Does this classify as cyber-warfare?
The forces of Anonymous have taken aim at several companies who are refusing to do business with WikiLeaks. 4chan’s hordes have launched distributed denial-of-service attacks against PayPal, Swiss bank PostFinance, and other sites that have hindered the whistleblowing site’s operations.
A self-styled spokesman for the group calling himself “Coldblood” has said that any website that’s “bowing down to government pressure” is a target. PayPal ceased processing donations to the site, and PostFinance froze WikiLeaks founder Julian Assange’s account. The attacks are being performed under the Operation: Payback banner; Operation: Payback is the name the group is using in its long-running attacks on the RIAA, MPAA, and other organizations involved with anti-piracy lawsuits.
I think this is all pretty entertaining. However, I wish that a higher portion of the animosity was directed at the federal government, both for engaging in so many secret activities that they are horrified of us finding out about, and for actively pressuring private companies to avoid WikiLeaks.
