An anonymous reader writes "Almost a third of all mobile malware is made by 10 Russian organizations, according to Lookout Mobile Security. It made that claim after looking at its detections for this year, and after an investigation that uncovered the malware HQs' operations, which saw thousands of affiliates working alongside the factories to dupe users into downloading rogue apps. Those apps are fairly crude, sending SMS messages to premium rate numbers in the background, whilst users think they have downloaded a legitimate application. Lookout isn't revealing the names of the malware factories, however, nor is it divulging how far law enforcement are involved in cracking down on the Russian organizations. It is presenting its full findings at the DEF CON 21 conference."
