Authorities urge greater vigilance
Sweden has instructed companies in its energy sector to increase security measures following a recent cyberattack targeting Polish infrastructure. Officials clarified that the move was precautionary and not tied to a specific imminent threat.
The National Defence Radio Establishment, Sweden’s signal intelligence agency, said it recently encouraged energy providers to heighten vigilance. “We have called on the actors in the Swedish energy sector to be more vigilant,” said Ola Billger, head of communications at the agency, adding that additional protective steps were recommended to reduce potential vulnerabilities.
Regional concerns in the Baltic area
Poland disclosed last month that it had successfully blocked a major cyberattack at the end of December aimed at disrupting communication between renewable energy installations and grid operators.
In recent years, Nordic police and intelligence services have examined damage to underwater gas pipelines, power cables and telecommunications infrastructure in the Baltic Sea. Some of those incidents were determined to involve deliberate sabotage.
Infrastructure operators respond
Sweden’s national electricity grid operator, Svenska Kraftnät, confirmed it had strengthened vigilance at its facilities but did not specify when the heightened measures were implemented.
The Swedish Ministry of Civil Defence stated it was coordinating with other government agencies and monitoring developments closely.
Elsewhere in the region, Norway’s Gassco, which oversees a major network of pipelines and terminals supplying gas to Europe, said it faced no immediate threat to its infrastructure. Lithuania’s National Crisis Management Centre likewise indicated that while energy security remains a priority, no new threat reports had been received.
Security agencies in Norway and Denmark did not immediately provide comment.
