Malicious mobile ad trojans decreased in 2017 – mobile ransomware doubled

According to the latest report by Kaspersky Lab, the security experts, the number of mobile malware threats declined in 2017. However, the Mobile Malware Evolution report highlighted that the overall volume of mobile malware attacks increased.
Kaspersky noted that there had been 42.7 million attempts of mobile malware attacks in 2017 – up from 40 million in 2016.
The overall variety of types of attacks however declined in 2017.
Mobile banking and advertising Trojans were lower.
Roman Unuchek, a senior malware analyst at Kaspersky Lab explained that the firm had expected a reduction in mobile ad Trojans “because of growth of share devices running newer Android versions.”

“These malware families are not related to non-mobile advertising malware,” he added.

Mobile ad Trojans were dominant in 2016 when they began to disrupt older Google Android operating systems. With the latest update to Android 6.0, this has been remedied slightly.
Meanwhile, mobile adware (a non-malicious type of ad software) also decreased in 2017 by 0.01%.
At the same time, mobile ransomware almost doubled in 2017, signalling a worrying trend. Although still uncommon, the top country now impacted by mobile ransomware is the US at 2%.
