Over the past month, our team has analyzed the applications Expedia and Google Trips. These apps help users plan trips to locations abroad with features to order reservations and plan day trips. Our goal for analyzing these applications was to find out how much information they hold for forensic investigators. This will in turn give investigators an easier time catching suspects.Findings
The application Expedia has very little, if any, information on the system itself. It appears to only store information if the user purchases a ticket. The only other thing we found was sometimes there may be a flight plan stored on the system, but that’s it.
Google Trips, on the other hand, stores most if not all of the information on the system itself. Specifically, it contains all reservations, day trips, and other user input on the system. The application also stores all locations and events of the city that the user is visiting. If a person uses this application rigorously it would provide investigators with a lot of information. The application relies on MIDs, or a set of identifiers provided by Google. When correlated with the locations using certain items in the database, one can easily find the location of the corresponding MID.Conclusion
The team’s next project will involve game app forensics. What information do apps downloaded from the playstore keep? What is stored internally? The team’s goal is to find as much information as we can about internally stored device data from two game apps. The apps are unknown as of now.
