  • Start playing the spam song a few minutes before class starts
  • yada yada yada
  • What are you hoping to find out about or learn today?
  • spelling does not come from group Phish but from the fact that hackers often use ph for the letter F
  • note handouts: paypal.pdf and topemailtips.pdf
  • group debrief: In your groups, discuss the email problems that you have encountered with phishing. Has anyone ever clicked on any of the links in a fake email? If you did what happened? What sort of advice have you/would you give your patrons to help them avoid phishers? THEN move on to speed teaching minute (next slide)
  • Look for extensions like .pif, .exe, .com, .scr - common virus extensions in attachments Handouts: virusprotection_tips.pdf
  • note the fact that hotmail account address books CAN’T be exported! gmail okay but hard to get (invitation only) most free webmail accounts offer upgrades for $$$
  • note that ISPs generally have pretty generous email limits - much higher than 2MB. Explain POP mail vs webmail
  • On by default is good. On by default. Keep it on. By default, spam gets saved for a month in the Bulk folder. This allows you to make sure no good email gets stuck in there, and if it does you can tell Mail it’s not junk. You want to add new spam to the spam filter, and you want to add good email to your address book, so Mail won’t continue to think it’s spam. Image blocking - hmmm. Images are safe, but loading them will slow your email viewing down. So let SpamGuard make the choice for you. You can always view them later.
  • Plain text can be read by all email programs and loads much faster for dialup folks very useful in work-related emails or when sending to large numbers of people - discuss this in class so they understand the difference!
  • Please include a slide like this for each exercise with the numberof the exercise and exercise name. Feel free to add a graphic or sound appropriate to the exercise (humor is fine)
  • Handouts for this section: spywarepervasive.pdf
  • demo anti-spyware software here. show spybot and microsoft’s tool. mention spybot is on the cd.
  • activex settings are controlled in Internet Options in IE
  • Spybot on the class cds
  • show netscape and its advertising. also use yahoo mail as an example - adware is there, too
  • note adaware is on cd demo adaware show popup blocking in IE 6 note it’s not available in IE 6 without service pack 2 in windows xp
  • this is a small group exercise. they should trade off being staff and patron.

  • What Is Phishing?
    • Phishing (also known as carding and spoofing) is an attempt to fraudulently acquire sensitive information, such as passwords and credit card details, by masquerading as a trustworthy person or business in an apparently official electronic communication, such as an email or an instant message. The term phishing arises from the use of increasingly sophisticated lures to "fish" for users' financial information and passwords.

  • What Is a Computer Virus?
    • A virus is a self-replicating program that spreads by inserting copies of itself into other executable code or documents.
