Some of the world's richest people are preparing to have their financial details exposed after hackers compromised the computer systems of offshore giant Appleby.
Hackers, who penetrated the Bermuda-based company last year and compromised data it held on clients, have passed the information to journalists, according to The Daily Telegraph.
The paper reported that Britain's wealthiest people are instructing law firms and public relations experts to prepare to protect their reputations.
It said that "a global consortium of Left-leaning media organisations is preparing to release the information in the coming days".
The release comes a year after the hidden wealth of some of the world's most prominent figures, politicians and celebrities was revealed in the Panama Papers leak.
The Panama Papers resulted in lasting damage for a number of the figures named, including Iceland's Prime Minister, who stepped down after suggestions he held investments in Iceland's collapsed banks.
Appleby describes itself as "an offshore law firm who advises clients on legitimate and lawful ways to conduct their business".
"We do not tolerate illegal behaviour. It is true that we are not infallible. Where we find that mistakes have happened we act quickly to put things right and we make the necessary notifications to the relevant authorities," the company stated.
Appleby said that it is "disappointed that the media may choose to use information which could have emanated from material obtained illegally and that this may result in exposing innocent parties to data protection breaches."
It added that after looking into unspecified allegations made against it, it believes "they are unfounded and based on a lack of understanding of the legitimate and lawful structures used in the offshore sector."
