In April 2025, hackers took control of the Bremanger dam in Norway using a single weak password. By accessing a web-exposed SCADA system, they opened a floodgate and released 7.2 million liters of water over four hours. No advanced malware or zero-day exploit was needed—just basic access to a system that should never have been exposed to the internet.

This video explains how the attack happened, why weak credentials and exposed OT systems remain the biggest risk to critical infrastructure, and what could have stopped it instantly. It also shows how modern Zero Trust architecture, passwordless authentication, and network cloaking can eliminate these attack paths entirely.

BlastWave’s BlastAccess and BlastShield secure remote access and make OT systems invisible to attackers, preventing both credential-based attacks and AI-driven reconnaissance.

Learn how this attack—and dozens more like it—could have been prevented in Hackopedia Volume 1.
