Remote access tools have long been a major part of targeted hacker attacks on individuals and corporate networks. RATs have been used for everything from hacking the e-mail boxes of New York Times reporters to capturing video and audio of victims over their webcams. Recently, wireless broadband and the power of smartphones and tablets have extended hackers’ reach beyond the desktop. In a blog post yesterday, Symantec Senior Software Engineer Andrea Lelli described the rise of an underground market for malware tools based on Androrat, a remote administration tool that can give an attacker complete control over devices running the Android OS.
Androrat was published on GitHub in November 2012 as an open source tool for remote administration of Android devices. Packaged as a standard Android application (in an APK file), Androrat can be installed as a service on the device that launches at start-up or as a standard “activity” application. Once it’s installed, the user doesn’t need to interact with the application at all—it can be activated remotely by an SMS message or a call from a specific phone number.
The app can grab call logs, contact data, and all SMS messages on the device, as well as capture messages as they come in. It can provide live monitoring of call activity, take pictures with the phone’s camera, and stream audio from the phone’s microphone back to its server. It can also post “toasts” (application messages) on the screen, place phone calls, send text messages, and open websites in the phone’s browser. If it is launched as an application (or “activity”), it can even stream video from the camera back to the server.
