Abstract

Information stealing and banking trojans have become the tool of choice for cyber criminals for various kinds of cyber fraud. Traditional security measures like common antivirus solutions currently do not provide sufficient reactive nor proactive detection for this type of malware. In this paper, we propose a new approach on detecting banking trojan infections from inside the web browser called Banksafe. Banksafe detects the attempts of illegitimate software to manipulate the browsers‘ networking libraries, a common technique used in widespread information stealer trojans. We demonstrate the effectiveness of our solution with evaluations of the detection and classification of samplesets consisting of several malware families targetting the Microsoft Windows operating system. Furthermore we show the effective prevention of possible false positives of the approach.
