What may be the largest ever malware campaign against Android users have been uncovered. The malware discovered was packaged in 13 different apps from three different publishers, and found in Android Market. Dubbed “Android.Counterclank” by Symantec, the attack seems to take a different tactic compared to the more common “repackaging method”. This practice involves repackaging a legitimate app with attack code, then re-release it to the marketplace in the hope that users will confuse the infected version with the real deal. “These aren’t rebundled apps, as we’ve seen so many times before” said Kevin Haley, a director with Symantec‘s security response team.
The 13 different applications have titles ranging from “Sexy Girls Puzzle” to “Counter Strike Ground Force”, and many of the infected apps were still available on the Android Market as of 3 p.m. ET Friday. Symantec estimated the impact by combining the download totals of the 13 apps, arriving at a figure between 1 million on the low end and 5 million on the high. “Yes, this is the largest malware outbreak on the Android Market” said Haley.
