Attribution, Delayed Attribution and Covert Cyber-Attack: Under What Conditions Should the United States Publicly Acknowledge Responsibility for Cyber Operations? [open pdf - 458KB]
From the thesis abstract: "Self-attribution is a public declaration of responsibility for the conduct of an operation. It is distinguished from covert operations, where perpetrators provide no such acknowledgement and attempt to conceal their identities. Although self-attribution is always an option, this thesis examines legal and strategic reasons for a nation state to publically [sic] acknowledge its role in the conduct of a cyber-operation. The central result is that whereas neither international law nor national policy requires self-attribution, under certain strategic conditions it may be preferred."
