Trojan-Banker.AndroidOS.Faketoken

Parent class: TrojWare

Trojans are malicious programs that perform actions which are not authorized by the user: they delete, block, modify or copy data, and they disrupt the performance of computers or computer networks. Unlike viruses and worms, the threats that fall into this category are unable to make copies of themselves or self-replicate. Trojans are classified according to the type of action they perform on an infected computer.

Class: Trojan-Banker

Trojan-Banker programs are designed to steal user account data relating to online banking systems, e-payment systems and plastic card systems. The data is then transmitted to the malicious user controlling the Trojan. Email, FTP, the web (including data in a request), or other methods may be used to transit the stolen data.

Platform: AndroidOS

Android is an open-source operating system developed by Google for mobile devices, such as tablets, smartphones, and watches. Based on a Linux kernel and the Dalvik virtual machine (older versions) / Android Runtime environment (newer versions).

Description

Malware in this family steals a user's one-time banking password and is used in combination with Trojans. When the user is logged in to an online bank, the Trojans inject code into the web page. The web browser window, which is displaying the page of the online bank, asks the user to download an Android app. The user is falsely informed that the app is necessary for making safe banking transactions, and the page is modified to display a link to the Faketoken Trojan. When the downloaded malware is run on the user's smartphone, the cybercriminal uses the malware to obtain access to the user's bank account. Faketoken enables the cybercriminal to intercept one-time mTAN (mobile transaction authentication number) codes and transfer the user's money to other accounts. Malware in this family was first identified in late March 2013.
