National reports suggest water systems in at least a dozen states have been in the crosshairs of hackers, with officials pointing to Iran as a likely culprit.
Beshear was asked Thursday if Kentucky was on the list.
"To my knowledge, the answer is no. We are not one of those 12 states that have had their water systems hacked," he said.
Yet the governor was cautious, saying he would need to double-check on the latest information available to his office.
And even if Kentucky hasn't been targeted yet, he warned countries ranging from Iran to Russia to China are actively "working every day, through buildings full of hackers, to try to harm us in all different types of ways. And I hope this is a wake up call about how damaging it could be."
Cyber security experts tell CBS News the incidents reveal longstanding gaps in thousands of public water systems, many of which run on poorly-secured, internet-connected industrial computers.
Michael Garcia, policy director with the Operational Technology Cybersecurity Coalition, described the utility systems as "low-hanging fruit" for hackers.
