Following, PayPal's, MasterCard has also pulled the plug on payments to WikiLeaks founder Julian Assange's account, a move that will dry up another source of funds for the embattled document-sharing Web site, CNET has learned.
"MasterCard is taking action to ensure that WikiLeaks can no longer accept MasterCard-branded products," a spokesman for MasterCard Worldwide said today.
In retaliation to this, 4Chan's launched distributed denial-of-service (DDOS) attacks against PayPal, Swiss bank PostFinance, and other sites that have hindered the whistleblowing site's operations.
A self-styled spokesman for the group calling himself "Coldblood" has said that any website that's "bowing down to government pressure" is a target. The attacks are being performed under the Operation Payback, which's organizing its WikiLeaks and Julian Assange support efforts through the @Anon_Operation Twitter account and here.
Attacks have also hit Paypal and Swiss bank PostFinance and other sites which have refused service to Assange. EveryDNS.net, Visa as well as Amazon are also possible targets.
Assange himself was arrested in London yesterday under allegations of sexual mis-conduct and will be held in custody until December 14th. Bail was refused over fears that he might flee, and also due to some fear that he was at risk from "unstable persons."
