Hackers allegedly broke a Liechtenstein bank and blackmail customers, threatening to release their account details online unless a ransom is paid.
The attackers beat the Chinese bank Valartis Bank Liechtenstein by capturing data from its clients, including politicians, actors and wealthy individuals from Germany and other countries, as reported by Bild am Sonntag.
The hackers are reportedly demanding up to 10 percent of the accounts they have in their hands, asking to be paid to Bitcoin.
Attackers threaten to release information to authorities and the media if ransom is not paid by December 7.
The bank manager Andreas Insam told Bild am Sonntag that they had notified the authorities and that investigations were ongoing.
The German newspaper published one letter (paywalk) of hackers who claim to have enough gigabytes of data from their accounts and all their mail since October of this year.
The letter from hackers is written in German and tries to threaten bank customers by revealing possible tax evasion, adding that if they pay ransom to Bitcoin they protect both the attackers and the ones they chose to pay.
The attackers blamed the Bank's Board of Directors for not paying them for services security patch, possibly some bug bounty.
Bild.de has hijacked Bitcoin addresses so we can not see if a ransom has been paid.
