Operations Support Branch

The Operations Support Branch (OSB) is a unit of the cyber-intelligence division of the Central Intelligence Agency (CIA). It is located on the ninth floor of a secret facility in the suburbs of northern Virginia, west of Washington, D.C. Patrick Radden Keefe described the OSB as the CIA's "secret hacker unit, in which a cadre of élite engineers create cyberweapons" in a June 2022 article for The New Yorker.
