Title
Micca KE700 Brute-force vulnerability due to low entropy
Summary
The Micca KE700 system relies on a 6-bit portion of an identifier for authentication within rolling codes, providing only 64 possible combinations. This low entropy allows an attacker to perform a brute-force attack against one component of the rolling code. Successful exploitation simplify an attacker to predict the next valid rolling code, granting unauthorized access to the vehicle.

Title
Micca KE700 Acceptance of previously used rolling codes
Summary
The Micca KE700 system contains flawed resynchronization logic and is vulnerable to replay attacks. This attack requires sending two previously captured codes in a specific sequence. As a result, the system can be forced to accept previously used (stale) rolling codes and execute a command. Successful exploitation allows an attacker to clone the alarm key. This grants the attacker unauthorized access to the vehicle to unlock or lock the doors.

Title
Micca KE700 Cleartext transmission of key fob ID
Summary
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.
