On 20 October 2017, an anonymous Reddit user hinted at the existence of the Paradise Papers. Later that month, the International Consortium of Investigative Journalists (ICIJ) approached the offshore law firm Appleby with allegations of wrongdoing. Appleby said that some of its data had been stolen in a cyberattack in the previous year and denied the ICIJ's allegations. After media outlets started reporting on the documents, the company said there was "no evidence of wrongdoing", and they "are a law firm which advises clients on legitimate and lawful ways to conduct their business", and they "do not tolerate illegal behaviour".
