MOSCOW, August 1 (RAPSI) – Spain’s National High Court ruled on Tuesday to extradite Russian programmer Stanislav Lisov, suspected of developing NeverQuest malware, to the United States, the court announced on Tuesday.

Damage allegedly caused by Lisov’s actions is estimated at $5 million.

According to the Civil Guard, the arrested Russian national is one of the most important Russian hackers wanted by the U.S.

Investigation into Lisov was launched in 2014. He allegedly conspired with a group of people to develop, distribute and use malicious software NeverQuest which steals bank account logins and gives attackers access to accounts through computers of victims. Lisov is supposed to be the creator and administrator of a network of computers infected with NeverQuest via servers he had leased and acquired.

The study of servers operated by the suspect in Germany and France afforded to find out databases containing information stolen from banking institutions including account balances, the Civil Guard reported. One of the servers allegedly used by Lisov contained millions of login credentials, in particular user names, passwords and review quiz answers to access online bank and financial accounts.

As reported earlier, Lisov was arrested in Spain in January on the request of Interpol and Federal Bureau of Investigation (FBI).

The Russian embassy was officially notified of Lisov’s arrest. Russia has forwarded a request to the Spanish authorities seeking to inform about reasons and details of the arrest.

Lisov, the resident of the city of Taganrog, is engaged in support and development of websites in Russia, according to his wife. The spouses went to Spain on vacation.

In October 2016, Russia was accused of organizing hacking attacks against the U.S. election systems. However, American authorities presented no evidence of Russia’s involvement in cyberattacks allegedly aimed to affect the presidential election results in the U.S.
