Report: Android malware up 3,325% in 2011

29 Feb

Summary: Android malware samples had increased from 400 to 13,302 in six months.

Everything has its own value. In 2011, there was an ‘unprecedented growth’ of mobile malware attacks, with Android up a stratospheric 3.325 percent, according to a report by the Juniper Networks Mobile Threat Center.

The report shares stressing news. Comparing all platforms, mobile malware attacks are up 155 percent, with mobile malware samples increasing from 11,138 in 2010 to 28,472 in 2011. BlackBerry malware grew by 8 percent, and Java ME saw a 49 percent increase. But the platform hit hardest was Android, with malware increasing by an incredible 3,325 percent in a year. During the last six months of 2011, Android malware samples had increased from 400 to 13,302.

Spyware stood top as the most popular Android malware, numbering 63 percent, meanwhile 36 percent were premium rate SMS Trojans. And 30 percent could obtain location information without user acceptance and 14.7 percent of them are capable to make calls behind the users’ back.

The report also notes that malware is becoming more sophisticated, with malware like Droid KungFu using encrypted payloads to avoid detection and Droid Dream disguising itself as a legitimate app.

Security guru Bruce Schneier isn’t surprised. ‘I don’t think this is surprising at all,’ wrote Schneier in a blog post. ‘Mobile is the new platform. Mobile is a very intimate platform. It’s where the attackers are going to go.’

Google’s Finally Cracking Down on Android Malware

3 Feb

Google has announced a new security mechanism, a new feature to the Android Market named Bouncer, which will scan the available apps for malware without troubling developers or interfering with user experience at all.

Bouncer, wrote Android engineering VP Hiroshi Lockheimer on the company blog, “provides automated scanning of Android Market for potentially malicious software without disrupting the user experience of Android Market or requiring developers to go through an application approval process.”

Bouncer works on a few levels. When a new app proceeds, they are analyzed to see if any malware, spyware and trojans are carried in with them.  It also makes an comparison of the operation of the app, how is it compares to similar apps that have been problems in the past. And finally, it analyzes new dev accounts to see if they’re just old malware hawkers coming back around (how that last part works is less clear).

It sounds like a great step toward ridding the Market of problem apps, and seems to be working so far. It’s been in effect for “a while now,” and while there’ve been a number of high profile alarms over the past several months, Google claims there was a 40 percent drop in malware activity from the first to the second half of 2011. Do with that what you will, but in any case, a more secure Android Market is only good news. [Google]
