Yesterday, the Norwegian National Security Authority (NSM) issued a statement warning that some of Norway's most important websites are being blocked by distributed denial-of-service (DDoS).

Further, the statement explains that an organized criminal pro-Russian group is suspected of being behind the attacks.

DDoS attacks, a cyberattack that overwhelms internet servers with many requests and garbage traffic, render hosted sites and services unavailable for legitimate users and visitors.

These low-cost hacks are part of ongoing cyber-warfare between pro-Russian and pro-Ukrainian hackers.

This attack was most recently directed at the Lithuanian government and its national transport services. Russian hackers attacked Italy and Romania earlier to provide full-spectrum support for Ukraine.

The Norwegian authorities have reported attacks on large companies providing essential services to the public.

Sofie Nystrom, director of NSM, stated that similar attacks had been reported in other countries. However, none have had lasting consequences.

"The attacks will continue to be able to create uncertainty among the population and give us the impression that, in the current political environment in Europe, we are still a part of it."

NSM provides guidance resources to help system administrators mitigate the effects of these attacks.

NSM's announcement does not mention who the hackers were or what services they targeted. However, we were able to find some targeted websites via the Telegram channel of Legion – Cyber Spetsnaz RF.

Legion, like other hacktivist groups, recruits volunteers to assist with attacks. This is the same group that recently attacked Lithuania.

Legion is also believed to be affiliated, in part, with Killnet, another group that attacked Romania, Italy, and other countries through DDoS attacks in the past months.

Russian hackers claim that some of the targets in Norway are the Norwegian national police, the state's public service portal, the NAV site (immigration), Altinn digital government portal, and the UDI portal.

Two main reasons why the latest wave of cyberattacks on Norway has been disrupted.

First, Norway stopped the passage of 20 tonnes of goods from Russia to Svalbard Island, destined for Russian miners living in the archipelago.

To help Ukraine resist the ongoing Russian invasion, Norway donated long-range rocket artillery (MLRS) systems and 5,000 shells.

Experts believe DDoS attacks will continue to cause global political instability due to their simplicity and low cost.
