Svenska kraftnat, Sweden’s national grid operator, has confirmed it suffered a ransomware attack, with around 280 GB of internal data reportedly stolen by a group named Everest, believed to be Russian-speaking but not state-sponsored. While the power system remains unaffected, the agency is investigating the leak’s implications. Everest has gained notoriety due to previous, less significant breaches, which raises questions about its capability and intent. This incident underscores the growing threat of cyberattacks on critical infrastructure and highlights the need for robust cybersecurity measures, as attackers increasingly target national utilities, potentially endangering public safety and national security.
