An international cybercrime network that used Russian malware to steal $100 million from tens of thousands of victims have been busted by the joint operation of Unites States and European police. The gang used an extremely powerful GozNym banking malware to infect the computers which allowed them to steal the user’s bank login details, it involves "more than 41,000 victims, primarily businesses and their financial institutions," Europol said. The malware GozNym is a combination of two other malware — Gozi and Nymaim. According to the IBM X-Force Research team the malware took the most powerful elements of each one. “From the Nymaim malware, it leverages the dropper’s stealth and persistence; the Gozi parts add the banking Trojan’s capabilities to facilitate fraud via infected internet browsers,” the team said, adding: “The end result is a new banking Trojan in the wild.” The prosecutions have been launched against the gang in Georgia, Moldova, Ukraine and the United States. While five Russians charged in the US remain on the run, the EU police agency Europol said. Alexander Konovolov, 35, of Tbilisi, Georgia, is a prime accused and the leader of the network, and is currently being prosecuted in Georgia. Police in Germany and Bulgaria were also involved.
