A global, ever-expanding team of hackers called “Anonymous” has announced its next target in a series of cyberattacks that have taken down multiple websites over the past few days. Among its targets were the websites of both Visa and Mastercard following news that the institutions would cease delivery of funds that had been donated to WikiLeaks. Using Twitter to announce the attack, the group is preparing to take down Amazon.com, presumably due to the company’s abrupt cancellation of its hosting agreement with WikiLeaks after being pressured by the Department of Homeland Security.  The attack on Amazon.com will begin at 11:00am Eastern.
