US Army counterintelligence staff assessed the online whistleblower site Wikileaks for possible countermeasures after it posted secret Department of Defense documents.
A counterintelligence analysis report prepared by Michael Horvath of the cyber counterintelligence assessments branch of the US Army Counterintelligence Center said, Wikileaks represented "a potential force protection, counterintelligence, operational security (OPSEC), and information security (INFOSEC) threat to the US Army."
It said websites such as Wikileaks.org used trust as a "centre of gravity" by protecting the anonymity and identity of the insiders, leakers, or whistleblowers.
"The identification, exposure, termination of employment, criminal prosecution, legal action against current or former insiders, leakers, or whistleblowers could potentially damage or destroy this center of gravity and deter others considering similar actions from using the Wikileaks.org website," it said.
Wikileaks spokesman Julian Assange said the document was dated 28 February 2008. Because Wikileaks continued to receive classified material he assumed that any countermeasures introduced by the US Army had been "ineffective".
Late last year Wikileaks shut down due to financing problems. An appeal for donations attracted more than €200,000 in a few months.
Wikileaks is presently helping the Icelandic parliament prepare legislation to guarantee that Iceland would protect free speech, including whistleblowers and their evidence. This would give Wikileaks a permanent home.
The move comes in the wake of Icelandic anger that the UK used anti-terrorist legislation to freeze Icelandic bank assets during the meltdown of the banking system in 2008.
In its first-ever referendum, Iceland recently voted to reject a plan to repay the British and Dutch governments, who had paid their citizens' the deposits they lost when Icelandic banks were liquidated.
