"A computer hacker gained access to the water system of a city in Florida and tried to pump in a "dangerous" amount of a chemical, officials say.

The hacker briefly increased the amount of sodium hydroxide (lye) in Oldsmar's water treatment system, but a worker spotted it and reversed the action.

In 2016, a security report from Verizon detailed a similar attack on another unnamed US water facility. And in 2020 there were multiple unsuccessful hacks on Israeli water supplies."

So if you couple electricity off with poisoning the water supply - that's gonna have a crippling impact.

This raises the question again - at what point is a cyber war a real war?

If someone is shooting at you it's easy to know - and respond - but where's the line in a cyber war?
