Cyberattacks Hit US Water Systems in 7 States; Iran Probed

Federal investigators are examining whether Iranian state-backed hackers were behind cyberattacks that struck water systems in at least seven US states. The attacks forced some facilities to issue boil-water notices or switch to manual operations, but officials say there is no evidence drinking water was contaminated. Iran is the leading suspect, though no definitive proof has been established. President Donald Trump rejected the Iran link, saying he doesn't think there was an Iranian cyberattack.
