Gauss highly modular architecture reminds us of Duqu — it uses an encrypted registry setting to store information on which plugins to load; is designed to stay under the radar, avoid security and monitoring programs and performs highly detailed system monitoring functions. In addition, Gauss contains a 64-bit payload, together with Firefox-compatible browser plugins designed to steal and monitor data from the clients of several Lebanese banks: Bank of Beirut, EBLF, BlomBank, ByblosBank, FransaBank and Credit Libanais. In addition, it targets users of Citibank and PayPal.
