The vendor is located in the United States, and Weiss worries about what other systems are at risk. "One thing that is important to find out is whose SCADA system this is," he said. "If this is a [big software vendor], this could be so ugly, because a biggie would have not only systems in water utilities but a biggie could even be [used] in nukes." Weiss discussed the breach yesterday on his blog, calling for better coordination and disclosure from government organizations. Because of this lack of coordination and disclosure, Weiss wrote, other water utilities were not aware of the breach, and their own vulnerability to cyber attacks. It may not be one of the biggest data thefts in history, but it's certainly one of the more odd.
