Whistleblowing website Wikileaks has begun publishing the first of more than five million confidential emails from US-based intelligence company Stratfor.
The group said the documents would reveal Stratfor's "web of informers, pay-off structure, payment-laundering techniques and psychological methods".Stratfor's computers were hacked by the activist group Anonymous in December.
Stratfor boss George Friedman said at the time anyone looking for signs of a vast conspiracy would be disappointed.
The firm warned ahead of the Wikileaks publication that it would make no comment on whether any of the emails were authentic or inaccurate.
"Having had our property stolen, we will not be victimised twice by submitting to questioning about them," Stratfor said in a statement.
'Shadow CIA'
Wikileaks did not say how it acquired the documents, but it is widely assumed to have been given them by the loose-knit hacker group Anonymous, which claimed to have stolen emails, passwords and credit-card details from the Texas-based firm in December.
Wikileaks said the emails date from July 2004 to the end of last year.
The first set of emails include messages suggesting US firm Dow Chemical had Stratfor monitor groups that campaigned for victims of the 1984 Bhopal gas tragedy in India.
Also in the files are emails involving a request by Coca-Cola for Stratfor to investigate animal rights group Peta ahead of the 2010 Vancouver Olympics, amid concerns by the drinks-maker that it could face protests by Peta activists.
