Security Evaluation

1. Device Security

Criterion Value Proof Comment
Known hardware tampering Rare 🔗 Proof Simple relay-based design; physical access only allows manual control, no credential extraction from hardware.
Known vulnerabilities Rare 🔗 Proof Minor cloud API vulnerabilities reported in 2021 have been patched; no critical on-device vulnerabilities remain.
Prior attacks None 🔗 Proof No widely documented real-world exploitation incidents targeting this specific model.
Updatability Very common 🔗 Proof Regular OTA firmware updates for stability and security, including HomeKit compatibility patches.
Category Score Score: 2 / 3

2. System Security

Criterion Value Proof Comment
Authentication with other systems Full 🔗 Proof Works with Apple HomeKit, Amazon Alexa, Google Assistant and SmartThings with standard authentication protocols.
Communications Encrypted with up-to-date encryption 🔗 Proof Cloud control uses TLS 1.2 encryption; HomeKit communication uses Apple-standard end-to-end encryption.
Storage No encryption 🔗 Proof Only Wi-Fi credentials and basic config stored locally; no large sensitive data set on device.
Category Score Score: 2 / 3

3. User Authentication

Criterion Value Proof Comment
Account management Basic 🔗 Proof Standard account with device sharing; HomeKit adds separate user permission management.
Authentication Basic 🔗 Proof Password-based Meross account login; two-factor authentication is not natively supported.
Brute-force protection Basic 🔗 Proof Cloud platform implements basic login attempt rate limiting and temporary lockout.
Event logging Partial logging 🔗 Proof Door open/close events are logged; detailed account access audit trail is not available.
Passwords Require change after setup 🔗 Proof No default device credentials; user account password created during registration.
Category Score Score: 2 / 3
