U.S. and European law enforcement officials said on Thursday that they had dismantled a global organized cybercrime network, which used malware to steal banking login details in an attempt to pocket about $100 million from thousands of businesses.

A federal grand jury in Pittsburgh charged 10 members of the network, and other criminal prosecutions have begun in Georgia, Moldova, and the Ukraine, the European Union's (EU's) agency for law enforcement cooperation Europol said in a statement. Five Russian nationals charged in the indictment are on the run, the agency said, including the developer of the malware.

In what Europol called a “highly specialized and international criminal network,” the members—spread across Georgia, Moldova, Bulgaria, Ukraine, and Russia—sent spear-phishing emails to infect computers with malware, dubbed GozNym, designed to capture login details. That allowed the members to steal money from the bank accounts and launder the funds using U.S. and foreign bank accounts.
