CNN - Mike Theis, Rapid City’s public works director.

CNN - New York Governor Kathy Hochul.

CNN - Democratic Senator Adam Schiff of California.

WHAT:

CNN - The cyber intrusions led to water pressure drops and flooding at facilities, but did not compromise the safety of drinking water, according to the FBI.

CNN - The Clayton County Water Authority accomplished restoring the system in a matter of hours on July 27.

CNN - New York Governor Kathy Hochul announced about $9 million in grants to strengthen cyber defenses of water systems across New York.

CNN - Senator Schiff plans to introduce legislation next week that would give the Environmental Protection Agency greater authorities to help boost water cyber defenses.

CNN - The cyber intrusions led to water pressure drops and flooding at facilities, but did not compromise the safety of drinking water.

CBS News - The nation's 152,000 public water systems often lack defenses against malicious actors, according to cybersecurity experts.

CNN - A cyberattack affected water systems in a dozen states, leading to water pressure drops and flooding at facilities.

CNN - The FBI reported that the cyber intrusions did not compromise the safety of drinking water.

CNN - The Clayton County Water Authority experienced a water pump station failure due to "unauthorized cyber activity," triggering a boil-water notice on July 27.

CNN - A "cyber incident" hit a lift station serving Rapid City's wastewater system, announced on July 31.

CNN - New York Governor Hochul announced about $9 million in grants to strengthen cyber defenses of water systems across New York.

CNN - Senator Schiff plans to introduce legislation to give the Environmental Protection Agency greater authorities to boost water cyber defenses.

WHERE:

CNN - Water systems affected include locations from South Dakota to Georgia.

CNN - Clayton County, Georgia.

CNN - Rapid City, South Dakota.

WHEN:

WHY:

CNN - Experts have warned that the soft underbelly of American infrastructure, including local water and power plants, has been targeted by adversaries like Russia, China, and Iran.

CNN - Experts warn that US water systems are vulnerable due to years of under-investment and lack of resources.

CNN - Adversaries like Iran, Russia, and China are suspected of developing access to sensitive industrial networks in the US.

CNN - Targeting critical infrastructure can undermine public confidence in leaders and impose significant costs with relatively little effort.

HOW:

NBC News - Vanderbilt University researchers are working to create “digital twins” of water system networks as part of a new initiative to enhance cybersecurity.

CNN - Cyber intrusions exploited vulnerabilities in water systems that are directly accessible from the internet.

CNN - Rapid City officials credited quick action from employees who noticed abnormal behavior on computer systems and isolated them from the internet.

Cyber intrusions have caused water pressure drops and flooding at facilities, but the FBI assures that the safety of drinking water remains uncompromised. In response to these threats, New York Governor Kathy Hochul has announced approximately $9 million in grants to bolster the cyber defenses of water systems across the state, while Senator Schiff is set to introduce legislation next week aimed at empowering the Environmental Protection Agency to enhance water cyber protections. Meanwhile, researchers at Vanderbilt University are developing "digital twins" of water system networks as part of a new initiative to improve cybersecurity in this critical infrastructure.

Cyber intrusions have caused water pressure drops and flooding at facilities across the nation, although the safety of drinking water remains uncompromised. Experts highlight that the 152,000 public water systems in the U.S. often lack adequate defenses against malicious actors, with adversaries like Russia, China, and Iran targeting this vulnerable infrastructure. In response, researchers at Vanderbilt University are developing “digital twins” of water system networks to bolster cybersecurity and protect these critical resources.

(UPDATED August 7, 2026 03:54 UTC)

A significant cyberattack has impacted water systems across a dozen states, causing water pressure drops and flooding at various facilities, although the FBI has confirmed that drinking water safety remains uncompromised. In response to these incidents, New York Governor Kathy Hochul announced approximately $9 million in grants to enhance the cyber defenses of water systems, while Senator Adam Schiff plans to introduce legislation next week aimed at empowering the Environmental Protection Agency to bolster these defenses. The cyber intrusions, which exploited vulnerabilities in systems accessible from the internet, have raised alarms among experts who warn that years of under-investment have left U.S. water infrastructure particularly vulnerable to adversaries like Iran, Russia, and China.
