The leaks are expected to be published in the near future by a news outlet that was not further identified by the officials familiar with details of the compromise. The NSA is aware of the news outlet’s forthcoming disclosures and is taking steps to try and minimize any damage they will cause.
According to the officials, the latest NSA disclosure of secrets is not the result of an insider stealing documents, as occurred in the case of fugitive NSA contractor Edward Snowden.
Instead, the leaks will reveal certain NSA technical cyber intelligence gathering capabilities. The officials did not provide details about the leaks.
