It can also collect data. from a data form address that has not yet passed through the Blockchain – that is, the BTC address provided in the part of a kidnapping or life-threatening investigation – if the suspect verifies his address.
Neither the date of the presentation nor the time of the creation of the materials is currently available. The original leak involved a cache of documents allegedly obtained from the dark web team of Nucleo Speciale Frodi Tecnologiche de la Guardia Di Finanza.
