  1. How to stay safe online! Advice and tips for using social media safely

  2. It’s magic! • https://www.youtube.com/watch?v=F7pYHN9iC9I • It’s not really magic, it’s all online

  4. Concerns • Identity Theft • Physical Theft/Burglaries • Sexual Predators and Stalkers • Spam and Malware • Reputation and Employment

  5. Reasons • Privacy settings • Over Sharing • Location based data/GPS tagging

  6. Identity Theft

  7. Privacy Settings • “Free” services online, make their money by selling you to third parties • Because of this, privacy settings by default are almost completely open • You should limit your profile to only be able to be viewed by friends • Facebook has ~170+ privacy settings, scattered throughout several pages

  8. Apps • Anytime that you install an app, it asks you to allow it a multitude of different permissions • Even if you lock your profile down, you can still be making everything freely available to apps • A great example of this is at http://www.takethislollipop.com

  9. Friend Requests • The idea of a social network is to gather friends, just make sure that you only accept requests from people you actually know • Accepting unknown people as friends is giving your information away just like granting apps permission • Once they have your information they can target you in spear-phishing emails and other forms of spam

  10. Passwords and User Names • We constantly preach about not using the same password on multiple sites, but using the same user name can be just as bad • Programs like LastPass and Keepass can store your information for you in a central location • Remember the HB Gary Federal hack last year? • The CEO used the same user name and password across multiple systems

  11. Don’t make it easy • It sounds silly, but don’t take a picture of your credit card and post it online • https://twitter.com/needadebitcard • Was created to “shame” people who did just that • Remember, if it sounds too good to be true, it most likely is

  12. What are some good ways to effectively manage privacy settings?

  13. How can I process all of this? • There are apps out there that can help! • You do, however, need to be careful about what apps you choose, so you don’t fall in to what we’ve already talked about • Either verify that the author/creator of the app is a trustworthy source, or just do a Google search for reviews • If you can’t find anything easily, it’s likely not a good program

  14. Privacyfix.com • Privacy Fix installs as an app in your web browser (Firefox and Chrome), it then scans your privacy settings in Facebook and also in your Google account if your logged in to them • It provides you easy ways to “fix” open privacy settings, but does it in a way to teach you • http://privacyfix.com

  15. ShareSafe • Is an app in Facebook, created by F-Secure • Scans links in your private messages, and on your wall • Allows you to scan links for safety before you post them on your wall

  16. Physical Theft/Burglaries Don’t invite them in

  17. Can anyone give an example of why tagging photos with GPS location data is a bad idea?

  18. Going away on vacation? • Don’t post dates of when you are leaving and coming back from vacation. • Wait until after you get back to post pictures • Turn GPS tagging off on your pictures so people can’t find out as easily where you live • http://weknowyourhouse.com/ • https://twitter.com/WeKnowYourHouse • Don’t post things about your house that might make it vulnerable • This could never happen to me! Right?

  20. Predators and Stalkers

  21. Imagination isn’t always good • Anyone can pretend to be anything online • Don’t accept friend requests from people you don’t know • Turn off GPS tagging on your posts/photo upload • If someone is following you, you could be telling them exactly where you are!

  22. Malware and Spam Be careful what you click

  23. The target has shifted • Malware is being created with the end user as the vulnerability instead of flaw in software • Don’t click on links sent from people you don’t know • Be wary of links that are even sent from “friends” their accounts could have been compromised • A common tactic is to send a link with a caption that the video is related to something currently going on in the world or related to you (e.g. “Footage of Bid Laden Kill” or “you even see him taping you, that’s awful”

  24. Do you have your phone number on facebook? • Does your number fall between (000)000-0000 and (999)999-9999? • A vulnerability was found in Facebook, just last week, that allowed anyone to search for a number and connect it to a name • Facebook fixed this vulnerability, however their “fix” was to limit the amount of searches that an IP address could do in a specified amount of time • If your telemarketer phone calls start to pick up, you might know the reason why now

  25. Malware through the phone • Another trend recently is to receive a phone and be greeted with “I am calling you from Windows!” • They try to convince you that your computer has errors and viruses and you need to download their software and pay them money to fix it • The software is a backdoor giving them direct access to all of your files, and some people have paid upwards of $500 for their “fix”

  26. I authorized what? • Certain apps will ask you for permission to do all sorts of stuff, even send messages on your behalf • While possibly unintentional, they can still have the effect of spamming your friends • A Happy Birthday app is a more common one of this, that automatically sends all of your friends a private message with birthday wishes

  27. I know… • There are several websites that show what malicious websites are capable of extracting from your web browser • …what websites you’ve visited • …who is on your Gmail contact list • …what Firefox addons are installed • …what you’ve previously watched on Youtube • …what sites you are logged in to • They can steal a browsers auto-complete data • They can even activate a computers camera and microphone • This is a great write up on all of the facets: • http://blog.whitehatsec.com/introducing-the-i-know-series/

  28. Your Online Reputation Your current and future jobs might depend on it

  29. What are some good examples of oversharing?

  30. Am I oversharing? • This is a short list of things you should not share: • Full Name (especially your middle name) • Your birth date • Hometown • Phone numbers • Relationship status • Your school name/location/graduation dates • Pet names • These are answers to some of the most commonly asked “forgot password” questions, and with this information anyone could reset your password

  31. Have you ever Googled yourself? • You might be surprised what you find • Facebook has a privacy setting, that by default makes your profile searchable • This is one of the settings PrivacyFix helps you find

  32. Do you hate your boss? • Don’t post it on Facebook! • Would you want to post that your hungover, taking drugs, or what your brand new phone number is? • Sadly, these people all do • http://weknowwhatyouredoing.com/
