In March 2008, the Department of Defense supposedly published a memo about a perceived national security threat. The target: Wikileaks a site that had previously put out sensitive information about Abu Ghraib.
It's been two years since that memo, which Wikileaks has published (PDF), and there's no clear evidence that Wikileaks was ever tampered with. But it's chilling to think that it could have ever even—and still may be—a possibility. Sites like Wikileaks catalog our secret history, the version that we weren't supposed to know. In fact, according to the memo, the DoD's primary concern was that someone from inside the government was feeding the site important documents:
The possibility that a current employee or mole within DoD or elsewhere in the U.S. government is providing sensitive information or classified information to Wikileaks.org cannot be ruled out. Wikileaks.org claims that the "leakers" or "whistleblowers" of sensitive or classified DoD documents are former U.S. government employees. These claims are highly suspect, however, since Wikileaks.org states that the anonymity and protection of the leakers or whistleblowers is one of its primary goals.
In other words, a primary source.
According to the memo, the DoD considered Wikileaks' weaknesses, at least in regards to finding those moles through site exploits:
The obscurification technology used by Wikileaks.org has exploitable vulnerabilities. Organizations with properly trained cyber technicians, the proper equipment, and the proper technical software could most likely conduct computer network exploitation (CNE) operations or use cyber tradecraft to obtain access to Wikileaks.org's Web site, information systems, or networks that may assist in identifying those persons supplying the data and the means by which they transmitted the data to Wikileaks.org. ...
Successful identification, prosecution, termination of employment, and exposure of persons leaking the information by the governments and businesses affected by information posted to Wikileaks.org would damage and potentially destroy [its] center of gravity and deter others from taking similar actions.
A frightening thought, although to date there haven't been any reports of Wikileak source exposures. (Though they've definitely screwed up themselves.)
