Russian hackers took control of a Norwegian dam this year, opening a floodgate and allowing water to flow unnoticed for four hours, Norway\u2019s intelligence service has said.<\/p>\n
The admission, by the Norwegian Police Security Service (PST), marks the first time that Oslo has formally attributed the cyber-attack in April on Bremanger, western Norway, to Moscow.<\/p>\n
The attack on the hydropower dam, which produces electricity, released 500 litres (132 gallons) of water a second for four hours until the incident was detected and stopped.<\/p>\n
The head of PST, Beate Gang\u00e5s, said on Wednesday: \u201cOver the past year, we have seen a change in activity from pro-Russian cyber actors.\u201d The Bremanger incident was an example of such an attack, she added.<\/p>\n
\u201cThe aim of this type of operation is to influence and to cause fear and chaos among the general population. Our Russian neighbour has become more dangerous.\u201d<\/p>\n
The incident did not cause any injuries or damage because the water level of the river and the dam, which is close to the town of Svelgen, was a long way below flood capacity.<\/p>\n
The alleged perpetrators reportedly published a three-minute video, watermarked with the name of a pro-Russian cybercriminal group, on Telegram on the day of the attack.<\/p>\n
Kripos, Norway\u2019s organised crime police unit, told the Aftenposten newspaper it was \u201caware this group brought together several actors who commit crime in the cyber domain\u201d and had been linked to several cyber-attacks against businesses in the west in recent years.<\/p>\n
Gang\u00e5s said: \u201cRussian intelligence services spend significant resources identifying, cultivating and recruiting contacts in Norway. Norwegian citizens could be good sources of information for them.\u201d<\/p>\n
Intelligence services in Norway, which produces the majority of its electricity using hydropower dams, had previously warned of the potential risk of such attacks on energy infrastructure.<\/p>\n
Norway and Russia share a 123-mile (198km) border, with a crossing at Storskog, Europe\u2019s only open Schengen border with Russia.<\/p>\n
The Russian embassy in Oslo said Gang\u00e5s\u2019s statements were \u201cunfounded and politically motivated\u201d.<\/p>\n
It told Reuters news agency: \u201cIt is obvious that the PST is unsuccessfully trying to substantiate the mythical threat of Russian sabotage against Norwegian infrastructure this year, which it itself invented in its February (annual) report.\u201d<\/p>\n
