This paper introduces branching processes as a stochastic tool for understanding the characteristics of the abuse of leaked information, and the associated risks. To understand the risk associated with information leakage, it is important to produce models capturing important aspects of the abuse of leaked information. This understanding is necessary to limit such risks effectively and efficiently. Filling part of an apparent gap in this area, a stochastic model based on a discrete-time branching process is introduced. Some gen eral challenges associated with modelling information leak risks are identified, as well as some challenges associated with using branching processes to analyze operational risk.
