Found most difficult in the world Trojan for Android

Android trojan

Employees of Kaspersky Lab detected a new malicious program for the operating system Android. Of the incident would not blow a lot of trouble if they found a trojan was not so “good”, his behavior is quite unlike the behavior of other viruses. Melver uses several vulnerabilities, blocking all attempts to uninstall, and also trying to take root, to allow the remote execution of commands. Backdoor.AndroidOS.Obad.a – the so-called the most complex computer virus for Android has ever seen experts on computer security.

Discovered two previously unknown vulnerabilities for Android, used Obad. In the setup file of the virus are modified file AndroidManifest.xml, which is part of any application for Android. The first serious vulnerability is in the handling of the file system. In theory, it should not even be handled by the system, but its installation runs smoothly.

Once inside the system, Obad floats its second Android-exploit that allows access to administrative rights. Becoming the “administrator Android», Obad receives the options available to most anti-virus applications. After executing the command you want to remove the virus is almost impossible, because it is not even in the approved list, the administrator is authorized to use the application.

Obad trojan

Settled in a mobile device virus begins to investigate the system, checking for Internet connectivity and access to system files. Upon detection of a free wireless network connection and establishes a trojan copies itself and other malicious applications to all connected devices.

In the Android-powered device Obad gets in encrypted form, which does not allow to convert some of the most important components in the original form, as long as the virus does not connect to the Internet. It is difficult to detect and further analysis. This Trojan does not even have an interface – the program runs completely in the background. The high level of complexity and new vulnerabilities make it look more like a virus for the operating system Windows, rather than for the mobile platform Android.

To date Backdoor.AndroidOS.Obad.a has a very restricted distribution, but quickly spreads around the world an alternative app store and phishing websites to warn of Kaspersky Lab. Google has already informed about the problem, which gives us hope for the elimination of critical vulnerabilities in the near future.
