Revision3.com statement is here.
It has been reported by Revision3.com that the DoS came from MediaDefender, a company that has been hired by the RIAA and MPAA in the past for the purpose of stopping filesharing. While they appear to be in violation of 18 USC 1030, it is unsure if charges will be brought against MediaDefender. Or, if it can be proven that the RIAA and/or MPAA requested the DoS attack, that charges will be brought against the RIAA/MPAA.
They are, I hope, filing criminal charges under the Computer Fraud and Abuse act, as well as filing a civil suit demanding damages.
