According to Kaspersky Lab Antimalware Research group’s annual Mobile Virusology, compared to 2014, the volume of malwares targeting mobile devices grew more than thrice of which most dangerous were ransomware, malware capable of obtaining unlimited rights on an infected device and data stealers, including financial malware.
As per the research, the number of new malicious programs increased to 884,774 from 295,539 in 2014; the number of new mobile banking Trojans decreased to 7,030 from 16, 586 in 2014 and 94,344 unique users were attacked by mobile ransomware, a five-fold increase on 2014 (18, 478).
The number of ransomware, a type of malware which blocks an infected device with a pop up telling that the user has committed illegal action and unblocks it only after paying an amount between USD 12-100. The number of users of Kaspersky Lab mobile products attacked by ransomware is reported to be increased from 1.1% to 3.8% between 2014 and 2015.
Fraudsters use trojans through malicious web banners, games and other downloadable software to propagate to the user mobile device and gain the super-user access rights in order to get unlimited access to modify the data saved in the device. These malwares are hard to delete or uninstall even after factory reset of the device.
Similarly, a number of banking trojans are there which, after getting into client’s system/device, have the capability to overlay a bank’s legitimate pages or online payment apps with fake ones. The cyber-criminals can attack clients of dozens of banks located in different countries using only one type of malware, while previously they would have used malicious apps that could only attack one or two financial services organizations in just a few countries.
