Mobile ransomware is somewhat less common than ransomware on networks or machines, but the numbers are starting to climb. Security firm, Kaspersky Lab, reports four times as many users infected with mobile ransomware this year compared to last. In April 2015, 35,413 users we affected while in March 2016 that number increased dramatically to 136,532 users affected. The largest mobile ransomware detected is called Fusob, and has been responsible for 56 percent of the attacks during this past year, targeting Android users.
Fusob hides itself as a multimedia player called xxxPlayer…you can guess where this lies on the internet… and once downloaded Fusob blocks all user access to the device. Users are asked to pay in iTunes giftcards ranging between $100 and $200. Compared to the high demands of ransomware in the enterprise, these amounts sound like pennies. But to the user, that’s a hefty price to pay to get control of a device you should have never lost control of in the first place.
Interestingly, Kaspersky notes that much of the mobile ransomware out there right now does not actually encrypt any information on the users device. As most smartphone users usually backup to the cloud, there is no real point for hackers to actual encrypt the device. Instead hackers will encrypt applications so that users are blocked from the apps and will not be able to use the phone until paying the hackers.
Android users, be extra careful out there!!
