LockUp

Cellebrite UFED self-defense app
icon

LockUp is an Android application that will monitor the device for signs for attempts to image it using known forensic tools like the Cellebrite UFED. Here is a blog I wrote.

  • Proof-of-Concept. Not meant as an in-depth defense
  • Android API 28, Does not require root
  • Relies on RECEIVE_BOOT_COMPLETED to start a Service and AccessibilityService
  • Monitors USB events through ACTION_USB_DEVICE, package installations, and known exploit staging locations on the filesystem
  • Detects Logical Extractions, File System Extractions, and Physical Extractions leveraging ADB
  • Will automatically respond with a factory reset with DeviceAdminReceiver
  • Beginning steps to researching more robust anti-forensic techniques

Signature Detection:

  • Exploit staging directories and known filenames
  • Known file hashes
  • Application names and certificate metadata
