Russian Hackers Seize Norwegian Dam Control in Alarming Cyberattack
August 13, 2025
Norwegian intelligence chief Nils Andreas Stensønes identified Russia as the primary threat to Norway's security, emphasizing that Russia perceives a permanent conflict with the West.
Despite the heightened threat, Norway does not believe its upcoming parliamentary elections will be significantly influenced by foreign powers.
Similar cyber activities by Russia are ongoing across Europe, targeting entities like an IKEA warehouse in Estonia, a shopping center in Poland, and a warehouse in Britain, with plans involving incendiary devices from Germany to Ukraine.
The attack and attribution were publicly highlighted when a video with the dam's control panel and a watermark of a pro-Russian cybercriminal group was posted on Telegram, marking a notable moment since 2022.
Norwegian authorities are publicizing the attribution to warn the public and prevent further attacks, especially given Norway's strategic position and support for Ukraine.
Norwegian police reported that Russian hackers gained control of a dam in Bremanger, Norway, highlighting the rising threat of cyberattacks on critical Western infrastructure.
The Bremanger dam, located about 150 km north of Bergen and not used for energy, was likely exploited due to a security vulnerability from a weak password, illustrating the vulnerabilities in critical infrastructure.
Experts warn that these attacks are often meant to demonstrate capabilities rather than cause damage, and Norway is advised to prepare for further hacking attempts.
This incident is part of Russia’s broader hybrid warfare strategy, which includes cyber espionage and sabotage, similar to the January 2024 Texas water facility breach.
The attack involved unauthorized access to the dam's control system, which lasted nearly four hours and allowed the hackers to slightly increase water flow, likely exploiting a weak password.
A pro-Russian cybercriminal group claimed responsibility, with a video showing the dam's control panel and their watermark posted on Telegram, marking a significant public attribution since 2022.
Norway, a NATO member and major gas supplier to Europe, shares a border with Russia and supports Ukraine, making it a strategic target amid ongoing geopolitical tensions.
