No one knows what happened to the records during the next 3 years. But ultimate August, a geographically dispersed hacking collective based in Eastern Europe quietly commenced offering the complete database for sale, in keeping with Andrew Komarov, chief intelligence officer at InfoArmor, an Arizona cybersecurity company, who video display units the dark corners of the internet inhabited by way of criminals, spies and spammers. Three customers — two recognized spammers and an entity that regarded more interested in espionage — paid about $three hundred,000 every for an entire copy of the database, he stated.
