2. Outline1) Introduction to Mobile Forensic!2) Forensic Analysis of iphone!- JailBroken!- iTune Backup les! 3. Forensic Soundness What did it mean for disk forensics?! Does it mean the same thing?! Mobile devices are volatile, by nature! Real time clock changing in memory all the time! Acquiring SMS messages may change their status to Read! Some tools run code on the device itself!! Our goal is to change as little as possible! Perhaps disable automatic sync when using Blackberry DesktopManager, and disable conversion to local time in ABC AmberConverter! 4. Evidence Take-In and Chain of Custody Document the scene! Handle with care, and gloves!! For the Chain of Custody form, nd the serial number! Dont forget MicroSD cards!! Photograph the device where it is found! Document what is showing on the screen, if anything! Power concerns! Take cables and documentation! 5. Blocking Network Connectivity Disable the radio! How can you be sure its disabled?! Faraday isolation! Not all products are created equal!!! Usually causes the battery to be depleted more quickly! Use a safe SIM card! Remember, you want to turn off the phones connectivity to theservice provider, as well as Wi and Bluetooth connectivity! Exercise: Disable network connectivity on your own phone.! 6. ! What! Phone call database! E-mail and memos! SMS/MMS! Internet and LAN access! Visited URLs and saved pages! Where! Location information! 7. ! Who! Owner details and user accounts! Contacts and cohorts!

Browser cache! 10. Location Tracking Location-based applications! Loopt! Google Latitude! Yahoo! Fire Eagle! Citysense! LifeBlog! Facebook (Friends on Fire)! Foursqare! Twitter! 11. GPS Embedded in Photos GPS coordinates embedded in Exif! Same Exif we talked about for disk forensics! This is often automatically added if the phone is GPS aware.! 12. Think Outside the Device Past usage information! Network service provider records! Look for paper bills! Detailed history of usage! Date and duration of calls! Numbers called! SMS message sent (no content retained)! NSP maintains detailed records! Calling IMSI and IMEI! Called IMSI and IMEI! Location: rst and last cell! Charging details! 13.
