Patrick White, a seasoned water reporter for the Globe and Mail, delves into the rising threat of cyberattacks targeting water treatment plants. He discusses why these breaches differ from other infrastructure hacks and highlights alarming incidents, including recent politically motivated attacks in the U.S. The conversation also underscores the vulnerabilities faced by smaller municipalities, where lack of funding hampers cybersecurity efforts. White emphasizes the critical need for governments to step up protection of our essential water resources.
Cyber attacks on water treatment plants are increasingly driven by political motivations rather than financial gain, posing new risks to public health.
The shift from manual to digital control in water systems has heightened security vulnerabilities, necessitating improved cybersecurity measures and public awareness.

Rising Threat of Cyber Attacks on Water Systems
Cyber attacks on water systems have recently surged, highlighting significant vulnerabilities in critical infrastructure. Instead of the typical ransom demands often seen in other types of cybercrime, many of these incursions appear to have political motivations. For example, attacks in places like Pennsylvania and Texas have been linked to state-sponsored groups aiming to undermine local infrastructure rather than merely extorting money. This shift in tactics raises the stakes, as compromised water systems not only threaten public health but can also lead to broader environmental and societal chaos.
Vulnerabilities in Digital Water Infrastructure
The transition from manual to digital control in water systems has created new security risks that hackers are increasingly exploiting. Digital systems now oversee processes previously managed through hands-on methods, making them susceptible to cyber threats. Vulnerabilities arise when remote access points are not properly secured, often leaving default passwords unchanged or allowing unauthorized digital access. As these systems become integrated with various technologies, the complexities increase, consequently elevating the risk of significant failures.
Implications and Urgency for Cybersecurity in Water Management
The implications of water system hacks can be serious, disrupting essential services and even threatening public health. For instance, a breach can lead to unsafe drinking water or a total loss of access to clean water, which can fundamentally destabilize communities. Governments and municipalities need to bolster their cybersecurity efforts, especially smaller municipalities that often lack the financial resources for proper defenses. Enhanced collaboration, better funding for cybersecurity initiatives, and greater public awareness are critical to safeguarding the integrity of water systems as threats continue to evolve.
In recent years, cyber attacks have become increasingly frequent and wide-reaching. In 2023, the Toronto Public Library, Canada’s largest-circulation library system, was the subject of a ransomware attack. Its systems were down for months, and the library was taken back to a pre-internet age. Now, hackers are turning to water treatment plants – and it’s not money they’re after.
Patrick White is the Globe’s water reporter. He’s on the show to talk about how these attacks have been unfolding, why they look different from other kinds of infrastructure hacks, and how governments are preparing for this new threat.
