Investigators are probing whether Iranian hackers are behind the malicious cyber activity this week that targeted water systems in seven states, including Minnesota. If they are found to be the culprits, it would not be the first time Iranian actors have been linked to cyberattacks against the U.S. For more than a decade, Iranian-linked operators have repeatedly hacked accessible American targets. They scan for widespread vulnerabilities and aim to create disruption, intimidate, gain publicity and undermine trust in the American government. But official confirmation can take weeks or months as investigators collect technical evidence. Investigators are also looking into whether the actor could have attempted to appear Iran-based as a way of stirring the pot amid the U.S. war with Iran. How will USA react when it is already at war with Iran?
