Ice IX (Zeus family)
Ice IX is a modified variant of Zeus, the infamous banking Trojan, one of the most sophisticated pieces of financial malware out there.

This modified variant is used by cybercriminals with the same malicious purpose of stealing personal and financial information, such as credentials or passwords for the e-mail or the online bank accounts.

Like Zeus, Ice IX can control the displayed content in a browser used for online banking websites. The injected web forms are used to extract banking credentials and other private security information.

Ice IX, the modified version of Zeus, improved a few Zeus capabilities. The most important one is a defense mechanism to evade tracker sites, which monitor at present most Command and Control servers controlled by Zeus.
