Ethical Hacking News
Foreign hackers have targeted two small private water utilities in Colorado, changing equipment settings, disabling remote access and alarms, and modifying pumping cycles. The attacks, which were brief and did not affect water services or public safety, highlight the growing concern for the cybersecurity of the nation's water infrastructure.
Foreign hackers have been targeting small private water utilities in the US, attempting to disrupt operations and pose a threat to national security. The affected utilities often have limited resources and expertise, leaving them vulnerable to attack. CISA has warned that directly connecting programmable logic controllers (PLCs) to the internet through cellular modems can create significant security risks. Over 100 internet-exposed systems in the US water and wastewater sector were compromised in July 2022, highlighting the need for improved cybersecurity. The US government must take action to strengthen the cybersecurity of critical infrastructure, providing necessary resources and support to prevent foreign threats.
In recent months, a series of cyberattacks has targeted small private water utilities in the United States, highlighting the growing concern for the cybersecurity of the nation's water infrastructure. According to a report by the Cybersecurity and Infrastructure Security Agency (CISA), foreign hackers have been attempting to disrupt the operations of these small utilities, changing equipment settings, disabling remote access and alarms, and modifying pumping cycles. The attacks, which were carried out in late August, were brief and did not affect water services or public safety, but they do pose a significant threat to the country's national security.
The affected utilities, which serve fewer than 200 people, are often small and rural, and may not have the resources or expertise to implement robust cybersecurity measures. This vulnerability is particularly concerning, as it leaves these critical infrastructure systems open to attack by foreign actors who may seek to disrupt the supply of clean water to communities.
The attacks are believed to be part of a larger campaign by an Iranian-backed group to access drinking water and wastewater systems, although the exact scope and impact of the attacks are still unclear. CISA has warned that directly connecting programmable logic controllers (PLCs) to the internet through cellular modems can create significant security risks, and has urged water utilities to find and secure internet-exposed PLCs.
The recent attacks have renewed concerns about the cybersecurity weaknesses in U.S. water infrastructure, especially at small and rural utilities that often have limited security staff and resources. In August, CISA urged water utilities to find and secure internet-exposed PLCs after July attacks showed how easily exposed industrial systems can be compromised. Over 100 internet-exposed systems in the U.S. water and wastewater sector got hit by cyberattacks in July 2026, and CISA's response wasn't just an incident report, it was a how-to guide for making sure it doesn't happen to you next.
The pattern behind the July attacks was surprisingly simple. Most of the affected systems were PLCs, small industrial computers that control pumps and valves. Many connected directly to cellular modems and had no firewall or gateway between them and the internet. CISA warns that this type of setup can expose PLCs to serious security risks.
The attacks on small water utilities are just the latest example of the growing threat to the nation's critical infrastructure. As the use of technology increases, so too does the risk of cyberattacks on these systems. It is imperative that the U.S. government takes action to strengthen the cybersecurity of these systems, providing the necessary resources and support to ensure that they are protected from foreign threats.
In response to the recent attacks, CISA has added several vulnerabilities to its Known Exploited Vulnerabilities catalog, including Linux kernel flaws. The agency has also urged water utilities to take steps to secure their systems, including removing remote access when it is unnecessary and securing it when it is necessary.
The recent attacks on small water utilities highlight the need for a coordinated effort to strengthen the cybersecurity of the nation's critical infrastructure. The government, industry, and individuals must work together to address this growing concern and ensure that our water infrastructure is protected from foreign threats.
