Retired General and former NSA chief Paul Nakasone has warned that water system controllers should not be connected to the internet, following suspected Iranian cyberattacks on water facilities across at least 12 US states. Speaking at DEF CON, he highlighted the enormous attack surface posed by around 50,000 underfunded and understaffed water municipalities, calling for higher cybersecurity standards and a collaborative defence approach. While neither the FBI nor the Trump administration has officially attributed the attacks to Iran, security researchers and Nakasone himself consider Iranian involvement highly likely given the country's history and demonstrated capability in targeting such infrastructure.
