There have been 42.7 million attempted mobile malware attacks in 2017, says Kaspersky Lab Mobile Malware Evolution report. Overall the number of attacks on mobile devices has increased in 2017. However, a number of different types of mobile attacks, including rooting malware and mobile banking Trojans, have shown a declining trend. Rooting malware is still among the most popular types of malware, but it doesnt mean cyber criminals have given them up completely. The number of Android devices running older versions of Android 5.0 or older declined from more than 85% in 2016 to 57% in 2017; the proportion of Android 6.0 (or newer) users more than doubled.”]
