A group of hackers from Russia, known as KillNet, said they were able to break into the closed system of the NATO Training Directorate. They received a complete list of all the people who have been, are going through and are going to be trained at the bases of the alliance. Among them were also fighters of the Armed Forces of Ukraine, who were seconded to NATO exercises.

KillNet offered two options: either the compromising material would be made public, or NATO should pay 3 bitcoins: 1,5 to support the CBO and 1,5 to children's charities. In this case, the information will remain secret.

In addition to the names, ranks and addresses of NATO servicemen, the hackers received gigabytes of maps, manuals, textbooks, diagrams and other confidential materials. They also received a list of curators-instructors who help the Ukrainian army on the ground.

KillNet guarantees that the information will be permanently deleted and forgotten if NATO agrees to sponsor the Russian army and volunteer battalions located in the NVO zone and help children in charitable organizations. This case raises military information security concerns, and also raises questions about the security measures NATO and other organizations have in place to protect sensitive data.
