QUOTE:   The new NotCompatible: Sophisticated and evasive threat harbors the potential to compromise enterprise networks

A particularly nasty mobile malware campaign targeting Android users has hit between four million and 4.5 million Americans since January of 2013, according to an estimate by Lookout, a San Francisco mobile security company that has been tracking the malware for about two years.

Lookout first encountered the mobile malware, called NotCompatible, two years ago and has since seen increasingly sophisticated versions. Lookout said it believes, based on attempted infections of its user base of 50 million, that the total number of people who have encountered the malware in the United States exceeds four million.

The attackers goal, researchers say, is to infect as many smartphones as possible and turn them into a so-called botnet, a network of infected devices that can be used by attackers for various malicious purposes. Lookout’s researchers say there is evidence that Not Compatible’s authors are renting out control of infected mobile devices to people who have used them to simply send out more spam or buy up event tickets in bulk from from Ticketmaster, Live Nation, EventShopper and Craigslist. Some have used infected devices to try to crack WordPress accounts.
