| Device | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Known hardware tampering | None | [] | Risk of hardware tampering is very low for a mass-market consumer electronic device. |
| Known vulnerabilities | None | [] | No publicly disclosed specific vulnerabilities for this model. Its simple functionality presents a small attack surface. |
| Prior attacks | None | [] | No publicly reported attack instances targeting this specific model. |
| Updatability | Rare | [] | Firmware updates may be possible via a companion app, but frequency and long-term support are unclear. |
| Category score | 2 | ||
| System | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Authentication with other systems | Partial | [] | Uses standard Bluetooth pairing (e.g., PIN code) for connection. |
| Communications | Encrypted with up-to-date encryption | [] | Bluetooth connections are encrypted by default (e.g., using AES-CCM). Security depends on the Bluetooth version implemented. |
| Storage | No encryption | [] | The 4GB internal storage for music files is most likely not encrypted. |
| Category score | 2 | ||
| User Authentication | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Account management | Absent | [] | The earphones themselves have no user account system. A companion app may require an account. |
| Authentication | Basic | [] | Physical power on/off. Bluetooth pairing is the primary "authentication" method. |
| Brute-force protection | Absent | [] | The Bluetooth pairing process itself has no brute-force protection mechanism, but the need for physical proximity reduces this risk. |
| Event logging | Absent | [] | The device itself has no event logging capability. |
| Passwords | Default/Common/Easy to guess | [] | Bluetooth pairing typically uses common PINs like "0000" or "1234", or requires no PIN. |
