  2. Company: Deutsche Telekom Academic advisor: Yuval Elovici Technical advisor : Assaf Shabtai Project Team: Limor Segev Eran Frieman Carmel Karni Roles & Responsibilities

  3. Introduction • An Android OS could be attacked by hackers: • Open platform • Users will access the Internet intensively • Everyone can develop applications for Android • Successful attack on Androids may: • Expose private information • Prevent T-Mobile customers from using T-Mobile services • Flood T-Mobile’s customer service infrastructure and personnel. • No easy way exists to “fix” mobile devices.

  4. Introduction • The Current situation is that backup is possible for: • Documents • Media files • Not for Application files • Deutsche Telekom is interested in developing a platform that • will enable: • Backup and Restore users’ Android terminals • Remote monitoring and offline analysis of Android application

  5. System Requirements • The System has three major Components: Device Service, Server, MySql Database, Desktop application. • The System has two groups of users: Device holders, Managers. • Managers actions: • Produce reports / statistics • Add managers • Device holders actions: • Backup installed applications • Restore the device / specific application(s)

  6. System Requirements • The Device Service is configurable: • Enables auto or manual backup (on apk installation) • Enable / Disable the service • Restore applications on demand • The service keeps the login data (no need to re-insert when sending/receiving data from the server). • The service-agent will contact the server and get updates (for example about malwares detection) • The Server will be available for requests from both users types at all times. • Communication with the server will be done using HTTP.

  7. System Architecture 1. Downloading and installing a new application 2. System’s agent send the new application files (apk) to the external server 3. Sending the new application files (apk) to the storage server with additional information to enable restoring users’ systems 4. Backed-up application apk apk apk apk apk apk apk Internet Customer’s Android device Server Storage 5. Threat detection system checks files and alerts the server about threats

  8. System Architecture 3. Sending an alert to the user apk apk apk apk apk Storage Internet Customer’s Android device Server 2. Sending analysis result: “malicious application” • Threat detection system checks apks with status “UNCHECKED”
