CISA has warned of a significant rise in cyberattacks targeting US water systems, with over 100 internet-exposed programmable logic controllers attacked in July 2026 alone. The attacks caused password lockouts, IP changes, boil water notices, and forced manual operations across facilities in at least 12 states. Attribution remains unconfirmed, though an Iranian state-sponsored group is suspected. CISA urges operators to remove PLCs from public internet access immediately.
