Authorities in Florida said investigations were underway after a hacker attempted to poison the water supply to the city of Oldsmar on February 5. Pinellas County Sheriff Bob Gualtieri held a press conference on February 8 in which he said a hacker briefly increased the amount of sodium hydroxide, also known as lye, to “dangerous” levels after remotely accessing a computer for the city’s water treatment system.

Mayor Eric Seidel said the monitoring protocols in place would have caught the change in the water’s pH level if the supervisor had not observed it.
