Security Evaluation
1. Device Security
| Criterion | Value | Proof | Comment |
|---|---|---|---|
| Known hardware tampering | Very common | 🔗 Proof | Tuya-based chipset; firmware dumping is publicly documented |
| Known vulnerabilities | Very common | 🔗 Proof | Many Tuya stack vulnerabilities apply to this bulb model |
| Prior attacks | Rare | 🔗 Proof | Rare direct botnet compromise, but Tuya cloud attack chains exist |
| Updatability | Rare | 🔗 Proof | Irregular firmware updates; short support lifecycle |
| Category Score | Score: 3 / 3 | ||
2. System Security
| Criterion | Value | Proof | Comment |
|---|---|---|---|
| Authentication with other systems | Partial | 🔗 Proof | Relies on Wyze cloud; local control authentication is weak |
| Communications | Encrypted with obselete encryption | 🔗 Proof | Older encryption protocols used for local device communication |
| Storage | No encryption | 🔗 Proof | Almost no persistent local storage on the bulb |
| Category Score | Score: 3 / 3 | ||
3. User Authentication
| Criterion | Value | Proof | Comment |
|---|---|---|---|
| Account management | Basic | 🔗 Proof | Basic shared access, cannot set fine-grained permissions |
| Authentication | Basic | 🔗 Proof | Password login, two-factor authentication optional |
| Brute-force protection | Basic | 🔗 Proof | Simple login lockout, no intelligent risk detection |
| Event logging | Partial logging | 🔗 Proof | On/off state events logged; no detailed access audit logs |
| Passwords | Require change after setup | 🔗 Proof | Password change required at first login, weak complexity requirements |
| Category Score | Score: 2 / 3 | ||
