While the United States is trying to hunt for the individual behind the massive leak of US military data on Afghanistan war, the whistleblowers’ website, that made the 91,000 classified documents available to the world, has said that the source of leak is unknown.
The layer of secrecy helps protect the site’s sources from spy agencies and hostile corporations, the Australian hacker said.
He, however, acknowledged that the site’s anonymous submissions have raised concerns about the authenticity of the material.
Assange claimed that WikiLeaks has not yet encountered any such bogus material.
