attachment safety

• Never open e-mail attachments from someone you do
  not know. If you think the attachment may be
  legitimate, send an e-mail to the person who sent
  it, and confirm that they indeed did send it.
• Always make sure your antivirus software is up to
  date. Your antivirus software will combat many
  bad attachments that could lead to a virus
  infecting your system.

10
Opening e-mails

• If you think something seems wrong with an
  e-mail, delete it immediately
• If you get a window asking you to install
  something when you open an e-mail, click No or
  simply exit, and then delete the e-mail
• If an e-mail directs you to a Web site that asks
  you to install something, click No or exit, and
  then delete the e-mail

11
Phishing

• Phishing is a way of fraudulently acquiring
  sensitive information, such as credit card or
  bank account information by tricking users with
  official-looking messages

12
Types of phishing scams

• E-mailPhishing e-mails can appear to come from
  legitimate institutions such as your bank, eBay,
  Visa, etc., but they really come from a criminal
  trying to steal information
• Instant Messaging (IM)With IM phishing, you will
  get an IM from someone claiming to be support for
  your IM provider, asking you for account
  information

13
Phishers have a goal

• They want your personal information
• Bank account numbers
• Password
• E-mail address
• Credit card numbers

To steal your identity
14
How to not become a phishy

• Never send sensitive account information in an
  e-mail message
• Never go to a sensitive site through an e-mail
  link always type the site name in your browser
  (such as www.paypal.com)
• Never give any password out to anyone.
• If your bank requires verification, do it over
  the phone or in person.
• Do Not provide any information to any person who
  contacts you unsolicited, claiming to be customer
  support

15
The SPAM problem

• SPAM is unsolicited commercial e-mail. SPAM
  e-mails are sent en mass, to thousands of people
  in an attempt to get them to purchase a product
  ranging from night lights to prescription
  medications. SPAM messages account for over 36
  billion e-mail messages per day.

16
Ways to combat SPAM

• Never buy anything from a SPAM e-mail SPAM
  continues to exist because it works
• Take advantage of SPAM filtering in your e-mail
  client (such as Outlook Express, AOL and MSN)
• Do not use your e-mail address to sign up for
  things on the Internet without reading the
  companys privacy policy (make sure they wont
  sell your e-mail address to other companies).

17
Chain letters

• Chain letters cover any variety of topics,
  anything from spiders in the toilet to free gift
  certificates or even getting paid to forward the
  e-mail. They are all hoaxes, and should be
  avoided.

18
Break the chain

• The problem with chain letters is the sheer
  volume of mail they create. If one person
  forwards 1 message to 10 people, and each of them
  forwards it to 10 people, by the sixth generation
  you have over 1 million messages. If you figure
  in the cost of each of those people reading the
  chain letter, you end up with a huge cost. This
  does not include the cost associated with the
  mail servers storing and sending all those
  messages, or slowing down because of the extra
  load.
