Norway’s domestic security agency confirmed Friday that the Chinese state-sponsored espionage campaign tracked as Salt Typhoon compromised network devices in Norwegian organizations.

The disclosure was made in the Norwegian Police Security Service’s (PST) annual threat assessment for 2026. The agency’s director general, Beate Gangås, said Norway was “facing its most serious security situation since World War II,” citing pressure from multiple foreign intelligence services.

Salt Typhoon is the name U.S. and allied authorities use for a Chinese cyber espionage campaign that has focused heavily on breaching telecommunications and other critical infrastructure. In its report, PST said the actor has exploited vulnerable network devices in Norway.

Gangås said foreign states — particularly China, Russia and Iran — are “conducting intelligence operations and employing hybrid tactics in Norway to undermine our resilience,” stressing the “vital” need for stronger protective security, intelligence and situational awareness.

The assessment said Chinese security and intelligence services have strengthened their ability to operate in Norway, including through cyber operations and human intelligence collection, adding that “the primary intelligence threat from China is in the cyber domain.”

China is described as posing a “substantial” threat and is expected to continue improving its efforts to collect intelligence and map Norwegian digital infrastructure.

PST also warned that China is “systematically” exploiting collaborative research and development projects to bolster its own military capacity and security capabilities.

Salt Typhoon has been linked to significant breaches of telecommunications providers and other critical infrastructure abroad. U.S. officials have said the campaign allowed attackers to intercept communications linked to senior political figures during the 2024 presidential race, including Donald Trump and JD Vance.

Last year, more than a dozen allied countries issued a joint advisory blaming three Chinese technology companies for enabling the espionage campaign, saying the intrusions were used to track the communications and movements of specific targets.

While China dominates the cyber threat picture, PST said Russia remains the principal overall threat to Norway’s security. The agency cited sustained espionage, mapping of critical infrastructure, pressure on Ukrainian refugees, covert intelligence operations using civilian vessels and the risk of sabotage.

Russian intelligence has been “closely monitoring military targets and allied activities and capabilities in Norway for many years,” the report said, adding that the tense geopolitical situation in Europe is likely to drive increased activity.

PST said it expects that to include more Russian cyber operations, influence campaigns and attempts to recruit sources via digital platforms in 2026, describing cyber activity as an integral part of Moscow’s broader intelligence effort alongside traditional espionage and influence work.

“The tense geopolitical situation in Europe means that Russian intelligence has several areas of interest in relation to Norway and other NATO countries. Given the increase in military targets on Norwegian soil, the stronger allied presence, and additional military exercises, we anticipate heightened activity from Russian intelligence services,” the agency added.

Iranian intelligence services are also expected to carry out intelligence and influence operations in Norway, the PST said, warning the regime may attempt to target Western interests through property damage, targeted assassinations, terrorist acts or destructive cyber operations.

The PST said the assessment underlines the need for closer cooperation between authorities and the private sector, particularly operators of critical infrastructure, as foreign intelligence services increasingly combine cyber operations with more traditional espionage and influence campaigns.
