Kaspersky Lab experts investigating the experimental cloud infrastructure for advanced bionic prostheses have identified several previously unknown security issues that could enable a third party to access, manipulate, steal or even delete the private data and more of device users.
The findings were shared with the manufacturer Motorica, a Russian high-technology start-up that develops bionic upper limb prostheses to assist people with disabilities, enabling them to address the security issues.
The Internet of Things (IoT) is no longer just about connected smartwatches or smart homes, but also about advanced, complex, increasingly automated ecosystems. These include connected healthcare cyber technologies. In the future, such technologies could shift away from being purely support devices to becoming mainstream and used by consumers keen to extend the capabilities of the ordinary human body through a process of cybernetization. It is therefore important that any security risks that could potentially be exploited by attackers are minimized by investigating and addressing security issues in current products and their supporting infrastructure.
Kaspersky Lab ICS CERT researchers, in partnership with Motorica, have undertaken a cybersecurity assessment of a test software solution for a digital prosthetic hand developed by the Russian start-up. The solution itself is a remote cloud system, an interface for monitoring the status of all registered biomechanical devices. It also gives other developers an existing toolset for analysis of the technical condition of devices like smart wheelchairs, artificial hands, and feet.
The initial research identified several security issues. These include insecure http connection, incorrect account operations, and insufficient input validation. When in use, the prosthetic hand transmits data to the cloud system. Due to the security gaps, an attacker could:
- Gain access to information held in the cloud about all the connected accounts (including logins and passwords in plaintext for all the prosthetic devices and their administrators)
- Manipulate, add or delete such information
- Add or delete their own regular and privileged users (with administrator rights)
“Motorica is a high-technology, trusted and socially responsible company focused on addressing the challenges faced by people with physical impairment,” said Vladimir Dashchenko, Security Researcher at Kaspersky Lab ICS CERT. “As the company prepares for growth, we wanted to help it ensure the right security measures were in place. The results of our analysis are a good reminder that security needs to be built into new technologies from the very start. We hope that other developers of advanced connected devices will want to collaborate with the security industry to understand and address device and system security issues and treat the security of devices as an integral and essential part of development.”
“New technologies are bringing us to a new world in terms of bionic assisting devices,” said Ilya Chekh, CEO at Motorica. “It is now of crucial importance for the developers of such technologies to collaborate with cybersecurity solution vendors. That will allow us to make even theoretical cases of attacks on the human body impossible,”
To keep the devices safe, Kaspersky advises that companies:
- Check out threat models and vulnerability classifications for the relevant web-based and IoT technologies, provided by industry experts, such as OWASP IoT Project.
- Introduce secure software development practices based on proper lifecycle. To evaluate existing software security practices use a systematic approach — for example, OWASP OpenSAMM.
- Establish a procedure for obtaining information on relevant threats and vulnerabilities to ensure proper and timely response to any incidents.
- Regularly update operating systems, application and device software and security solutions.
- Implement cybersecurity solutions designed to analyze network traffic, detect and prevent network attacks – at the boundary of the enterprise network and at the boundary of the OT network.
- Use a protection solution with machine learning anomaly detection (MLAD) technology to reveal deviations in IoT devices’ behavior — for early detection of attack, failure or damage of the device.
