  • WaterISAC flags exposed OT, PLCs and integrators as water sector threats mount
    WaterISAC says internet-exposed OT and PLCs remain the water sector's biggest weaknesses as cyberattacks mounted this summer, and announced a threat-sharing partnership with Cyware.

    • Applies to U.S. water and wastewater utilities, especially the smallest systems served via WaterISAC's partnership with the National Rural Water Association covering 20,000 utilities.
    • Most vulnerable: internet-exposed operational technology and aging programmable logic controllers, which were the main point of entry in this summer's attacks and were designed before cyber threats existed.
    • Other attack paths: unmanaged connections through outside integrators and phishing of employees; smaller utilities struggle with basics like password changes and MFA.
    • Threats come from Iran โ€” reportedly behind this summer's water facility attacks per CISA, though President Trump has disputed that โ€” as well as China and Russia.
    • WaterISAC is partnering with Cyware's threat intelligence platform to speed up threat sharing and enable cross-sector sharing with other ISACs.
