Did Iran hack water systems in seven US states?

What the report says

BBC World News reports that US authorities are investigating a wave of cyber incidents affecting water systems in multiple states, after Minnesota said more than 30 of its water systems were hit by a coordinated attack. The FBI later said it had received reports of cyber-attacks in seven states and that some activity had disrupted water operations. The Cybersecurity and Infrastructure Security Agency, or CISA, is also said to be examining whether there is any Iranian link, although it has not publicly commented on the matter.

The BBC says US President Donald Trump has not blamed Iran and has instead criticized Minnesota officials. Cybersecurity experts interviewed by the BBC said the pattern and timing make Iran a plausible suspect, while also noting that attribution in cyber cases can be difficult and that attackers may try to disguise their origin. Iran has not commented on the latest claims, and the report notes that Tehran has denied involvement in previous cyber incidents.

The article places the current case in the context of earlier attacks on US and Israeli targets that US agencies and investigators have linked to Iran or Iran-aligned groups. Experts told the BBC that the most immediate risk may be to public trust in utilities rather than a major water-supply failure, though they warned that older infrastructure and weak security leave water systems vulnerable. The report says CISA and the Environmental Protection Agency have urged utilities to strengthen protections, including removing exposed systems from the internet and resetting passwords.
