Organizations around the world are observing this Shadow IoT phenomenon, where employees are bringing unauthorized devices into the enterprise. With this onslaught of unknown and unauthorized devices, IT and security teams often won’t know these devices are on the corporate network nor how they impact an organization’s overall security posture.
Unauthorized IoT Devices on the Rise: The top unauthorized IoT devices Zscaler observed include digital home assistants, TV set-top boxes, IP cameras, smart home devices, smart TVs, smart watches, and even automotive multimedia systems.
Manufacturing & Retail Industries Top IoT Traffic Volume: Manufacturing and retail customers generated the highest IoT traffic volume (56.8%) followed by enterprises (23.7%), entertainment and home automation (15.7%), and healthcare (3.8%).
Majority of IoT Transactions are Insecure: 83 percent of IoT-based transactions are occurring over plain-text channels, whereas only 17 percent are using secure (SSL) channels.
Exponential Increase of IoT Malware: Zscaler blocked 14,000 IoT-based malware attempts per month. That number has increased more than seven times than the May 2019 research.
New Exploits Emerging to Target Unauthorized Devices: New exploits that target IoT devices are popping up all the time, such as the RIFT botnet, which looks for vulnerabilities in network cameras, IP cameras, DVRs, and home routers.
“We have entered a new age of IoT device usage within the enterprise. Employees are exposing enterprises to a large swath of threats by using personal devices, accessing home devices, and monitoring personal entities through corporate networks,” said Deepen Desai, Vice President of Security Research, Zscaler. “As an industry, we need to implement security strategies that safeguard enterprise networks by removing shadow IoT devices from the attack surface while continuously improving detection and prevention of attacks that target these devices.”
Over the quarter, Zscaler blocked approximately 42,000 transactions which were IoT-based malware and exploits. The top malware families included Mirai, Gafgyt, Rift, Bushido, Demonbot and Pesirai. The top destinations connected to by IoT malware families and exploits are the United States, the UK, Russia, The Netherlands and Malaysia.
In response to the growing threat posed by Shadow IoT devices brought into the enterprise, IT organizations must first be able to gain visibility into the existence of unauthorized IoT devices that are already inside the network. Organizations should be considering a Zero Trust approach that ensures any communication between devices and people is with known entities and is within your organization’s policy to reduce the IoT attack surface.
