In 2010, several Bollywood companies hired Aiplex Software to launch DDoS attacks on websites that did not respond to software takedown notices. Piracy activists then created Operation Payback in September 2010 in retaliation.[74] The original plan was to attack Aiplex Software directly, but upon finding some hours before the planned DDoS that another individual had taken down the firm's website on their own, Operation Payback moved to launching attacks against the websites of copyright stringent organisations, Law firms and other websites. This grew into multiple DDoS attacks against anti-piracy groups and law firms. On December 2010 Operation Payback organizers focused their attention in DDoS websites of companies that oppose WikiLeaks.
