What’s new: Pro-Russian hackers have been identified as responsible for a cyber attack on the Bremanger dam in Norway, which occurred in April 2025. The hackers compromised the dam’s operational systems and opened outflow valves, resulting in the release of over 7.2 million liters of water. This incident was characterized as a demonstration of hacking capabilities rather than an attempt to cause physical damage.
