Operation CHAOS or Operation MHCHAOS was the code name for a domestic espionage project conducted by the Central Intelligence Agency. A department within the CIA was established in 1967 on orders from President of the United States Lyndon B. Johnson and later expanded under President Richard Nixon.

The operation was launched under Director of Central Intelligence (DCI) Richard Helms, by chief of counter-intelligence, James Jesus Angleton, and headed by Richard Ober. The program’s goal was to unmask possible foreign influences on the student antiwar movement.

Below, you will find the documents collected under the Freedom of Information Act (FOIA), which includes records on not only Operation CHAOS, but also these related programs:

Project MERRIMAC – Designed to infiltrate domestic antiwar and radical organizations thought to pose a threat to security of CIA property and personnel.

Project RESISTANCE – Worked with college administrators, campus security and local police to identify anti-war activists and political dissidents without any infiltration taking place

Kryptos is an encrypted sculpture by American artist Jim Sanborn located on the grounds of the Central Intelligence Agency (CIA) in Langley, Virginia. Since its dedication on November 3, 1990, there has been much speculation about the meaning of the encrypted messages it bears. Of the four messages, three have been solved, with the fourth remaining one of the most famous unsolved codes in the world. The sculpture continues to provide a diversion for cryptanalysts, both amateur and professional, who are attempting to decrypt the final section.

The below represents multiple FOIA requests to get documents on the sculpture declassified.

The National Security Agency (NSA) Documents

In the early 1990s, the NSA proposed a challenged that was taken up by a small group of cryptanalysts who wanted to decode the message on the Kryptos statue.  The documents below were the results of their research, including clues to deciphering the still unencrypted ‘fourth message.’

 The CIA Kryptos Sculpture [ 98 Pages, 2.36MB ] – This document was declassified and released to The Black Vault in September of 2014.  It took nearly 3 years to process.

 NSA Documents on Kryptos [ 60 Pages, 8.56MB ] – This was the first batch of documents released to The Black Vault by the NSA, in relation to my 2011 FOIA request.

 CIA Released Document, 9 July 2014 [ 2 Pages, 8.56MB ] – This single document was referred by the NSA to the CIA for review and release.
