STONEGHOST or "Stone Ghost", is a codename for a network operated by the United States' Defense Intelligence Agency (DIA) for information sharing and exchange between the United States, the United Kingdom, Canada and Australia.[1] Some sources say that New Zealand is also participating, and that Stone Ghost therefore connects, and is maintained by the defense intelligence agencies of all Five Eyes countries.[2][3]

Stone Ghost does not carry Intelink-Top Secret information. In the past, it was known as Intelink-C and may also be referred to as "Q-Lat" or "Quad link".[1] It is a highly secured network with strict physical and digital security requirements. The network hosts information about military topics, and about SIGINT, foreign intelligence and national security.[2][3]

2012 Canadian spy case

Royal Canadian Navy intelligence officer Sub-Lt. Jeffrey Delisle pled guilty on 10 October 2012 to charges including having downloaded and sold information from the Stone Ghost system to the Russian spy agency GRU.[4][5] He was sentenced to 20 years in prison, minus time served on February 6, 2013, for contravening the Security of Information Act.[6][7]
