chicksdaddy writes "A new malicious program that runs on Android mobile devices exploits vulnerabilities in Google's mobile operating system to extend the application's permissions on the infected device, and to block attempts to remove the malicious application, The Security Ledger reports. The malware, dubbed Backdoor.AndroidOS.Obad.a, is described as a 'multi function Trojan.' Like most profit-oriented mobile malware, Obad is primarily an SMS Trojan, which surreptitiously sends short message service (SMS) messages to premium numbers. However, it is capable of downloading additional modules and of spreading via Bluetooth connections. Writing on the Securelist blog, malware researcher Roman Unuchek called the newly discovered Trojan the 'most sophisticated' malicious program yet for Android phones. He cited the Trojan's advanced features, including complex code obfuscation techniques that complicated analysis of the code, and the use of a previously unknown vulnerability in Android that allows Obad to elevate its privileges on infected devices and block removal."
