- Platform: Android
- Weakness: MASWE-0038
- Weakness in the numbering of the MASWE beta: MASWE-0055
- Profiles: L2 (advanced security)
- Type: dynamic, filesystem, manual
- Prerequisites: identify-sensitive-screens
- Knowledge: MASTG-KNOW-0053
- Best practices: MASTG-BEST-0014
Overview
This test verifies that the app hides sensitive content from the screen when it moves to the background. This is important because Android captures a task screenshot of the app UI when it moves to the background. This screenshot is used for the Recents screen and transitions, and can expose sensitive content if the app does not protect it.
Steps
- Exercise your app until you get to each of the screens identified as sensitive. While on each of those screens, move the app to the background (for example by pressing Home or opening the Recents screen and exiting it) and continue to the next screen.
- Use MASTG-TECH-0002 to copy the screenshots taken by the system to your laptop for further analysis. The system stores the screenshots in their containers
/data/system_ce/0/snapshotsor/data/system.
Observation
The output should include a collection of screenshots cached when the app entered the background state.
Evaluation
The test case fails if any screenshot displays sensitive data that should have been protected.
Further Validation Required:
Inspect each screenshot visually, looking for sensitive information such as passwords, tokens, personally identifiable information, or other sensitive content that should not be exposed when the app is in the background.
