The cybercriminals group BlackHat has claimed ransomware attacks against Creos, an energy network operator, and the supplier Enovos in the night of July 22. Both companies are under the Encevo Group, an energy corporation owned by the government of Luxembourg and several other companies, including China Southern Power Grid International. Creos helps run the country’s electricity and gas network infrastructure, while Enovos is Luxembourg’s main supplier. Encevo Group admitted in a press release that certain data were stolen and blocked by the hackers. Law enforcement and competent governmental authorities in Luxembourg are investigating the incident.
