Mastercard was the first credit-card company to come under attack by hackers, and attacks on Visa soon followed – both launched in retaliation for the companies’ refusal to process donations to WikiLeaks. At various points Wednesday, parts or all of their websites were down, MSNBC reported.
NPR reported Thursday that WikiLeaks’ payment processor, Iceland's DataCell ehf, is preparing to sue both companies for their decision to block the funds, which it claimed is costing the company money.
"It's difficult to believe that such a large company as Visa can make a political decision," [CEO Andreas] Fink said in a telephone interview from Switzerland. In an earlier statement, his company had defended the WikiLeaks, saying that "it is simply ridiculous to think WikiLeaks has done anything criminal."
