Android Malware Sees YOY Growth Of 270 Percent

Posted on May 16 2012 - 6:04am by Editorial Staff

A new data from security firm F-secure revealed that malware targeting Android users has nearly quadrupled since 2011. The number increased for two quarters in a row, then dipped for one, and then finally settled at 37 in Q1 2012, means a year-over-year growth of 270 percent. The trend was revealed today in the company’s 47-page Mobile Threat Report Q1 2012 (PDF). Here’s the corresponding excerpt:

Since its debut, Android has quickly claimed significant market share in the mobile market. Unfortunately, such popularity (amongst other factors) makes Android a lucrative target for malware authors. New families and variants of malware keep cropping up each quarter, and this trend shows no sign of slowing down. In Q1 2011, 10 new families and variants were discovered. A year later, this number has nearly quadrupled with 37 new families and variants discovered in Q1 2012 alone. A comparison between the number of malicious Android application package files (APKs) received in Q1 2011 and in Q1 2012 reveals a more staggering find — an increase from 139 to 3063 counts. This growth in number can be attributed to malware authors crafting their infected or trojanized applications to defeat anti-virus signature detection, distributing their malware in different application names, and trojanizing widely popular applications.

“The most interesting malware trend over recent months has been the increase in Trojans that deliver on their promises,” F-Secure analyst Sean Sullivan said in a statement. “This makes it harder for victims to know they have been victimised as there is less for them to detect.”
