Immediate Actions WWS Facilities Can Take Now to Protect Against Malicious Cyber Activity
• Do not click on suspicious links.
• If you use RDP, secure and monitor it.
• Use strong passwords.
• Use multi-factor authentication.
Note: This advisory uses the MITRE Adversarial Tactics, Techniques, and Common Knowledge (ATT&CK®) framework, version 9. See the ATT&CK for Enterprise for all referenced threat actor tactics and techniques.
This joint advisory is the result of analytic efforts between the Federal Bureau of Investigation (FBI), the Cybersecurity and Infrastructure Agency (CISA), the Environmental Protection Agency (EPA), and the National Security Agency (NSA) to highlight ongoing malicious cyber activity—by both known and unknown actors—targeting the information technology (IT) and operational technology (OT) networks, systems, and devices of U.S. Water and Wastewater Systems (WWS) Sector facilities. This activity—which includes attempts to compromise system integrity via unauthorized access—threatens the ability of WWS facilities to provide clean, potable water to, and effectively manage the wastewater of, their communities. Note: although cyber threats across critical infrastructure sectors are increasing, this advisory does not intend to indicate greater targeting of the WWS Sector versus others.
To secure WWS facilities—including Department of Defense (DoD) water treatment facilities in the United States and abroad—against the TTPs listed below, CISA, FBI, EPA, and NSA strongly urge organizations to implement the measures described in the Recommended Mitigations section of this advisory.

WWS facilities may be vulnerable to the following common tactics, techniques, and procedures (TTPs) used by threat actors to compromise IT and OT networks, systems, and devices.
Cyber intrusions targeting U.S. WWS facilities highlight vulnerabilities associated with the following threats:
WWS Sector cyber intrusions from 2019 to early 2021 include:
The FBI, CISA, EPA, and NSA recommend WWS facilities—including DoD water treatment facilities in the United States and abroad—use a risk-informed analysis to determine the applicability of a range of technical and non-technical mitigations to prevent, detect, and respond to cyber threats.
Personnel responsible for monitoring WWS should check for the following suspicious activities and indicators, which may be indicative of threat actor activity:
Note: The increased use of remote operations due to the COVID-19 pandemic increases the necessity for asset owner-operators to assess the risk associated with enhanced remote access to ensure it falls within acceptable levels.
FBI, CISA, EPA, and NSA would like to thank Dragos as well as the WaterISAC for their contributions to this advisory.
CISA offers a range of no-cost cyber hygiene services—including vulnerability scanning and ransomware readiness assessments—to help critical infrastructure organizations assess, identify, and reduce their exposure to cyber threats. By taking advantage of these services, organizations of any size will receive recommendations on ways to reduce their risk and mitigate attack vectors.
The U.S. Department of State’s Rewards for Justice (RFJ) program offers a reward of up to $10 million for reports of foreign government malicious activity against U.S. critical infrastructure. See the RFJ website for more information and how to report information securely.
The StopRansomware.gov webpage is an interagency resource that provides guidance on ransomware protection, detection, and response. This includes ransomware alerts, reports, and resources from CISA and other federal partners, including:
