Largest Recorded Cyberattacks at Danish Energy Infrastructure

May 11, 2023

This past May, Danish critical infrastructure suffered the most extensive cyber-related attack it ever experienced in Denmark to date. In all, 22 companies that operate parts of the Danish energy infrastructure ended up compromised in a coordinated attack, according to a report by SektorCERT. The result was the attackers gained access to some of the companies’ industrial control systems and several companies had to go into island mode operation.

The attacks began on May 11, followed by 10 days of inactivity. A second wave of attacks began on May 22 when SektorCERT received an alert that one of its members had downloaded new firewall software over an insecure connection. Whether the attack came from servers associated with a unit of Russian military hackers popularly known as Sandworm cannot be said with certainty. Individual indicators of this have been observed, but we have no opportunity to neither confirm nor deny it, states the SektorCERT report.

Paralyzing Cyberattack Hits Danish Cloud Service Companies

August 18, 2023

CloudNordic has told customers to consider all of their data lost following a ransomware infection that encrypted the large Danish cloud provider’s servers and “paralyzed CloudNordic completely,” according to the IT outfit’s online confession. The hackers shut down all of CloudNordic’s systems, wiping both company and customers’ websites and email systems, even the backups and production data were trashed. CloudNordic isn’t prepared, nor able, to pay a ransom, presumably to restore the information and systems. CloudNordic says its “best estimate” is that the infection happened as servers were being moved from one datacenter to another.

Customers with Azero are also affected. CloudNordic and Azero are owned by Denmark-registered Certiqa Holding, which also owns Netquest, a provider of threat intelligence for telcos and governments.
