| Criterion | Value | Proof(s) | Comment |
| Known hardware tampering | None | [2] | As a sealed, low-cost consumer device, there are no documented cases of widespread hardware tampering or built-in hardware security features like a secure enclave. |
| Known vulnerabilities | Rare | https://www.bleepingcomputer.com/news/security/new-bluetooth-flaw-lets-attackers-impersonate-devices/ |
Older models had documented Bluetooth vulnerabilities. While this model is newer, the potential for similar Bluetooth-level vulnerabilities exists, though none are widely reported for this specific model yet. |
| Prior attacks | None | [3] | There are no publicly documented widespread, targeted attacks specifically against the Xiaomi Smart Band 8. Most issues are theoretical or related to general platform vulnerabilities. |
| Updatability | Very common | [4] | Xiaomi frequently pushes firmware updates through the Mi Fitness companion app to fix bugs and add features. |

| Authentication with other systems | Partial | [5] | The band can be used to unlock the paired smartphone, but it doesn't serve as a full security key for authenticating with third-party systems. Its integration is limited to the Mi Fitness ecosystem. |
| Communications | Encrypted with up-to-date encryption | [6] | Communication between the band and the phone is via Bluetooth 5.1 LE, which supports encryption. Data synced to Xiaomi's cloud is also transmitted over encrypted channels (HTTPS). |
| Storage | No encryption | [7] | There is no evidence or documentation to suggest that the limited data stored temporarily on the band itself (before syncing) is encrypted. This is typical for fitness trackers in this price range. |

| User Authentication | |||
|---|---|---|---|
| Criterion | Value | Proof(s) | Comment |
| Account management | Full | [8] | All data and settings are tied to a Xiaomi Account, which allows for password changes, data management, and supports two-factor authentication for enhanced security. |
| Authentication | Absent | [9] | The device itself has no passcode or biometric authentication. Security relies entirely on the physical proximity to the paired and unlocked smartphone. |
| Brute-force protection | Absent | [10] | The device has no on-device password, so brute-force attacks are not applicable at the device level. Protection exists at the associated Xiaomi Account level, but not on the band itself. |
| Event logging | Partial logging | [11] | The Xiaomi Account system logs sign-in events from different devices, which can be viewed by the user. However, the band itself does not provide detailed security event logs. |
| Passwords | Default/Common/Easy to guess | [12] | This is interpreted as there being no password on the device at all. Anyone who picks up the device can swipe through its menus and see recent fitness data. |
