Confirmed ransomware attacks in Norway by year
The current year is a partial count. Confirmation lags the attack itself, so recent months keep filling in after the fact; read a low figure for the latest year as incomplete rather than as a decline.

Ransom payment outcomes in Norway
Among the 5 confirmed incidents in Norway where the outcome is on the public record, 0 paid and 5 refused, a disclosed payment rate of 0%. The remaining 24 carry no public statement either way. Victims that pay have every incentive to stay quiet and public bodies are the most likely to announce a refusal, so treat this as the disclosed rate, not the true one. The ransomware payment rate analysis explains how the disclosed rate has moved since 2018 and how it compares with incident-response firm samples.
Largest confirmed ransomware attacks in Norway by records exposed

Frequently asked questions
How many ransomware attacks in Norway have been confirmed?
Ransomnews has confirmed 29 ransomware attacks in Norway since March 2019, including 3 so far in 2026. Each one is verified against a public source such as a breach notification, regulatory filing or press report. The true total is higher, because many victims never disclose; confirmed counts are a floor, not a ceiling.
Which ransomware group is most active in Norway?
Akira, with 2 confirmed victims, followed by REvil (2) and 8Base (1). These are confirmed victims, not leak-site claims, counted among the 20 incidents where the operator is attributed.
Which sector is hit most by ransomware in Norway?
Manufacturing, with 7 confirmed incidents (24% of the total). Transportation follows with 5, then Other with 4.
Which cities in Norway have the most confirmed ransomware attacks?
Oslo (13), Ålesund (2), Gjøvik (1), Glostrup (1), Haugesund (1). City is recorded where the victim organisation is headquartered or the incident was reported, so distributed organisations are counted once.
How often do ransomware victims in Norway pay the ransom?
Among the 5 confirmed incidents in Norway with a public outcome, 0 paid and 5 refused, a disclosed payment rate of 0%. Most victims never state whether they paid, and those who pay have the least reason to say so, so the disclosed rate understates real payment behaviour. The payment rate analysis tracks this figure since 2018.
What is the largest confirmed Norway ransomware attack by records exposed?
Hurtigruten (Tromsø, Norway, December 2020), with 4,017 records exposed according to securityweek.com. Record counts exist only where a source disclosed them, so this ranks disclosed impact.
How to read this page. Every incident counted here was verified by Ransomnews against at least one public source. Leak-site listings alone do not qualify, because operators inflate, duplicate and occasionally fabricate claims, so these totals are a defensible floor rather than a full census. Records exposed and ransom outcomes appear only where a named source disclosed them. The page is regenerated from the live database, which refreshes weekly.
