Potential Failure Points
The upcoming UI introduces automated behaviors that can break user expectations and open attack vectors.
- Automatic favoriting of passes could expose sensitive transaction data without user consent.
- Limited visibility of the unstar option may cause users to retain unwanted passes, increasing the attack surface.
- Floating action button misuse could be hijacked by malicious overlays to capture tap events.
Privacy Traps
Design choices place personal information in plain view and potentially share it with external services.
- Pass metadata displayed on the home screen reveals travel, loyalty, and payment details to shoulder surfers.
- Data synchronization across devices may transmit favorite‑pass identifiers unencrypted.
- Third‑party analytics could log which passes are auto‑favorited, enabling user profiling.
Recommendations
Mitigate the identified risks with stricter controls and transparency.
- Implement explicit opt‑in for auto‑favoriting.
- Provide clear, accessible controls to unstar passes.
- Encrypt all pass metadata in transit and at rest.
- Audit third‑party SDKs for unauthorized data collection.
