Hackers break into water treatment facility computers, try to poison Florida by changing chemical levels

A major mishap was averted after a hack that was made into the computer system of a water treatment facility was averted. The hackers attempted to add a dangerous level of additive to the water supply that would have led to the poisoning of nearly 15,000 people near Tampa, Florida who get water from the facility. "This is obviously a significant and potentially dangerous increase," Pinellas County Sheriff Bob Gualtieri said.
