MADRID (AP) — Spanish authorities on Wednesday announced the breakup of a cybercrime gang that used a “ransomware” virus to lock computers throughout Europe, display false messages claiming the action was taken by police and demand payment of €100 ($135) to unlock the computers.

The gang, operating from the Mediterranean resort cities of Benalmadena and Torremolinos, made at least €1 million ($1.35 million) annually, said Deputy Interior Minister Francisco Martinez. Their notices to victims were accompanied by false threats claiming they were under investigation for accessing child pornography or illegal file-sharing.
