  1. Smartphone Security How safe are you?

  2. Main Points • Malware/Spyware • Other Mischief • How a phone might get infected • Staying Safe • Malware • Loss • WiFi/Bluetooth

  3. I. Malware/Spyware on My Phone - What Can Go Wrong? QUERY1: If a hacker got into your phone, what would you NOT want him/her to see &/or copy…?

  4. Hackers can see and in some cases even alter: • calendars, address books, contact lists • photos • iTunes music files • text messages, old and new (even deleted ones) • details about every phone call • the location of the phone at all times • Web browsing details and history • Plus, all your subsequent phone calls could be recorded and forwarded to a third party

  5. Malware/Spyware on My Phone - What Can Go Wrong? Hackers can make calls from your phone without your knowledge QUERY 2: What websites or numbers would you NOT want a hacker to call from your phone…?

  6. Porn sites … $$$ • Overseas numbers … $$$ • The hacker herself. This turns the phone into a bugging device because he/she can hear everything you say and (maybe) do • Your contacts in the middle of the night

  7. Malware/Spyware on My Phone - What Can Go Wrong? QUERY 3: Is it safe to conduct financial transactions over my cell phone…?

  8. In January, 2010, a single developer created fake 99-cent Android apps for over 50 banks. The app prompted users for their banking username and passwords [Notes] • In 2011 a hacker built a botnet that could steal data such as online banking credentials off “jailbroken” iPhones [Notes]

  9. 2. Other Mischief • Have you ever heard of a DDOS (distributed denial of service) attack? What is it? • Can cell phones be directed by a “slavemaster” to slam their carrier with so much traffic it can’t handle it? • Yes, they can

  10. 3. How Does a Phone Get Infected? • Does a hacker need physical access to your phone? • NO • So how does the malicious code get there…?

  11. Malicious software can be: • downloaded by a click on a website link • opened in an email/text attachment • introduced by an infected app • introduced simply by clicking on Quick Response codes (those black-and-white squares starting to show up in ads)

  12. Via Bluetooth?! • Simply leaving your Bluetooth enabled while in a public place allows an intruder access • Hacker simply downloads software onto a laptop (available free on the web)and adds a Bluetooth antenna • Next slide gives examples of Bluetooth hacker activities

  13. “Bluesnarfing” - downloading any and all information from a hacked device (for example, address book information, photos, calendars, SIM card details) • Hacker could send a “corruption code” and completely shut down the phone and make it unusable • “Bluebugging” - hacker makes the compromised phone call another device (the one the hacker is using, or long-distance calls to worldwide locations) • The hacker could make “micro-purchases” with the hacked phone which show up on the subscriber’s bills http://tech.blorge.com/Structure:%20/2009/02/22/how-to-hack-bluetooth-cell-phones-and-how-to-protect-yourself/

  14. 4. Staying Safe • GOALS • 1. keep malware off your cell phone • 2. protect the information stored on your phone if it is lost • 3. protect from intrusion/theft during Wi-Fi or Bluetooth transmission • Each of these three will be discussed next…

  15. 4a. Keep Malware off Your Phone • Do not jailbreak your phone • Do not click on website links from unknown sources (1/3 of smartphone users have been negatively affected by a link they clicked) • Only download applications from trusted sources, such as reputable application markets (Remember to look at the developer name, reviews, and star ratings)

  16. Do not click on multimedia attachments in texts/emails from unknown sources • Always check the permissions an app requests • Using an official banking application is safer than banking through your mobile’s online browser

  17. Download a trusted mobile security anti-virus app for your phone • Learn how to update your operating system (http://www.tescotechsupport.com/2012/01/11/update-your-smartphone-software/). • Beware of Porn sites (Nearly one-quarter of malware on phones and tablets comes from visits to porn sites)

  18. How are we doing (malware)?

  19. Why might people click on website links or open multimedia attachments from unknown sources?

  20. 4b. To minimize damage if phone is lost or stolen • Password/passcode protect your phone • Log off mobile apps (Logging in every time prevents someone from having access if you lose your phone) • Backup and secure your data at least monthly (Contacts, documents, and photos, e.g.) • Install security apps that enable remote location and wiping • Wipe data on your old phone before you donate, resell or recycle it • Report a stolen smartphone

  21. How are we doing (if lost)?

  22. Why might people not password protect their phone?

  23. 4c. Wi-Fi/Bluetooth transmission • When transmitting information via wireless networks, use encryption • Disable Bluetooth when you are not using it

  24. How’re we doing (WiFi/Bluetooth)?

  25. Why might someone keep Bluetooth enabled when not using it?

  26. Last question – have you or anyone you know had any type of smartphone security breach?
