Android is enjoying growth in every part of the world with more and more smartphones running on Android but this has also created concerns over mobile security as recent figures tells the whole story.  

In 2011 Android was responsible for 66 per cent of mobile malware but now the number has increased drastically specially in the fourth quarter of 2012. In the last quarter 6 new families and variants of Android threats were discovered.

According to the report Symbian was responsible for 19 per cent of the mobile malware in 2012 whereas it was 29 per cent in 2011. In 2010, Android was just responsible for 11 per cent for the malware but this percentage has increased drastically when it overtook Symbian as the world’s most used mobile OS.

Malware distributors usually send fraudulent SMS massages and according to F-secure some malware authors may choose to make money through bank Trojans by stealing the mobile Transaction Authentication Number (mTAN) which banks usually sends via SMS to their customers in order to confirm an online banking transaction.

“Malware in general has a parasitic relationship with its host,” F-Secure Labs security adviser Sean Sullivan said in a statement.
