The largest publicly traded water utility in the US, American Water, found itself in a state of disarray after a cyberattack on October 3 led to the company shutting down some of its systems and services, rendering its website inaccessible. With a customer base of over 14 million spread across 14 states and 18 military installations, the impact of the attack was significant for American Water. The company detected unauthorized activity within its computer networks and systems, prompting it to activate incident-response protocols and engage third-party cybersecurity experts to contain and mitigate the attack.
The repercussions of the cyberattack were far-reaching, affecting not only the company’s online customer-facing platforms but also its telecom systems. The American Water website displayed white pages with a “Forbidden 403” message, indicating a complete shutdown of services. Additionally, attempts to reach the media relations team via phone were futile, as the telecommunications system was also down. Despite these disruptions, the company assured that its water and wastewater facilities remained unaffected by the incident at the time.
The incident at American Water shed light on the vulnerabilities faced by critical infrastructure, including water supply and electricity grids, both in the US and abroad. The dire consequences of such attacks were exemplified by previous incidents like the ransomware attack on Colonial Pipeline in May 2021 and the attempted poisoning of a Florida water-treatment facility in February 2021. These events underscored the urgent need for enhanced cybersecurity measures to safeguard essential services and prevent potential harm to the public.
In light of the recent cyberattack on American Water, cybersecurity experts emphasized the importance of bolstering infrastructure security to mitigate the risks posed by digital threats. Akhil Mittal, a senior manager of cybersecurity strategy and solutions, highlighted the potential disruptions to vital services and public safety caused by cyber incidents. Mittal stressed the necessity of swift containment measures, timely restoration of systems, and transparent communication with the public to expedite recovery from such attacks.
The incident at American Water also brought attention to regulatory efforts aimed at fortifying cybersecurity in water utilities. The US federal authorities have been striving to enforce cybersecurity measures, as a substantial portion of the country’s community drinking water systems fail to comply with established regulations. Despite initial efforts to enhance cybersecurity safety across water utilities, regulatory initiatives faced setbacks due to litigation and opposition from various quarters. Moving forward, robust cybersecurity measures and proactive strategies are essential to safeguard critical infrastructure and ensure uninterrupted delivery of essential services.
As American Water grapples with the aftermath of the cyberattack, the focus remains on swift remediation efforts, system restoration, and transparent communication to restore normalcy. The incident serves as a stark reminder of the evolving cyber threats faced by critical infrastructure providers and underscores the imperative of proactive cybersecurity measures to safeguard vital services and public well-being.
