NSM issues nine concrete recommendations to help Norwegian organisations prevent and handle denial-of-service attacks
- Any organisation with a website or online service can be hit by an attack that makes that service unavailable.
- NSM says organisations must list all systems and services reachable on the internet and know whether they sit on internal servers, in a data centre, or in the cloud.

NSM: Denial-of-service attacks are disruptive but not dangerous – no one gains access to systems
- NSM's section director Martin Albert-Hoff says DDoS attacks are not dangerous, just a nuisance: attackers flood a website with so much traffic that it grinds to a halt, but no one gets inside the systems.
- The attacks rarely last long and usually cause little lasting damage, though they can hit time-sensitive systems and result in financial losses.

Norway's NSM advises against quantum key distribution, urging all organisations to migrate to post-quantum cryptography by 2030
- Norway's security authority NSM says clearly: do not use QKD. Use post-quantum cryptography instead — a new kind of mathematical encryption designed to resist attacks from quantum computers.
- The deadline is 2030: powerful quantum computers could arrive during the 2030s, and attackers can already store encrypted data today and decrypt it later — so migration must start now.

Norway's NSM warns: AI models can now autonomously discover and exploit zero-day vulnerabilities
- Anthropic's new AI model Mythos was independently tested by the UK government body AISI in April 2026. It is the first AI system to complete a full 32-step digital attack from start to finish, succeeding at an average of 22 out of 32 steps.
- The previous top model, Claude Opus 4.6 — already available to the public since February 2026 — averaged 16 steps and never finished the full chain, but can already find previously unknown security flaws on its own.

Norway's NSM warns of phishing attacks targeting Signal users in justice, defence and foreign affairs sectors
- Someone is pretending to be Signal support and trying to trick users into giving up their PIN. With the PIN, an attacker can read contact lists and closed group chats.
- Norwegian government staff, defence workers and journalists are particularly at risk, as Signal is widely used in those sectors.

NSM finds no significant increase in cyber risk from the Middle East conflict, but warns of indirect threats through foreign suppliers
- Norway's NSM says the Middle East conflict has not noticeably raised the cyber threat to Norwegian organisations so far, but warns the situation could change quickly.
- The main risk is indirect: if hackers attack the foreign cloud or software companies that Norwegian organisations rely on, Norwegian systems could be knocked out without being targeted directly.

NSM's Risk 2026 report finds systematic and sector-wide security deficiencies in Norwegian organisations
- NSM's 2026 annual report finds that hostile actors are more aggressive and more technically advanced than before, while Norwegian organisations have not done enough to protect themselves.
- A recurring problem is that many organisations do not have up-to-date emergency plans – plans for what to do if something goes wrong. This applies across all industries.
