Google's mobile platform, Android, is increasingly becoming a key target for cybercriminals implementing malware.
According to a report from web security firm Blue Coat Systems, it found that 58 percent of Android malware is root exploits and rogue software. Android malware through malnets, which are networks that integrate malicious payloads, accounted for 40 percent of the total.
"The Android-based malware blocked by WebPulse included an Android root exploit and a variety of rogue Android software," Blue Coat noted. "Forty percent of Android malware was delivered via malnets, demonstrating how cybercriminals can successfully utilize embedded infrastructures to attack mobile users. In the most recent six months, WebPulse also blocked an increasing number of unique malicious Android applications."
The study also found that pornography is a key threat for Android mobile devices, but mobile users are said to visit porn sites less than 1 percent of the time.
Due to wireless phone carriers and handset manufacturers failing to launch existing software security fixes to devices within an acceptable time frame (some take at least a year), millions of Android smartphones are left vulnerable.
During the third quarter of 2012, the amount of Android malware increased by a significant proportion. A recent exploit, meanwhile, utilizes a user's own PC microphone to record victims.
