More than 100 water systems were hit in July cyberattacks, marking a significant escalation in the threat landscape for the water and wastewater sector. The attacks are suspected to be linked to Iran and highlight the vulnerability of operational technology systems, which are increasingly dependent on OT systems.
Over 100 water systems in the US were compromised in a recent surge of cyberattacks. The attacks targeted internet-exposed systems in the Water and Wastewater Systems Sector via PLCs connected to cellular modems. The attacks are suspected to be linked to Iran and targeted facilities in at least a dozen states, including small rural utilities. The attackers are using AI-generated exploitation scripts to break into systems and are taking advantage of the fact that many systems are not adequately secured. The attacks pose a significant threat to the security of the sector and the safety and well-being of communities. The federal government has not attributed the attacks to anyone due to challenges in attribution in cyber incidents. The government has recommended disconnecting PLCs from the internet and implementing robust access controls to mitigate the impact of the attacks. The water sector must take proactive steps to enhance its security posture to prevent future breaches.
In a recent surge of cyberattacks, more than 100 water systems across the United States were compromised, marking a significant escalation in the threat landscape for the water and wastewater sector. According to the Cybersecurity and Infrastructure Security Agency (CISA), these attacks targeted over 100 internet-exposed systems in the Water and Wastewater Systems (WWS) Sector, commonly via programmable logic controllers (PLCs) connected directly to a cellular modem. This alarming trend has left the water sector grappling with the consequences of these cyberattacks, which are not only a concern for the security of the sector but also for the safety and well-being of the communities they serve.
The attacks, which are suspected to be linked to Iran, targeted water and wastewater facilities across at least a dozen states, including small, rural utilities in Minnesota, Michigan, Georgia, South Dakota, and New Jersey. The scale of the attack is a stark reminder of the vulnerability of operational technology (OT) systems, which were designed for closed, physical environments and were never intended to be reachable from the open internet. The attackers, who are believed to be using AI-generated exploitation scripts to break into these systems, are taking advantage of the fact that many of these systems are not adequately secured, leaving them open to exploitation.
"It's very serious," said Matt Hartman, chief strategy officer at the Merlin Group and former acting head of cyber at CISA. "What stands out isn't any single incident. It's the scale. More than 100 water systems with internet-exposed assets were hit in a single month, which points to a systemic vulnerability across the sector, not a run of isolated, unlucky targets." Hartman's words highlight the gravity of the situation, emphasizing that the scale of the attack is a concern that goes beyond individual incidents.
The attackers' strategy is not only to breach these systems but also to exploit them for malicious purposes. "These are test runs for a larger-scale attack," warned John Gallagher, VP at Viakoo, an OT and IoT cybersecurity provider. Gallagher's statement underscores the threat posed by these attacks, which are not only a concern for the security of the sector but also for the potential consequences of a larger-scale attack.
The federal government has not attributed the attacks to anyone, citing the challenges of attribution in cyber incidents. "Attribution in cyber incidents is inherently difficult and often takes time," said Hartman. "Adversaries deliberately obscure their infrastructure, reuse tools and techniques, and route activity through compromised systems, so the government needs to be diligent before publicly assigning responsibility." Despite the challenges, the government has taken steps to mitigate the impact of these attacks, recommending that organizations disconnect PLCs from the internet and ensure any remote access goes through a VPN or gateway device rather than connecting directly to the PLC.
The attacks have also raised concerns about the security of critical infrastructure, which is increasingly dependent on OT systems. "Iran-affiliated actors and adversaries are actively targeting a wide swath of operational technology because these PLCs underpin essential health, safety, and critical infrastructure across society," said Cynthia Kaiser, SVP at Halcyon Ransomware Research Center. Kaiser's statement highlights the threat posed by these attacks, which are not only a concern for the security of the sector but also for the safety and well-being of the communities they serve.
In light of these attacks, it is essential that the water sector takes steps to enhance its security posture, including disconnecting PLCs from the internet and implementing robust access controls. "From a defender's perspective, the 'who' matters less in the immediate term than understanding how the attacks are occurring and taking steps to stop them," said Hartman. By taking proactive measures to address these vulnerabilities, the water sector can mitigate the risk of future attacks and ensure the security of its operations.
In conclusion, the recent surge of cyberattacks against water systems across the United States is a growing concern for the sector, highlighting the vulnerability of operational technology systems. The scale of the attack is a stark reminder of the need for robust security measures to protect these systems and prevent future breaches. As the water sector continues to grapple with the consequences of these attacks, it is essential that it takes proactive steps to enhance its security posture and prevent future breaches.
