According to Kaspersky Lab Antimalware Research, the volume of malware targeting mobile devices grew more than threefold in 2015 over the previous year. Ransomware, malware that obtains unlimited rights on a device, and data stealers such as financial malware served as significant threats. “The number of ransomware app modifications has increased by 3.5 times, proof that fraudsters are seeing ever more advantage in earning money from users via blackmail,” notes Network World. “2016 is likely to see an increase in the complexity of the malware and its modifications, with more geographies targeted.”
