In an interview on Wednesday with security company PandaLabs, which has been in contact with Anonymous since the attacks and counter-attacks began, an organiser of the group said Anonymous had a mission to "fight back against the anti-piracy lobby". The organiser said that the collective had been provoked by the UK Digital Economy Bill and "three-strikes legislation in the EU" -- a possible reference to France's Hadopi laws or MEPs' recent backing of a copyright crackdown document. The organiser added that their attacks would "keep going until we stop being angry".
The attacks by Anonymous, which describes itself as non-hierarchical anarchy, began after an Indian security firm called AiPlex Software assaulted the servers of file-sharing sites such as The Pirate Bay with distributed denial-of-service (DDoS) assaults. Anonymous responded with its own DDoS attacks in a campaign called 'Operation Payback', first targeting the websites of US rights holder groups the Motion Picture Association of America (MPAA) and the Recording Industry Association of America (RIAA), then turning to smaller companies such as AiPlex and UK law firms who act on behalf of rights holders.
