The report examined general trends and statistics for infections in devices connected through mobile and fixed networks around the world.

The report outlined a steady increase in mobile device infections throughout 2016, with malware striking 1.35% of all mobile devices in October - the highest level seen since reporting started in 2012.

This revelation comes at a time when smartphone penetration has been increasing in India and the government has been pushing for digital transactions using smartphone phones.

While Android-based smartphones and tablets continued to be the primary targets (81%), reflecting the prevalence of the operating system worldwide, iOS-based devices also suffered attacks in the second half of the year (4%), primarily by Spyphone surveillance software that tracks users' calls, text messages, social media applications, web searches, GPS locations and other activities.

The Threat Intelligence Report also exposed major vulnerabilities in the rapidly expanding universe of IoT devices, underscoring the need for the industry to re-evaluate its IoT deployment strategies to ensure these devices are securely configured, managed and monitored.

“In late 2016, the Mirai botnet assembled an army of compromised IoT devices to launch three of the largest DDoS attacks in history, including an assault that took down many high-profile web services. These attacks underscored the urgent requirement for more robust security capabilities to protect IoT devices from future attacks and exploitation,” said the report.

There was a decrease in Windows or PC infections as it accounted for 15% of malware infections in the second half of 2016, down from 22% in the first half of the year.

The monthly infection rate in residential fixed broadband networks averaged 10.7% in the second half of 2016, down from 12% in the first half, and down from 11% in late 2015. While moderate threat level adware activity decreased in the second half of 2016, high-level threats (eg, bots, rootkits, keyloggers and banking Trojans) remained steady at approximately 6%.
