Prof. Stuart Madnick speaks with CNBC reporter Trevor Laurence Jockims about cybersecurity attacks on American water systems. Madnick explains that while a population’s water has not been shut off due to a hack, but “we have demonstrated in our lab how operations, such as a water plant, could be shut down not just for hours or days, but for weeks. It is definitely technically possible,” Madnick explains.
