MADRID (AP) — Spain's National Court has recommended the extradition to the United States of a Russian computer programmer accused by U.S. prosecutors of developing malicious software that stole information from financial institutions and caused losses of $855,000.

Stanislav Lisov, 31, was arrested Jan. 13 in the Barcelona Airport while on honeymoon in Europe. Prosecutors accuse him of developing the NeverQuest software that targeted banking clients in the United States between June 2012 and January 2015.

The Spanish court said Tuesday that Lisov could face up to 25 years in prison for conspiracy to commit electronic and computer fraud. The extradition hearing took place July 20.

The court said its ruling can be appealed by Lisov.

The extradition, if finally decided upon, must be approved by the government.
