– Hackers managed to install so-called back doors in the IT systems of the two big energy companies, but at present there is no indication that hackers used the back doors, says Jørgen S. Christensen, head of research and Dansk Energi Technology, to the newspaper.
Back doors can be used to remotely control or install malicious code, and it cannot be ruled out that they have caused problems.
– If hackers have been in for more than six months, it’s difficult to track if they’ve been there, how much damage they’ve done, and if they’ve stolen information or installed something that can be activated later, Christensen tells Jyllands-Posten.
You want to strengthen security
Dansk Energi wants an expanded cybersecurity system to be implemented in gas, electricity and heating companies, and that data will need to be stored in the most important infrastructure operations.
The extensive hacker attack became widely known in December last year, but it may have started as early as October 2019, when hackers broke into Texas-based company Solarwind, which supplies IT technology to US authorities and big enterprises.
Come with an update
Solarwinds announced late last year that a foreign state had found a backdoor to the Orion monitoring tool, where the player posted malicious code. When approximately 18,000 of Solarwind’s customers downloaded an update, they were exposed to the risk of perpetrators gaining access to their network. It is not known exactly which companies and authorities have been affected, but the US Department of Commerce and the US Department of the Treasury have been targeted, and the hackers were also able to read the source code from IT giant Microsoft.
In Sweden, state-owned companies Rymdbolaget, Volvo AB and Skanska, among others, have downloaded the current update, but no one has seen stolen data, SVT Nyheter previously reported.
Russia has previously been identified as responsible for the attack, which it denies.

Solarwinds was founded in 1999 in Texas, USA, and offers IT network monitoring services to companies and authorities around the world.
The 3,200-employee company had sales of nearly $ 1 billion in 2019 and is profitable, with a profit margin of $ 453 million.
The share price was hit hard on December 11, when it was announced that it had been targeted by hackers. The value fell from $ 23.6 to $ 14.2 per share.
Employees have testified that safety was not a priority at the company, despite the sensitive clients it has.
