A hacker gained access to the Oldsmar’s water treatment plant, bumping the sodium hydroxide in the water to a “dangerous” level, according to Pinellas County’s sheriff.
In a press conference Monday, Sheriff Bob Gualtieri said his deputies, along with the FBI and U.S. Secret Service, are investigating the breach as it is unclear if it came from within the U.S. or from a foreign actor.
The incident first occurred on Feb. 5 at the city’s water treatment plant when, around 8 a.m., an operator noticed someone had remotely entered the computer system that he was monitoring. It’s a system responsible for controlling the chemicals and other operations of the water treatment plant, Gualtieri said.
