1. Insecure Communication Protocols in Automated Milking Systems (AMS) Description:
Automated Milking Systems (AMS), also known as robotic milking machines, automate cow milking and health monitoring processes. These systems often use various communication protocols to transmit data between the control software, monitoring devices, and robotic milking units. Some of the popular vendors for AMS include: DeLaval, Lely, BouMatic, GEA, AMS-Galaxy and Afimilk. Common protocols in AMS setups include Modbus, MQTT, and proprietary, unencrypted protocols. These are primarily used to control operations and transmit cow health metrics, system diagnostics, and process commands. Unfortunately, many of these protocols lack encryption and authentication, exposing them to security risks.
Modbus: Modbus is a widely used protocol in ICS, SCADA, and OT environments, designed for reliability and speed, not security. Without user authorization, device authentication, or data encryption, Modbus devices are inherently vulnerable to attacks.
MQTT: MQTT is a widely used protocol in IoT and IIoT, facilitating one-to-many communication through brokers using a publish-subscribe model (PSM). Clients publish or subscribe to topics that organize message delivery to subscribers.
Security Impact:
Plaintext Communication: Protocols like Modbus and unsecured MQTT transmit data without encryption. This plaintext communication makes it easy for attackers to intercept, view, and potentially manipulate sensitive information. In the case of AMS, intercepted data could include system commands, animal health metrics, or maintenance schedules, all of which can be leveraged to disrupt farm operations.
Lack of Authentication: Many AMS communication protocols do not enforce authentication. Without a verification mechanism, unauthorized entities can inject commands or tamper with communication streams. This vulnerability can lead to operational manipulation, with attackers potentially altering milking schedules or settings, risking both animal welfare and production consistency.
Proprietary Protocols: AMS manufacturers often use proprietary protocols with minimal or inconsistent security implementations. Such protocols are generally closed source and lack standard security features, making it difficult to ensure they’re protected against modern threats.
Replay Attacks: Modbus communications may lack mechanisms to prevent replay attacks. Attackers can capture and replay legitimate network traffic to perform unauthorized actions, impersonate valid users, or disrupt system operations.
Risk factors:
Ease of Exploit: High, due to the widespread use of unencrypted protocols and lack of authentication.
Prevalence: Common in AMS, as these systems prioritize operational functionality over security.
Detectability: Moderate; attacks often require dedicated monitoring systems to detect abnormal commands or communication patterns.
Impact: High, with potential disruptions to milking routines, animal health, and production efficiency.
Known Cases:
Swiss Dairy Farm Incident: In 2024, a ransomware attack targeted a Swiss dairy farmer’s robotic milking system. The attackers encrypted the data, demanding a ransom of
$10,000. This attack disrupted the farmer’s ability to access critical data on milk production and cow health, leading to the death of a pregnant cow and her unborn calf
General Vulnerabilities in AMS: Studies have shown that industrial IoT devices, including AMS, are vulnerable to various cyber threats. These vulnerabilities can be exploited for command injection,
How to Prevent:
Firmware and Software Updates: Regularly update AMS firmware to ensure the latest security improvements and patch any known vulnerabilities in proprietary protocols.
Network Segmentation: Isolate AMS systems on a separate, secure network. Network segmentation limits access to the AMS and reduces potential exposure to threats.
Implement Strong Authentication and Authorization: Ensure that any communication between AMS components requires robust authentication. For instance, using certificates or tokens can help ensure only authorized systems can communicate with the AMS.
Monitoring and Alerting: Establish continuous monitoring for unusual commands or traffic patterns in AMS systems. Intrusion detection systems (IDS) or dedicated AMS monitoring solutions can help detect and respond to suspicious activity.
VPN for Remote Access: If remote management is necessary, secure it using a VPN. This adds a protective layer to prevent unauthorized external access and data interception.
By upgrading AMS to secure communication standards, dairy farms can prevent unauthorized access to their robotic milking systems, ensuring that operations are safe, reliable, and productive while protecting both animal welfare and farm productivity.
