Russian authorities have nabbed a gang of 20 people allegedly behind the Carberp banking trojan, according to a report.
Moscow-based Kaspersky Lab researcher Aleks Gostev said the arrested men had helped develop the Carberp malware.
Russia's Kommersant newspaper cited the Security Service of Ukraine and the Russian Federal Security Service as stating the accused fraudsters operated since 2009.
The group stole $250 million from Ukraine and Russian bank accounts alone by funneling the cash into the accounts run by shell companies. Accounts in the United States and Canada were hit.
As recently as December, Carpberp fetched $40,000 per kit. The defendants ranged from 25 to 30 years of age and worked remotely to help the malware evade anti-virus detection.
Last year, authorities charged a 22-year-old Russian man with using a modified version of Carberp to steal login details and digital signatures from compromised computers.
