In 1986, astronomer turned computer scientist Clifford Stoll had just started working on a computer system at the Lawrence Berkeley Laboratory when he noticed a 75-cent discrepancy between the charges printed by two accounting programs responsible for charging people for machine use.

This is the re-enactment of how he tracked down KGB cracker Markus Hess through the Ethernet to Hannover, Germany.
