The RF communication protocol in the Micca KE700 car alarm system does not encrypt its data frames. An attacker with a radio interception tool (e.g., SDR) can capture the random number and counters transmitted in cleartext, which is sensitive information required for authentication.
Description: CAPEC-37: Retrieve Embedded Sensitive Data
Solutions
* Implement encryption: The entire transmission frame must be encrypted using a standard, proven symmetric algorithm (e.g., AES-128).
* Authenticate the frame: The encrypted payload should include a Message Authentication Code (MAC) to prevent tampering or spoofing.
