Embattled document-sharing site says the trove of documents “reveal the inner workings” of Strategic Forecasting, which suffered a hack late last year.

WikiLeaks announced today it would begin publishing on Monday more than 5 million confidential e-mails obtained from an influential security think tank.

The e-mails, which date from July 2004 to December 2011, “reveal the inner workings” of Strategic Forecasting (Strafor), an Austin, Texas-based firm that provides security analysis to the U.S. Army, Lockheed Martin, and Northrop Grumman, the embattled document-sharing site said in a statement.

“The emails show Stratfor’s web of informers, pay-off structure, payment-laundering techniques, and psychological methods,” the organization said.

The trove also purportedly contains more than 4,000 e-mails mentioning WikiLeaks or its founder, Julian Assange.

“Here we have a private intelligence firm, relying on informants from the US government, foreign intelligence agencies with questionable reputations, and journalists,” Assange told Reuters. “What is of grave concern is that the targets of this scrutiny are, among others, activist organizations fighting for a just cause.”
