Hackers could use connected cars to gridlock whole cities

EurekAlert  July 28, 2019 A team of researchers in the US (Georgia Institute of Technology, industry) studied a scenario envisioned by cybersecurity experts leading to a large number of internet-connected vehicles being suddenly and simultaneously disabled. To investigate the aftermath of the post hack they used an agent-based simulation and discovered the critical relevance of percolation for probabilistically predicting the outcomes on a multilane road in the immediate aftermath of a vehicle-targeted cyberattack. They developed an analytic percolation-based model to rapidly assess road conditions given the density of disabled vehicles and applied it to study the street network of Manhattan […]
