Wikileaks defended by Anonymous hacktivists Mastercard 'hit by Wikileaks revenge attacks'
(about 21 hours later)
Internet hacktivists have fired the latest salvo in the Wikileaks infowar. Internet hacktivists are claiming to have brought down the Mastercard website as revenge for the firm withdrawing services to Wikileaks.
A group called Anonymous has hit sites that have refused to do business with the controversial whistle-blowing site with a series of distributed denial-of-service attacks. The Anonymous group of hackers have also brought down the website of the Swedish prosecutors office which is pursuing founder Julian Assange.
It mirrors similar attacks aimed at the Wikileaks site. It has pledged to launch denial-of-service attacks on websites it sees as anti-Wikileaks.
Targets include the Swiss bank that froze founder Julian Assange's assets and PayPal which has stopped processing donations to Wikileaks. Earlier it hit the Swiss bank that froze Mr Assange's assets.

"We are glad to tell you that Mastercard is down and it's confirmed," the group tweeted.
Mastercard has not yet confirmed the attack but security experts have said the site has been under a so-called distributed denial-of-service attack (DDoS), which swamp a site with so many requests that it becomes overwhelmed,
However, access appears to be possible intermittently and it is still visible from some countries, experts say.
Earlier the group confimed other targets: "In response to the arrest of Julian Assange, Anoynmous has taken down PostFinance.ch, who terminated Wikileaks bank account, using a distributed denial-of-service attack. Subsequently, Anonymous attacked http://www.aklagare.se, the Swedish Prosecutors office, also using a DDoS attack, and took the site down in under 10 seconds of beginning the attack," the group said in a statement.
Noa Bar Yosef, a senior analyst at security firm Imperva said the attacks are "very focused".
"It is recruiting people from within their own network. They are actually asking supporters to download a piece of code, the DDosing malware and upon a wake-up call the computer engages in the denial of service," he said.
