The recent cyber attack on Nova Scotia Power (NSP) has become a stark reminder of the vulnerabilities plaguing utility infrastructure cybersecurity. The Canadian electricity provider, which serves over half a million residents in Nova Scotia, confirmed that it experienced a major data breach, compromising sensitive customer information and disrupting key digital services.
The breach, detected on April 25, triggered an immediate incident response. NSP swiftly shut down and isolated affected servers to prevent further intrusion. Despite these rapid containment efforts, critical services—including the company’s customer service phone line and online billing portal—were temporarily shut down, leaving many Nova Scotians without access to vital utilities.
“We detected unusual activity and immediately initiated our incident response plan,” NSP stated. “While our investigation is ongoing, we have identified that certain customer personal information was accessed and taken by an unauthorized third party.”
This incident is a textbook case of how lapses in utility infrastructure cybersecurity can have real-world impacts. While NSP confirmed that physical power delivery remained unaffected, the compromise of digital infrastructure caused severe disruptions to customer engagement and billing operations.
NSP, a privately owned company under Emera Inc., is regulated by the Nova Scotia Utility and Review Board. Based in Halifax, it plays a central role in the province’s energy grid, making it a high-value target for cybercriminals.
To determine the scope and origin of the breach, NSP brought in external cybersecurity experts and informed law enforcement authorities. Although the company has not yet disclosed whether the attack involved ransomware, how much data was stolen, or who may be responsible, the lack of clarity underscores the complex and often slow-moving nature of digital forensics in critical infrastructure environments.
The online customer portal “MyAccount” was among the affected systems. NSP has since paused billing operations and promised to address potential duplicate payments as part of its recovery plan.
Why Critical Infrastructure Must Be Protected
Cyber attacks on utility providers don’t just threaten data—they threaten lives, economies, and national security. Critical infrastructure systems, such as electricity, water, and telecommunications, form the backbone of modern society. A single breach can paralyze services, delay emergency responses, and erode public trust.
As utilities become more digitized, their attack surfaces expand, and the risks increase. Disruptions like the one at NSP show why it’s essential to implement layered cybersecurity strategies that cover both IT and OT (operational technology) environments. From insider threats to sophisticated nation-state actors, the threat landscape is evolving—and infrastructure protection must evolve with it.
