Known as Vault 7, thousands of documents from the CIA detailed covert programs in which devices like smart TV's and smartphones could spy on people.

CIA director Mike Pompeo said, "It is time to call out WikiLeaks for what it really is, a non-state hostile intelligence service often abetted by state actors like Russia."

At the time of its initial publishing, WikiLeaks says the CIA documents it released are just the tip of the iceberg, claiming they've only released 1 percent of their trove on the organization.
