Cyber surveillance virus can spy on banking transactions and steal login and passwords. Gauss primarily infects 32-bit versions of Windows, though a separate spy module for USB drives can collect information from 64-bit systems. Infections are mainly split between Windows 7 and Windows XP, although some of the Gauss modules don’t work against Windows 7 Service Pack 1. The Gauss module is also capable of stealing data from clients of several Lebanese banks including the Bank of Beirut, EBLF, BlomBank, ByblosBank, FransaBank and Credit Libanais.
