Sweden urges energy sector to tighten security; no specific threat
By Johan Ahlander
STOCKHOLM, Feb 26 (Reuters) - Sweden has told its energy industry to raise security levels following a recent cyberattack on Polish infrastructure, although this was not in response to a specific threat, the Nordic country's signal intelligence agency said on Thursday.
Regional Security and Market Implications
Swedish TV4, citing unnamed sources, earlier reported that authorities in the Nordic nations were investigating a threat to the region's energy providers from actors with likely links to a foreign power.
Sweden’s Enhanced Vigilance (FRA guidance)
"We have recently been calling on the actors in the Swedish energy sector to be more vigilant," Ola Billger, head of communication at Sweden's National Defence Radio Establishment (FRA), told Reuters.
"We did so last Friday and we also called on the energy sector to take certain measures to make Sweden a more difficult target," Billger said.
Poland Cyberattack Context
Poland's government last month said that it had managed to ward off a large cyberattack at the end of December that was aimed at disrupting communications between renewable installations and power grid operators.
Baltic Sea Infrastructure Incidents
Nordic police and intelligence agencies in recent years investigated damage to several underwater gas pipelines, power lines and telecoms cables in the Baltic Sea, some of which were found to be caused by deliberate attacks or sabotage.
Svenska kraftnät Actions
Operator Responses and Coordination
Sweden's electricity grid operator, Svenska Kraftnat, told Reuters it had increased vigilance at its facilities, but declined to say when it had done so.
Civil Defence Coordination
"We are aware of the information and we cooperate with other government agencies," a spokesperson for Sweden's Ministry of Civil Defence told Reuters.
Norway’s Gassco Update
Norway's Gassco, which is responsible for a vast system of pipelines and terminals supplying natural gas to Europe, said there was currently no immediate threat to Norwegian gas infrastructure.
Lithuania’s Crisis Stance
Lithuania's National Crisis Management Centre said energy security remained a national priority but that it had not received any new reports of threats.
Pending Agency Comments
Norway's security police agency, the Norwegian National Security Authority and the Danish national security and intelligence service did not immediately respond to requests for comment.
