AntiSec, the hacker movement that emerged out of the now disbanded Lulz Security and bolstered by Anonymous, is too following tradition by going after PayPal for withholding funds from WikiLeaks. However this time they took an uncharacteristic course of action–a “DBoS” or Distributed Boycott of Service attack. Rather than breaching the company’s site, AntiSec posted an open letter on Pastebin encouraging users to close their PayPal accounts in protest to the company’s actions.

The letter reads:

“We encourage anyone using PayPal to immediately close their accounts and consider an alternative. The first step to being truly free is not putting one’s trust into a company that freezes accounts when it feels like, or when it is pressured by the U.S. government.”

This open call is unlikely to drive a sizable portion of PayPal’s 100 million users away from the service, and it’s not the first attempt by a hacktivist group to protest against companies that blocked service to WikiLeaks. Amazon, Visa and PayPal all banned WikiLeaks last year. The response was Operation Payback, a targeted hacking campaign that established a presence on Facebook and Twitter–one which was removed from the two social networks shortly after it has started.

Going back to AntiSec’s letter, it’s important to note that it was also meant to serve more than one purpose. The group used the letter as an opportunity to respond to the fairly effective crack down on its members that has been taking place in recent weeks. There have been 16 arrests in the U.S so far; 14 in California, one in New Jersey and another in Florida. Over at the U.K. the London Metropolin police caught its biggest fish so far–a 19-year-old male suspected to be the LulzSec hacker calling himself Topiary.
