Bugat arrived on the scene in 2010 and was designed for data stealing and to specialize in web injection against Microsoft Internet Explorer and Mozilla Firefox users. The botnet produces about 2 percent of banking Trojans observed by Dell SecureWorks, falling in line with the IceIX, Gozi and Torpig botnets in terms of relative impact.

The malware uses a customized encryption routine that bolsters confidentiality and boosts efficiency, said Dell SecureWorks.
