Operation Payback, the rogue hacker network fighting stricter copyright laws, has launched a distributed denial of service attack (DDoS) against the Swiss bank PostFinance.
The attacks are in retaliation for the bank having frozen the main defense fund account for WikiLeaks' Julian Assange.
The same group also claimed responsibility for a DDoS attack against the PayPal blog earlier this week after PayPal suspended the WikiLeaks fund-raising account.
The Operation Payback Twitter account exclaimed, "We will fire at anyone that tries to censor WikiLeaks."
The bank issued a statement about the WikiLeaks account suspension that said, "Assange cannot provide proof of residence in Switzerland and thus does not meet the criteria for a customer relationship with PostFinance."
Next on the list may be EveryDNS.net, who revoked the WikiLeaks domain names last week, making the websites inaccessible by using the alphabetical URL's, though the sites remained online using the numerical IP addresses.
Operation Payback is a pro-piracy movement responsible for several denial of service (DoS) attacks against groups seeking stricter enforcement of copyright laws.
