Valve Opened in Norway Dam Attack
INCIDENT
Hackers were able to get into the systems of a Norwegian dam this past April and open its water valve at full capacity.
The breach occurred at the Lake Risevatnet dam near the city of Svelgen in Southwest Norway. Attackers compromised a weak password on the web-accessible control panel and were able to open valves all the way at the dam. The valve ran at full capacity (497 m3/s above normal) for at least four hours before workers at the dam discovered the unauthorized change. The hack didn’t put anyone in danger, barely moving water output over the dam’s minimum water flow requirement, according to a report in the Norwegian energy news outlet Energiteknikk.
