Cybersecurity needs to be top priority in nation’s water utilities

In February 2021, with a few clicks of a mouse, a hacker remotely adjusted the chemicals at a water treatment system in Oldsmar, Fla. Had the change not been detected, it would have turned the community’s water into poison.

That cyberattack came on the heels of another hacker breaching the drinking water system that serves parts of the San Francisco Bay area. In that cyberattack, programs used to treat water were deleted. The hack went unnoticed until the following day.
