An online group calling itself Anonymous is attacking sites around the web perceived to be "enemies" of WikiLeaks and its founder, Julian Assange. This appears to be the group responsible for the shutdown of the Mastercard site earlier today, owing to Mastercard's refusal to process payments to the group. After the site went down, the group posted a statement that read in part:
We will fire at anything or anyone that tries to censor WikiLeaks, including multibillion-dollar companies such as PayPal.
Twitter, you're next for censoring #WikiLeaks discussion. The major shitstorm has begun.
Other targets that have already been targeted, or threatened with attack, range from Sarah Palin to Sen. Joe Lieberman to PayPal, the last of which recently admitted to bowing to U.S. pressure to break ties with the site.
