Attackers hit the Website for MasterCard in an apparent cyber-retaliation for the company's decision to stop processing donations to WikiLeaks.
MasterCard joined a growing list of companies targeted by hacktivists associated with Anonymous, a loosely affiliated group tied to the 4chan message board. The attack was confirmed in a tweet this morning by user @Anon_Operation: "WE ARE GLAD TO TELL YOU THAT http://www.mastercard.com/ is DOWN AND IT'S CONFIRMED! #ddos #wikileaks Operation:Payback(is a b***h!) #PAYBACK."
MasterCard has said it decided to cancel its business with WikiLeaks because the company's rules prohibit customers from directly or indirectly engaging in or facilitating criminal behavior. The credit card company has become the latest in a string of companies and institutions being targeted in retaliation for recent actions against the site.
On Dec. 7, attackers struck back at the Swedish prosecutor by launching a denial-of-service (DoS) attack on www.aklagare.se, making it impossible to access the site until recently. Swedish authorities pushed for the arrest of WikiLeaks founder Julian Assange, who was taken into custody in the U.K. earlier this week on sexual assault charges.
