Ongoing Cyber Threats to U.S. Water and Wastewater Systems Sector Facilities

CISA, the Federal Bureau of Investigation (FBI), the Environmental Protection Agency (EPA), and the National Security Agency (NSA) have released a joint Cybersecurity Advisory (CSA) that details ongoing cyber threats to U.S. Water and Wastewater Systems (WWS) Sector. This activity—which includes cyber intrusions leading to ransomware attacks—threatens the ability of WWS facilities to provide clean, potable water to, and effectively manage the wastewater of, their communities. The joint CSA provides extensive mitigations and resources to assist WWS Sector facilities in strengthening operational resilience and cybersecurity practices.

CISA has also released a Cyber Risks & Resources for the Water and Wastewater Systems Sector infographic that details both information technology and operational technology risks the WWS Sector faces and provides select resources.
