Gafgyt and Mirai were the two most commonly found malware families, with most traffic coming from devices in the manufacturing and retail industries.
There has been 700% more malware attacks detected against Internet of Things (IoT) devices during the pandemic, new research has suggested. A report from cloud security firm Zscaler analyzing more than 575 million device transactions and 300,000 IoT-specific malware attacks blocked by the company found that attackers were focused on roughly 550 different device types. Printers, digital signage and smart TVs, all of which were connected to corporate IT networks, were particularly affected, with smart refrigerators and musical lamps even found to be connected and transmitting data through corporate networks. Overall, Zscaler found a total of 553 devices from 212 manufacturers were targeted. Almost two-thirds (63%) of them fell into three categories: set-top boxes, smart TVs, and smartwatches.
