CISA Warns Water Utilities: Find Your Exposed PLCs Before Attackers Do
CISA urged water utilities to secure internet-exposed PLCs after July 2026 attacks compromised over 100 US water and wastewater systems, suspected Iran-linked.
CISA's exposure-reduction guidance, published August 21, follows July 2026 attacks in which threat actors remotely accessed PLCs connected directly through cellular modems, changed device IP addresses and passwords, and in some cases disabled alarms and shutdown processes without notifying operators. Iran is the suspected actor, though officials stopped short of formal attribution. CISA recommends routing remote access through centrally managed secure gateways, phishing-resistant MFA, unique credentials, and external scanning of industrial protocols such as Modbus, EtherNet/IP, DNP3, BACnet and OPC UA.
OpenAI Announced $1B in Defensive Tools for Water Utilities
OpenAI pledges $1 billion in subsidized Daybreak cyber models and training for water utilities, grid operators, and other critical-infrastructure defenders.
OpenAI announced Daybreak for Frontline Defenders on September 3, 2026, committing $1 billion in product credits and subsidized access to its Daybreak cyber models, training, and technical support for under-resourced defenders. Priority access goes to water and wastewater utilities, electric grid operators, state and local governments, community banks, nonprofits, and open-source maintainers; around 2,000 organizations already use Daybreak, which includes Daybreak Blue and Daybreak Red tiers. The program includes an MS-ISAC pilot, the Daybreak Defense Network with 35+ partner products (including HackerOne), and publication of OpenAI's Defense Factory automated vulnerability discovery architecture; it launched the same day OpenAI shipped a model it internally classifies as Critical for cyber capability.
