Hackers have attacked MasterCard's website in protest of the company's blockade of WikiLeaks.
"MasterCard.com DOWN!!!, thats what you get when you mess with @wikileaks @Anon_Central and the enter community of lulz loving individuals :D," tweeted @ibomhacktivist, who seems to be connected with the hacker collective Anonymous.
Though MasterCard's site is currently online, there are reports that it was completely offline at one point due to the DDoS (distributed denial of service) attack.
In December 2010, hackers took down Mastercard's website, along with Postfinance and PayPal, for the exact same reason: a WikiLeaks blockade.
Shortly after the attack on MasterCard, WikiLeaks acknowledged on its official Twitter account that several banks still won't do business with the organization. "The unlawful banking blockade against WikiLeaks in 6th month: The culprits: VISA, MasterCard, PayPal, Bank of America, Western Union," said the tweet.
LulzSec, the hacker group that wreaked havoc on corporate and government websites in the past two months, recently disbanded. However, the Anonymous hacktivist collective vowed to continue their hacking activities, and we can already see proof that they weren't kidding.
