Visa, MasterCard targeted in apparent cyberattack

[Updated at 5:15 p.m.] The corporate websites of Visa and MasterCard
were inaccessible at times Wednesday due to an apparent cyberattack by purported Wikileaks backers.

Messages posted on Twitter indicated the attacks may be in response to recent moves by Visa and MasterCard against WikiLeaks, the website that recently released thousands of secret U.S. State Department documents.

"The issue appears to be the result of a concentrated effort to flood our corporate website with traffic and slow access," said MasterCard spokesman James Issokson, in a prepared statement. "We are working to restore normal service levels."

MasterCard and Visa Europe, a division of Visa, had said they were working to stop the acceptance of their cards on WikiLeaks.

    The attacks are actually greatly supported by the 4chan.org message board. The attacks are meant to send a message that the internet community is disgruntled about the fact that the government is censoring their internet media. As far as I can see, the message was heard loudly

    They shouldn't have tried to block a legal defense fund for lame politics. Visa and MC earned it.

    The censorship of the us government e.g. influence to companies is against freedom and can be compared to the censorship of china. Free USA has been yesterday

      When doing a DDOS attack, you attack a website using programs such as LOIC (Low Orbital Ion Cannon0 and the word Fire is basically pointing the program to the site. Firing a cannon you could say.
