Overview

• Police Security Service chief Beate Gangås publicly blamed pro-Russian hackers at the Arendalsuka forum, marking Oslo’s first formal attribution of a domestic infrastructure attack to Moscow’s proxies.
• Investigators report that on April 7 the attackers accessed the Lake Risevatnet dam’s remote-control system and released about 500 litres of water per second for four hours without causing injuries.
• Norway’s National Criminal Investigation Service corroborated the breach in June after hackers posted a watermarked three-minute video of the dam’s control panel on Telegram.
• Intelligence chief Nils Andreas Stensønes warned that Russia is Norway’s most unpredictable security threat and said the dam intrusion reflects a broader pattern of disruptive cyber operations across Europe.
• The Russian embassy in Oslo rejected the attribution as politically motivated, accusing Norwegian authorities of inventing a “mythical” sabotage threat.
