PWS-Gauss is a malware toolkit for the purpose of data collection. Similar to Stuxnet and Flame, Gauss comprises of a multiple module framework that work together to carry out attacker functionality. Several modules seem to derive their names after famous mathematicians and hence the name Gauss.
Modules may include browser plugins, USB infections, Java Script and other ActiveX controls. The objective of Gauss is to collect several points of system information as well as credentials for email, domain accounts, social networks and banking information. Each module is designed to collect different types of data. The USB module in particular uses a previously-known exploit (CVE-2010-2568) in a tactic similar to that used by the Stuxnet/Duqu worms.
PWS-Gauss modules may contain several components, including:
