Operation Payback is a coordinated, decentralized group of attacks on opponents of Internet piracy by Internet activists using the "Anonymous" moniker - a group sometimes affiliated with the website 4chan. Operation Payback started as retaliation to distributed denial of service (DDoS) attacks on torrent sites; piracy proponents then decided to launch DDoS attacks on piracy opponents. The initial reaction snowballed into a wave of attacks on major pro-copyright and anti-piracy organizations, law firms, and individuals. Following the United States diplomatic cables leak in December 2010, the organizers commenced DDoS attacks on websites of banks who had withdrawn banking facilities from WikiLeaks.

In 2010, several Bollywood companies hired Aiplex Software to launch DDoS attacks on websites that did not respond to takedown notices. Piracy activists then created Operation Payback in September 2010 in retaliation. 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 Motion Picture Association of America (MPAA) and International Federation of the Phonographic Industry, giving the two websites a combined total downtime of 30 hours. In the following two days, Operation Payback attacked a multitude of sites affiliated with the MPAA, the Recording Industry Association of America (RIAA), and British Phonographic Industry. Law firms such as ACS:Law, Davenport Lyons and Dunlap, Grubb & Weaver (of the US Copyright Group) were also attacked.

Gene Simmons (born Chaim Weitz Hebrew: חיים ויץ‎; August 25, 1949) is an Israeli-American rock bassist, singer-songwriter, entrepreneur and actor. Known as "The Demon", he is the bassist/co-vocalist of Kiss, a hard rock band he co-founded in the early 1970s. Kiss has sold over 100 million albums worldwide.

Chaim Weitz (later Gene Simmons) was born at the Rambam Hospital in Haifa, Israel in 1949. Mother and child emigrated to Jackson Heights, Queens in New York City when he was eight years old. His mother Flóra "Florence" Klein (formerly Kovács) was born in Jánd, Hungary. The German name Klein (means: small) is sometimes used informally in Hungarian as Kis, this however, did not give the band its name. Florence and her brother, Larry Klein, were the only members of the family to survive the Holocaust. Simmons' father, Feri Witz, also Hungarian-born, remained in Israel, where he had one other son and three daughters. Simmons says the family was "dirt poor," scraping by on bread and milk. In the United States, Simmons changed his name to Eugene Klein (later Gene Klein), adopting his mother's maiden name. He was a part of Yeshiva Torah Vodaath in Williamsburg, Brooklyn as a child, from 7 am to 9:30 pm
