- Svenska kraftnät hit by ransomware; 280 GB of internal data allegedly stolen
- The electrical system is not affected; an investigation into a data breach is underway
- The Everest Group claimed responsibility; believed to be Russian-speaking and not state-funded
Svenska kraftnät, the Swedish national network operator, has confirmed that it was the victim of a ransomware attack and data breach, and is now being extorted for money.
In a brief statement on its website, the company said it was now investigating “to find out what information was disclosed and how it might affect us.”
“We see no indication that the electrical system is affected,” Cem Göcgören, head of information security at Svenska kraftnät, said in a machine-translated statement.
Everest
Svenska kraftnät is Sweden’s national grid operator, a government agency responsible for the maintenance and operation of the country’s electricity transmission system.
“Our current assessment is that critical systems have not been affected,” Göcgören said. “At this time we will not comment on the perpetrators or motives until we have confirmed the information.”
Although it did not specify who the perpetrators of the threat were, what type of files they stole or how much money they are demanding in return, The file discovered that a group called Everest had claimed responsibility for the dark web, claiming to have stolen around 280 GB of internal files, without going into specific details.
Everest is a known ransomware organization, but it does not have the image of a dangerous group.
In fact, it became the laughing stock of the cybersecurity community after breaking into Mailchimp in 2024 because it stole such a small batch of company data (around 767 MB of information).
One person shared their thoughts on social media, describing the breach as affecting “like a customer”, while the other commented that the breach involved “probably 300 milliseconds of mailchimp data. It’s likely a customer’s emails were leaked.”
Everest is not a state-sponsored group, but because its members speak Russian, security researchers believe the group is located there.
