Rather, Tiversa claims that evidence suggests that at least some of the documents were obtained by WikiLeaks via its own searches on peer-to-peer networks.

Tiversa's claims were dismissed outright by Mark Stephens, WikiLeaks' attorney, who that they are "completely false in every regard."

Tiversa, whose clients include the FBI, helps organizations monitor P2P networks for leaked data.

Over the past few years, the company has served up several sensational examples of highly sensitive information accidentally posted on file-sharing networks.

In 2009, for example, that it had found U.S. Secret Service details on a safe house for the U.S. First Family, along with presidential motorcade routes, on a LimeWire file-sharing network. Earlier that same year, Tiversa disclosed that it had found classified floating on a P2P network.
