The $52.6 billion “black budget” for fiscal 2013, obtained by The Washington Post from former intelligence contractor Edward Snowden, maps a bureaucratic and operational landscape that has never been subject to public scrutiny. Although the government has annually released its overall level of intelligence spending since 2007, it has not divulged how it uses those funds or how it performs against the goals set by the president and Congress.

•Spending by the CIA has surged past that of every other spy agency, with $14.7 billion in requested funding for 2013. The figure vastly exceeds outside estimates and is nearly 50 percent above that of the National Security Agency, which conducts eavesdropping operations and has long been considered the behemoth of the community.

•The CIA and NSA have launched aggressive new efforts to hack into foreign computer networks to steal information or sabotage enemy systems, embracing what the budget refers to as “offensive cyber operations.”
