Metrics for quantifying information leakage assume that an adversary's gain is the defender's loss. We demonstrate that this assumption does not always hold via a class of scenarios. We describe how to extend quantification to account for a defender with goals distinct from adversary failure. We implement the extension and experimentally explore the impact on the measured information leakage of the motivating scenario.
