Android platform most popular for malware
Kaspersky Lab discovers 30% increase in new malware created for Android OS in September
The Android platform is now the most popular for malicious mobile programs, overtaking other platforms and Java malware, according to Kaspersky Lab.
September 2011 saw a 30% increase in new malware created for Android-based devices and increasingly this new mobile malware is created to steal personal data. In October 2011 the share of Android malicious apps trying to steal personal data went up to 34%.
One example of a malicious app distributed through the official store is Trojan-Spy.AndroidOS.Antammi.b, which masquerades as a simple app for downloading ringtones and appeared on Android Market. The malicious app was removed after notification from Kaspersky Lab.
The malicious app is designed for users in Russia, who use it to send text messages to a paid service to receive back desired tunes, but malicious payload activity is simultaneously going on in the background. Antammi.b steals almost everything: contacts, texts, GPS coordinates and even photos. The activity log is then sent to the criminal behind the scam via a simple e-mail message, and the data is uploaded to a server.
Apart from stealing personal data, sending texts, and making calls to premium numbers, mobile malware is also targeting banking services, which often send one-time passwords and confirmation codes to mobile phones.
The share of Android-based malicious programs among all mobile malware is currently higher than 46%, and growing rapidly, according to Kaspersky.
