A new and potent Android Trojan has already been leaked on several subway forums, so that it is available for free to less practical cybercriminals who are now likely to utilize it in attacks.

The Trojan application is known as SpyNote and allows hackers to steal users' messages and contacts, listen in on the calls, document sound using the device's built-in microphone, control the device camera, make rogue calls and more.

Based on researchers from Palo Enorme Networks, SpyNote does not require root access to a device, but really does prompt users for a long set of permissions on installation. The Trojan can also update itself and install other rogue programs on the device.

Is actually not clear yet how attackers plan to distribute it to victims, because experts haven't observed attacks in the wild using it. However, they think that such attacks are extremely likely providing that the SpyNote constructor is now available for free.

The builder is a Windows application that can be used to build custom-made versions of the malicious SpyNote APK (Android application package). Attackers can modify parameters like the app's name, icon and order server.

Most malicious Android applications are distributed from third-party websites and require devices to allow the installation of programs from "unknown sources. " This particular feature is deterred on Android devices automatically.

Coming from time to time, adware and spyware also slips through Google's defenses besides making its way to the state Play Retail store.

Another probability is guide installation of the Trojan's iphone app on an unsupervised device, for example by way of a jealous spouse, a business partner, or an ill-intended colleague. There have been cases where users have received pre-infected devices as gifts from people who wished to spy on them.

Newer versions of Android have antimalware features like Verify Apps and SafetyNet that can identify and block known adware and spyware applications when their unit installation is attempted and even if "unknown sources" is allowed on the device.

As a general principle, "installing applications from thirdparty sources can be extremely risky -- those sources often shortage the governance provided by official sources including the Google Play Store, which, even with detailed procedures and algorithms to disregard destructive applications, is not impregnable, " the Palo Enorme Networks researchers said in a blog post. "Side-loading programs from questionable resources exposes users and their mobile devices to a variety of malware and possible data loss. "
