Researchers Dissect Cyberattacks

University of Michigan researchers have analyzed cyberattacks and created a mathematical model that looks at their risks and optimal launch times. In a paper they wrote, they state that several nations are stockpiling zero-day exploits to use as cyberweapons when needed. Their research examined the best time to use these exploits based on when security experts might discover a vulnerability that precipitates an attack and develop patches for it. The model was devised, in part say researchers to instigate a dialogue about cyberwarfare, including reaching an agreement that certain targets, namely civilian or banking infrastructure, should be off limits. The researchers published their findings in the Proceedings of the National Academy of Sciences. (The Telegraph)(NBCNews)(Proceedings of the National Academy of Sciences)

Computer Model Predicts Group Conflict

Scientists from the University of Wisconsin-Madison’s Wisconsin Institutes for Discovery have created a computational model to determine individuals’ ability to predict conflict. The researchers examined how much information an individual must remember about previous conflicts to infer what may occur in future events, specifically, whether situation will lead to conflict and how to react. The researchers’ model required 1,000 bits to map the likelihood that a given hypothetical situation would lead to conflict. The researchers say their findings relate to conflict in many biological systems, particularly collective behaviors in groups such as neurons or bird flocks. They say their work also provides insight into how cognitive organisms understand their environments. Their statistical modeling and computational frameworks could also be useful in behavioral science, game theory, and machine learning. The researchers published their results in Proceedings of the National Academy of Sciences. (PhysOrg)(University of Wisconsin-Madison)(Proceedings of the National Academy of Sciences)
