Norwegian authorities have attributed a suspected sabotage incident at a hydropower dam in April 2025 to pro-Russian hackers. According to Norway's spy chief and police officials, the hackers briefly took control of the dam on April 7, opening a floodgate and releasing water at a rate of 500 liters per second for nearly four hours. While no physical damage was reported, the incident caused disruptions to the energy supply and raised concerns about increasing cyber threats to critical infrastructure. Norwegian officials have emphasized the need for heightened vigilance in response to these cyberattacks.
