A worrying update to the problem of ransomware on mobile phones appears to be proliferating in Ukraine and Russia, where Android users are being tricked into installing malware that encrypts photos and other information on their mobile phones.

The malware, which calls itself Simplelocker, presents itself to users as one of a variety of apps used to browse and view pornographic videos. We looked at 22 separate samples ranging in size from 30kb to 4.8MB. The app employs a range of different names on its installation screen, including DayWeekBar, VideoPlayer, VPlayer, or Sex xonix.
