This is due to the fact that Android-based devices can\u2019t remove screen lockers with help of external hardware, making mobile screen blockers as effective as PC crypto-ransomware.<\/span><\/p>\n<\/li>\n<\/ul>\n<p dir=\"ltr\"><span style=\"color: #000000;\">Although the actual number of users attacked with ransomware is lower and the rate of growth slower than that seen for <a href=\"http:\/\/www.kaspersky.com\/about\/news\/virus\/2016\/Crypto-ransomware-Attacks-Rise-Five-fold-to-Hit-718-Thousand-Users-in-One-Year\" target=\"_blank\" rel=\"nofollow\">PC ransomware<\/a>, the situation with Android ransomware is still worrying. <\/span><\/p>\n<p id=\"yui_3_16_0_ym19_1_1468205737298_136791\" dir=\"ltr\"><span style=\"color: #000000;\">At the start of the comparison period, the monthly number of users who encountered this type of malware on Android devices was almost zero, but by the end it had reached nearly 30,000 attacked users per month.<\/span><\/p>\n<p id=\"yui_3_16_0_ym19_1_1468205737298_136794\" dir=\"ltr\"><span id=\"yui_3_16_0_ym19_1_1468205737298_136793\"><span id=\"yui_3_16_0_ym19_1_1468205737298_136792\" style=\"color: #000000;\">This clearly indicates that criminals are actively exploring alternative opportunities to the PC and show no signs of moving on. <\/span><\/span><\/p>\n<p id=\"yui_3_16_0_ym19_1_1468205737298_136788\" dir=\"ltr\"><span id=\"yui_3_16_0_ym19_1_1468205737298_136790\" style=\"color: #000000;\"><span id=\"yui_3_16_0_ym19_1_1468205737298_136789\">\u201cThe extortion model is here to stay. Mobile ransomware emerged as a follow-up to PC ransomware and it is likely that it will be followed-up with malware targeting devices that are very different to a PC or a smartphone. These could be connected devices like smart watches, smart TVs, and other smart products including home and in-car entertainment systems. There are a few proof-of-concepts for some of these devices, and the appearance of actual malware targeting smart devices is only a question of time,\u201d<\/span> said Roman Unuchek, mobile security expert at Kaspersky Lab.<\/span><\/p>\n<p dir=\"ltr\"><span style=\"color: #000000;\">In order to protect yourself from mobile ransomware attacks, Kaspersky Lab advises the following measures:<\/span><\/p>\n<ul>\n<li dir=\"ltr\">\n<p dir=\"ltr\"><span style=\"color: #000000;\">Restrict the installation of apps from sources other than official app stores.<\/span><\/p>\n<\/li>\n<\/ul>\n<ul>\n<li dir=\"ltr\">\n<p dir=\"ltr\"><span style=\"color: #000000;\">Use a reliable security solution capable of detecting malware and malicious web links.<\/span><\/p>\n<\/li>\n<\/ul>\n<ul id=\"yui_3_16_0_ym19_1_1468205737298_136801\">\n<li id=\"yui_3_16_0_ym19_1_1468205737298_136800\" dir=\"ltr\">\n<p id=\"yui_3_16_0_ym19_1_1468205737298_136799\" dir=\"ltr\"><span style=\"color: #000000;\">If installing apps from non-official sources is unavoidable, keep an eye on what permissions the app is requesting.
