HP this week shared the results of a security assessment revealing that virtually all smartwatches with network and communication functionality are vulnerable to cyberattacks.
The study, conducted by HP Fortify, found that 100 percent of the tested smartwatches contain significant vulnerabilities, including poor authentication, lack of encryption and privacy issues.
HP said that it evaluated 10 of the top smartwatches currently on the market, along with their Android and iOS apps, from an attacker's perspective.
To conduct the assessment, HP used its Fortify on Demand IoT testing methodology, which combined manual testing along with the use of automated tools. Devices and their components were assessed based on the OWASP Internet of Things Top 10 and the specific vulnerabilities associated with each top 10 category, HP said.
The results were not surprising to HP researchers, and it shouldn’t be surprising to any security professional.
The most common security issues reported by HP include:
• Insufficient User Authentication/Authorization: Every smartwatch tested was paired with a mobile interface that lacked two-factor authentication and the ability to lock out accounts after 3-5 failed password attempts. Three in ten, 30 percent, were vulnerable to account harvesting, meaning an attacker could gain access to the device and data via a combination of weak password policy, lack of account lockout, and user enumeration.
• Lack of transport encryption: Transport encryption is critical given that personal information is being moved to multiple locations in the cloud. While 100 percent of the test products implemented transport encryption using SSL/TLS, 40 percent of the cloud connections continue to be vulnerable to the POODLE attack, allow the use of weak cyphers, or still used SSL v2.
• Insecure Interfaces: Thirty percent of the tested smartwatches used cloud-based web interfaces, all of which exhibited account enumeration concerns. In a separate test, 30 percent also exhibited account enumeration concerns with their mobile applications. This vulnerability enables hackers to identify valid user accounts through feedback received from reset password mechanisms.
• Insecure Software/Firmware: A full 70 percent of the smartwatches were found to have concerns with protection of firmware updates, including transmitting firmware updates without encryption and without encrypting the update files. However, many updates were signed to help prevent the installation of contaminated firmware. While malicious updates cannot be installed, lack of encryption allows the files to be downloaded and analyzed.
• Privacy Concerns: All smartwatches collected some form of personal information, such as name, address, date of birth, weight, gender, heart rate and other health information. Given the account enumeration issues and use of weak passwords on some products, exposure of this personal information is a concern.
HP did not release the specific smartwatches or manufacturer for models tested, but did say they notified the smartwatch makers.
“HP’s practice is to notify the affected companies and provide them with an opportunity to address the security issues uncovered by our testing,” an HP spokesperson told SecurityWeek.
“Smartwatches have only just started to become a part of our lives, but they deliver a new level of functionality that could potentially open the door to new threats to sensitive information and activities,” said Jason Schmitt, general manager, HP Security, Fortify. “As the adoption of smartwatches accelerates, the platform will become vastly more attractive to those who would abuse that access, making it critical that we take precautions when transmitting personal data or connecting smartwatches into corporate networks.”
“HP’s SmartWatch Security Study found that that smartwatches showed a lack of transport encryption protocols. While every device implemented encryption using SSL/TLS, 40 percent of devices continued to be vulnerable to known vulnerabilities such as POODLE, or still used SSL v2,” Kevin Bocek, Vice President of Security Strategy for Venafi, told SecurityWeek.
"The Internet of Things (IoT) will continue to be a frequent target for cybercriminals as its prevalence in the market increases. Security, however, appears to be an afterthought when it comes to Internet enabled devices such as Smartwatches,” Bocek said.
HP recommended that smartwatch users hold off on using sensitive access control functions such as car or home access unless strong authorization is offered. Additionally, HP said enabling passcode functionality, ensuring strong passwords and instituting two-factor authentication will help prevent unauthorized access to data.
