  1. Staying Safe in Cyberspace

  2. What do YOU do online? • Send and receive e-mail • Shop • Research • Instant messaging/chat • Social networking/blogging

  3. What are the dangers? • Malicious attachments • Malicious websites • Phishing/fraudulent e-mails • Merchants with weak security • Search results (yes, really!)

  4. Now what? • Does all this bad stuff mean you should give up on the web? NO WAY!

  5. Get online! • Stay connected with family • Communicate with friends • Keep up on current events • Plan vacations • What else?

  6. E-mail security:Phishing • Phishing/vishing messages • Use scare tactics/threats • May “borrow” graphics to look more real • May use poor English • Ask for info the business already has • May be multi-pronged

  7. E-mail security:419 Scams • “I am a descendant of royalty…” • Most common is “fund transfer” scam • Request bank account numbers • May also request fees to cover transaction • Never, EVER respond!

  8. E-mail security:Malicious attachments • Bad guys use e-mail to spread malware • Beware of unsolicited attachments • Use an e-mail provider that scans attachments • Keep your antivirus software up to date

  9. E-mail security:Malicious links • Bad guys know we’re getting wise to attachments–they entice you to click links instead • Adult content • Breaking news • Shocking video

  10. E-mail security:Malicious links

  11. Instant messaging • Do you use chat? • Only accept chat requests from people you know • Don’t click unsolicited links • Don’t accept unsolicited file transfers

  12. Social Networking and Blogging • Facebook, MySpace, LinkedIn, etc… • Understand and use privacy settings • Only “friend” people you know • Information posted here makes you a more public person!

  13. What can I do? • Want to know a secret? • You don’t need to be a geek to stay safe online!

  14. What can I do? • Be skeptical and ask questions! • Did I really win a foreign lottery? • Does my bank need to be reminded of my account number? • Will the software in that ad really make my computer faster if I click “OK?”

  15. My favorite things…(Just like Oprah, but without the flattering lighting!) • Surf Safer—use Firefox! • Consider moving away from Internet Explorer

  16. Surf Safer • Use a phishing filter! • McAfee SiteAdvisor (free) • Rates search results • Prevents you from visiting known-bad websites

  17. Shop Safer • When using a credit card online, always look for: • https:// • Closed padlock • Your CC# is encrypted in transit

  18. E-mail Safer • Choose a good e-mail provider! • Is your e-mail scanned for viruses? • Will it attempt to alert you about phishing? • Ask around—what e-mail providers do trusted friends use? • Are they generally happy? • Do they get a lot of spam?

  19. E-mail safer • No e-mail provider is perfect! • Unfortunately, they all get spam

  20. E-mail safer • Cast a wary eye upon e-mail messages • Don’t be afraid to call your bank, ISP, or other businesses about phishing messages

  21. Handling phishing messages • Don’t: • Call any provided number • Reply to them via e-mail • Click any links or fill out any forms

  22. Handling phishing messages • Do… • Call your bank on a known-good number • Known-good: from the back of your card or bank statement • Report the message to your e-mail provider • Report the message to the FTC • Forward to uce@ftc.gov

  23. Other types of fraud… • Many types of fraud started offline but found new life on the Internet • Phone scams • Check scams • Text message scams

  24. Phone scams—”vishing” • Register with the National Do Not Call registry • https://www.donotcall.gov/ • Scammers will not honor this list! • Remain on guard, report scam calls to the FTC: 1-888-FTC-HELP

  25. Check scams • Arrive in “snail mail,” and may include: • Foreign business offers • Rental schemes • Overpayments • Sudden riches • Get more info on check scams at http://www.fakechecks.org

  26. Text message scams • Do you have a mobile phone? • Do you use it for text messaging? • Even if you don’t, scammers can still send messages to your phone • Disable text service if you don’t use it • NEVER respond to an unsolicited text message

  27. In conclusion… • It’s not possible or necessary to know about every threat • Remain skeptical • Continue learning • Ask questions!
