Suspected hacks on US water systems spread to at least 7 states
What's new: Officials increasingly suspect Iran, though investigators say forensic proof is still preliminary and no water has been deemed unsafe.
Cyberattacks targeting US water systems have expanded to at least seven states, raising alarms over the security of critical infrastructure as investigators increasingly focus on Iran. Minnesota first disclosed the activity, and Michigan later said its systems had also been targeted. Officials and experts said there is no indication any drinking water was altered or made unsafe, but utilities remain on alert over vulnerable industrial-control computers used to manage chemical treatment and water pressure. President Donald Trump cast doubt on Iran's role and blamed Minnesota, while Gov. Tim Walz rejected that claim. Federal officials privately still view Iran as the leading suspect, though they say the inquiry remains in its early stages and may take months to reach firm conclusions.
