Radical transparency site WikiLeaks has gone after author Michael Wolff following the publication of a controversial book that puts the Trump White House in an unflattering light.
The Twitter account for the organisation published the link to the book by the New York-based media critic which has created a firestorm for US President Donald Trump over the past week.
"New Trump book 'Fire and Fury' by Michael Wolff. Full PDF:" were the only words in the tweet, followed by what appears to be a link to a Google Drive file.
The PDF file contains no page numbers, and it is not clear if it is the final version of the book.
Such moves to undermine the financial viability of the highly anticipated book echo the North Koreans' hacking of Sony Pictures in 2014, when vast amounts of the company's intellectual property was posted online in an act of aggression.
WikiLeaks' intervention comes after Fire and Fury ignited fresh concern over the mentality stability of Trump and his fitness for office.
Former White House senior adviser Stephen Bannon was quoted in the book calling Donald Trump jnr's meeting with Russians "treasonous" - words he has since walked back in US media.
In 2016 WikiLeaks waded into the US election by publishing emails from key figures in Hillary Clinton's campaign and the Democratic Party. The emails were assessed to have been stolen by Russia-based hacking outfits.
WikiLeaks head Julian Assange has denied acting as a front for Russian influence efforts.
WikiLeaks recently lost a significant source of funding when the Freedom of the Press Foundation decided to stop processing donations from its readers.
The US-based organisation, which describes itself as protecting and defending "adversarial journalism in the 21st century", helped WikiLeaks circumvent an unofficial financial blockade by major payment processing companies, dating back to about 2011.
In December, the foundation said it could no longer find evidence of a financial blockade against WikiLeaks and so would no longer process payments for the organisation.
The group reportedly helped facilitate $US500,000 ($636,000) in individual donations to WikiLeaks over five years.
Part of the foundation's change of heart was due to WikiLeaks' role in the 2016 US election, which comes amid Assange's seeming embrace of Trump and white nationalists in his twitter feed, the Daily Beast reported.
The Freedom of the Press Foundation counts among its members Pentagon Papers whistleblower Daniel Ellsberg, former US National Security Agency contractor Edward Snowden - currently living in Russia - and Glenn Greenwald, co-founder of the US media organisation The Intercept.
