On December 19, 2025, Denmark's Defence Intelligence Service made an announcement that should concern every critical infrastructure operator worldwide: pro-Russian hackers had successfully attacked a Danish water utility, remotely manipulating water pressure controls. Local officials said this led to pipe bursts affecting several dozen households. And a small waterworks serving several villages south of Copenhagen became the latest example of how state-backed cyber actors are

The recent revelation that Chinese state-sponsored threat actors maintained unauthorized access to a Massachusetts utility's operational technology network for nearly a year serves as a stark reminder of the evolving threat landscape facing critical infrastructure. The Littleton Electric Light & Water Department discovered its systems were breached just before Thanksgiving in 2023, with investigations revealing that Volt Typhoon had been present in their systems since Februar

Protecting critical infrastructure from cyber threats is no longer just about preventing operational disruption or data theft. In some cases, it's about preventing your systems from becoming intelligence assets that enable physical military strikes. Recent findings from Amazon Threat Intelligence reveal a disturbing evolution in nation-state tactics: adversaries are systematically compromising operational technology systems not to damage them directly, but to gather real-time

The February 2024 Anycubic incident , where hackers compromised 3D printers worldwide to warn users that their devices were exposed to critical security vulnerabilities through the company's MQTT service API, represents more than just another IoT security breach. It signals a fundamental shift in the operational technology threat landscape, one where additive manufacturing systems have evolved from prototyping tools into critical production infrastructure, yet remain unprotec

The Canadian Cybersecurity Network (CCN)  just released their comprehensive State of Canada OT Report 2025, and the findings reveal a cybersecurity landscape that should concern every industrial organization operating in North America. With over 45,000 cybersecurity professionals contributing to this analysis, the report paints a lousy picture of escalating threats against Canada's critical infrastructure, threats that extend far beyond national borders. This means that other

In our highly connected world, Operational Technology (OT) cybersecurity has never been more critical. As essential services like manufacturing, smart buildings, and healthcare increasingly rely on digital systems, they also become vulnerable to cyber attacks. The true cost of these attacks goes beyond initial financial damage; they can lead to significant downtime, safety risks, and lasting harm to an organization's reputation. This post explores the financial implications o
