The increasing implementation of strong two-factor authentication has challenged fraudsters to develop new methods to target online users. One of the latest tactics being developed and deployed is the use of Trojans (also commonly known as malware or crimeware) to launch man-in-the-browser (MITB) attacks. A man-in-the-browser attack is designed to intercept data as it passes over a secure communication between a user and an online application. A Trojan embeds in a user's browser application and can be programmed to trigger when a user accesses specific online sites, such as an online banking site. Once activated, a man-in-the-browser Trojan can intercept and manipulate any information a user submits online in real-time. Read this whitepaper to learn how to deal with these insidious threats.
