Attribution and Secrecy in Cyberspace

| March 8, 2016

"A key component of our framework entails distinguishing between two qualitatively different types of secrecy in the cyber domain. The first — the use of secrecy at the planning and execution stages of an attack — is often a technical prerequisite for success. The second type of secrecy — whether to claim credit for an attack privately or publicly — is a political decision. While many factors plausibly drive credit-claiming or credit-shirking behavior, two in particular stand out as significant: (1) whether target compliance is the objective; and (2) whether the perpetrator is a state or a non-state actor."
