Mobile malware increasing

Mobile malware is a continuing concern for users, as the discovery of OBAD and the subsequent media coverage) shows. Just like Windows malware, mobile malware are also becoming more sophisticated, both in technique and deployment. This confirms one of Trend Micro's2013 security predictions.

OBAD exploits an Android vulnerability to avoid detection and uninstallation. OBAD’s propagation method is notable because of its use of Bluetooth, a routine previously seen in Symbian malware.

As reported earlier, one means of transport is with Fake AV apps. FAKEAV mobile malware routines now include pop-up windows and messages about “infected” apps. Rather than show persistent notifications, mobile ads now lead users to web threats.

Android vulnerabilities are exploited because Android fragmentation makes it difficult to address vulnerabilities. This concern on Android’s update issues may contribute to the growing concerns about mobile malware, making it easy for users to become victims of mobile FAKEAV.

Trend Micro's latest monthly mobile report discusses these emerging threats, issues affecting or influencing these threats, and what you can do to help secure your devices better.
