Agent Smith is a mobile malware which has infected approximately 25 million smartphones across the world out of which 15 million devices are estimated to be from India. It accesses the smartphone's resources to show fraudulent ads for financial gains, however, it could be easily used for much more intrusive and harmful purposes like theft of banking credentials and secretly listening to conversations. The malware which is disguised as a Google-related application exploits the known vulnerabilities of Android and replaces apps installed with their malicious versions without the knowledge of the user. This activity resembles some previous malware campaigns such as Gooligan, Hummingbird, and CopyCat. There has also been a noticeable number of infected smartphones in the UK, Australia, and the US.
