A new mathematical model identifies the precise, most vulnerable moment for hackers to attack a cyber victim to inflict the most damage. Where are these scientists at exactly? The University of Michigan. However, they are not trying to enable hackers but predict their next attack. They say using their model makes it possible to calculate the optimum time of a cyber-attack. They tested their model based on the Stuxnet attack of Iran’s nuclear program and other highly organized attacks that exhibited optimal timing. It may be developed for cyber-attacks but it can be equally effective in modeling cyber-defense.
