Zscaler Annual IoT Report Identifies Shift in Shadow IoT Behavior Threatening Enterprise Security Posture

February 25, 2020 Tiera Oliver

Zscaler released its second annual Internet of Things (IoT) report "IoT Devices in the Enterprise 2020: Shadow IoT Threat Emerges". According to the company, Zscaler customers are now generating more than one billion IoT transactions monthly in the Zscaler cloud. This amounts to a 1,500% increase since Zscaler’s May 2019 report. Analyzing two weeks of this traffic through Zscaler cloud, it found 553 different IoT devices across 21 categories from 212 manufacturers.

Organizations globally are observing this shadow IoT phenomenon, where employees are bringing unauthorized devices into the workplace. With the influx 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.

Key Findings:

● Unauthorized IoT Devices on the Rise 

● Manufacturing & Retail Industries Top IoT Traffic Volume

● Majority of IoT Transactions are Insecure

● Exponential Increase of IoT Malware

● New Exploits Emerging to Target Unauthorized Devices

Throughout this 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 the IoT threats are the United States, the UK, Russia, The Netherlands, and Malaysia.
