Ice IX


The ICE IX bot is a banking trojan derived of the Zeus botnet because it uses significant parts of Zeus’s source code. ICE IX communicates using the HTTP protocol, so it can be considered to be a third-generation botnet. While it has been used for a variety of purposes, a primary threat of ICE IX comes from its manipulation of banking operations on compromised machines. As with any bot, execution of the bot results in establishing a master-slave relationship between the botmaster and the compromised computer.
