Cyber Attack Hits the Largest US Public Water Utility: A Wake-Up Call for Critical Infrastructure
On October 3, 2024, American Water, the largest regulated water utility in the United States, was struck by a significant cyber attack, forcing the company to disconnect certain systems to contain the breach. Based in Camden, New Jersey, American Water provides essential water and wastewater services to over 14 million people across 14 states and 18 military facilities. The attack sent shockwaves through both the water sector and cybersecurity communities, raising urgent questions about the vulnerability of critical infrastructure to cyber threats.
Impact of the Cyber Attack on American Water
The attack was first reported in a Form 8-K regulatory filing with the U.S. Securities and Exchange Commission (SEC), where American Water disclosed that it had detected unauthorized activity within its computer networks and systems. The company immediately activated its cyber incident response protocols, launching an investigation with both internal and external cybersecurity experts.
While the specific details of the attack vector remain undisclosed, American Water responded by taking critical steps to mitigate further damage. This included disconnecting systems, particularly the MyWater customer portal, to protect customer data and prevent any additional harm to its IT environment.
Disconnection of Services: The shutdown affected customers’ ability to access services like bill payments, and certain appointments were rescheduled due to the incident. Despite the disruption, American Water assured its customers that there would be no late fees or disconnection fees imposed during the outage, particularly for the rest of October. The company worked diligently to restore its services, with the MyWater portal and the call center resuming normal operations by October 10, 2024.
No Compromise to Water Safety: Most importantly, American Water confirmed that the attack did not compromise the safety of drinking water, nor did it have any material impact on the company’s operations or financial condition. “None of our water or wastewater facilities or operations have been negatively impacted,” the company stated, highlighting its ongoing efforts to restore impacted systems after ensuring the safety of its cyber infrastructure.
Ongoing Investigation and Cybersecurity Response
American Water has yet to disclose whether the cyber attack involved ransomware or if customer data was compromised. The investigation is still underway, and the company remains committed to providing updates as more information becomes available.
In its online statement, the water utility reiterated its commitment to cybersecurity and noted that it had taken additional protective measures. The company is also working closely with relevant authorities, including law enforcement and regulatory bodies, to investigate the breach thoroughly.
The Growing Threat to U.S. Water Utilities
American Water is not the first water utility in the U.S. to experience a cyber attack. The nation’s water systems have become prime targets for hackers, particularly state-sponsored cybercriminals and politically motivated hacktivists. Recent incidents highlight the increasing pressure on critical infrastructure to bolster their cyber defenses.
- September 2024: Kansas Water Utility Breach
Just days before the American Water attack, a water utility in Arkansas City, Kansas, was forced to revert to manual operations following a cyber attack. The attack on the Kansas facility coincided with an alert from the Water Information Sharing and Analysis Center (WaterISAC), warning of potential Russian cyber threats targeting U.S. water systems. - November 2023: Pennsylvania Water Utility Hack
In another high-profile incident, an Iranian hacktivist group, Cyber Av3ngers, breached a Pennsylvania water utility by exploiting vulnerabilities in Israeli-made Unitronics programmable logic controllers (PLCs). This attack underscored the susceptibility of critical infrastructure to foreign state-sponsored hackers.
Cybersecurity Expert Insights: Commenting on the frequency of such breaches, James McQuiggan, a Security Awareness Advocate at KnowBe4, remarked, “For cyberattacks and breaches, the key takeaway for organizations is that the question is not ‘if’ but ‘when’ a breach will occur, and are they prepared?”
Key Lessons from the American Water Cyber Attack
The attack on American Water highlights several important lessons for other utilities and organizations that manage critical infrastructure:
- Preparedness is Essential: No organization is immune to cyber threats, especially critical infrastructure providers. The question isn’t whether an attack will happen but how prepared companies are to mitigate the impact and recover swiftly.
- Robust Cybersecurity Protocols: Organizations must maintain strong cybersecurity and risk management programs, including incident response plans. This will help reduce the potential damage from a cyber attack and possibly prevent subsequent breaches.
- Proactive Measures: Disconnecting affected systems and activating internal protocols as soon as unauthorized activity is detected can limit the extent of a cyber attack. American Water’s quick response likely played a crucial role in preventing further damage.
- Collaboration with Authorities: Cybersecurity incidents should be reported immediately to the relevant regulatory and law enforcement bodies. Working with experts—both internal and external—can accelerate recovery and provide valuable insights for future protection.
- Customer Transparency: American Water’s approach to handling customer communication, including the waiver of late fees and rescheduling appointments, demonstrated a commitment to minimizing the impact on consumers during a cyber crisis.
The Broader Implications for U.S. Critical Infrastructure
The American Water attack serves as a reminder that the U.S. critical infrastructure remains a lucrative target for cybercriminals. Water systems, in particular, are vulnerable due to outdated technology, limited cybersecurity budgets, and the sheer scale of operations.
U.S. authorities, including the Department of Homeland Security (DHS) and the Cybersecurity and Infrastructure Security Agency (CISA), have issued repeated warnings about the potential for cyber attacks on critical infrastructure, especially from foreign adversaries. These agencies work closely with private-sector organizations to strengthen defenses, but the increasing sophistication of cyber threats means there is always more to be done.
