Brief purpose of API: Allow content to understand if current network connectivity is metered in order to allow apps to limit consumption
General Use Cases:
- Read current bandwidth estimate or ask if connection is metered
- Listen for connection change events
Inherent threats: Privacy (de-anonymize users based on connection change events?)
Threat severity: Low
Regular web content (unauthenticated)
Use cases for unauthenticated code: Read current bandwidth estimate or ask if connection is metered
Authorization model for normal content: Implicit
Authorization model for installed content: Implicit
Potential mitigations: Maybe fuzz the exact time of the network change event in a similar manner to idle API.
Trusted (authenticated by publisher)
Use cases for authenticated code: As above
Use cases for trusted code: As above
Potential mitigations: As above
Certified (vouched for by trusted 3rd party)
Use cases for certified code: As above
Authorization model: As above
Potential mitigations: As above
