The group of Russian hackers, dubbed APT28, is behind long-running cyber espionage campaigns that targeted US defense contractors, European security organizations and Eastern European government entities. The hackers also targeted attendees of European defense exhibitions, including the EuroNaval 2014, EUROSATORY 2014, and the Counter Terror Expo and the Farnborough Airshow 2014.
