Megaupload Ltd was a Hong Kong-based online company established in 2005 that operated from 2005 to 2012 providing online services related to file storage and viewing.On 19 January 2012, the United States Department of Justice seized the domain names and closed down the sites associated with Megaupload after the owners were arrested and indicted for allegedly operating as an organization dedicated to copyright infringement. Subsequently, HK$330 million (approximately US$42 million) worth of assets were frozen by the Customs and Excise Department of Hong Kong. The company's founder, New Zealand resident Kim Dotcom, has denied any wrongdoing, and the case against Dotcom has been the subject of controversy over its legality. In 2017, a New Zealand judge ruled that Dotcom should be extradited to the United States, but Dotcom remained at liberty in New Zealand pending the results of an appeal. On 5 July 2018 the New Zealand court of appeal found Dotcom and three of his former colleagues were eligible to be extradited to the U.S. authorities. His lawyer said they would appeal to the New Zealand Supreme Court. The shutdown of Megaupload led to denial-of-service (DoS) attacks on a range of websites belonging to the U.S. government and copyright organizations by the Hacktivist group Anonymous.On 19 January 2013 (2013-01-19), Megaupload was re-launched as Mega under the domain name mega.co.nz (later moved to mega.nz, and then to mega.io). The re-launch date was chosen to coincide with the one-year anniversary of Megaupload's takedown by the U.S. Federal Bureau of Investigation.
