An analysis of the technologies used by cybercriminals allows us to draw conclusions about the virus industry’s possible vectors of development and more effectively confront future threats. You, too, can learn what actions various malicious programs take in infected systems and how to withstand them.
A family of malicious programs for Android mobile devices. Android.Tempur Trojans are distributed in the guise of online banking applications. Their main purpose is to steal confidential data used by the clients of some South Korean financial organizations.
Once such a Trojan infects a device, it scans the system for the presence of online banking applications and, if the search returns positive result, attempts to uninstall them. Due to the fact that these malicious programs imitate the interface of legitimate banking applications, inexperienced users can fall victim to the malware entering their confidential information into the fake authentication form. Depending on the modification, these Trojans can ask the user to enter various confidential information (for example, username, personal ID, social insurance number, account password, bank account number, phone number, and so on). Moreover, the malware can intercept incoming SMS messages and send short messages to premium numbers.
Cybercriminals can distribute these programs by sending unsolicited SMS messages containing a link to download these Trojans or by using some other malware.
According to statistics, every fifth program for Android contains a vulnerability (or, in other words, a "loophole") that lets cybercriminals successfully introduce Trojans onto mobile devices and manipulate them into doing whatever actions they need them to.
