Security Evaluation

1. Device Security

Criterion Value Proof Comment
Known hardware tampering Very common 🔗 Proof ESP8266 is widely documented; firmware dump and custom flash are easy
Known vulnerabilities Very common 🔗 Proof Multiple vulnerabilities found in early eWeLink firmware versions
Prior attacks Rare 🔗 Proof Occasionally seen in botnet scanning, not a primary Mirai target
Updatability Rare 🔗 Proof Firmware updates are infrequent, older hardware gets dropped quickly
Category Score Score: 3 / 3

2. System Security

Criterion Value Proof Comment
Authentication with other systems Partial 🔗 Proof Depends fully on eWeLink cloud; local mode has weak authentication
Communications Encrypted with obselete encryption 🔗 Proof Local communication uses outdated encryption algorithms
Storage No encryption 🔗 Proof Device configuration stored without local encryption
Category Score Score: 3 / 3

3. User Authentication

Criterion Value Proof Comment
Account management Basic 🔗 Proof Simple shared access, no granular permission control
Authentication Basic 🔗 Proof Password login only, 2FA not supported for this model
Brute-force protection Basic 🔗 Proof Only simple lockout after repeated failed login attempts
Event logging Partial logging 🔗 Proof Switch state events logged; no remote access audit logs
Passwords Default/Common/Easy to guess 🔗 Proof Default pairing credentials are well known and easy to guess
Category Score Score: 3 / 3
