TeamOneFist claim to have attacked russian Satelite

One of the spokesmen for the pro-Ukraine hacktivist group TeamOneFist claimed responsibility for a major attack on the Russian satellite network "Gonets" during the "Pleiades" cyberoperation. The attack would have disabled the satellite network. 

He claims to have penetrated the CRM/customer database, which is referenced by the network in order to send/receive messages. Having failed to download the database, which was under heavy surveillance, the group decided to destroy it without being detected. 

From this data, the group discovered that the Gonets network was used by 97 organizations to transmit sensitive data, including fishing companies, energy companies and the FSB.
