MOSCOW, October 4 (RAPSI) – The Grand Jury forwarded the case of 13 alleged members of the international hacking group Anonymous to a court in Virginia, Associated Press reports on Friday.

The defendants were charged with participation in a DDoS attack that later came known to be as Operation Payback.

Those named in the indictment were Dennis Owen Collins, Jeremy Leroy Heller, Chen Zhiwei, Joshua Phy, Ryan Russel Gubele, Robert Audubon Whitfield, Anthony Tadros, Geoffrey Kenneth Commander, Austen Stamm, Timothy Robert McLain, Wade Carl Williams and Thomas Bell, according to an AFP report.

Anonymous became known in late 2010 after it carried out a series of attacks on the websites of companies and organizations which fought the recently exposed WikiLeaks document archive and disclosure resource. They also attacked the websites of the PayPal, Visa and MasterСard payment systems.

In May 2013, four alleged members of the group were arrested in Italy as a part of a major crackdown on the group.
