Poco meno di mille dollari: con questa cifra un team di ricerca è riuscito a raccogliere, per anni, traffico satellitare geostazionario non cifrato . È una cifra bassa — e questo è il punto: la vulnerabilità non risiede in hardware esoterico ma in pratiche di configurazione e in assunzioni sbagliate sull’obscurity del mezzo. Come hanno fatto Il principio è semplice: molte stazioni geostazionarie trasmettono segnali che coprono vaste porzioni di superficie; un’antenna direzionale, anche piccola, orientata correttamente riesce a ricevere quei segnali. I ricercatori hanno usato un setup economico, software-defined radio e tool open-source per decodificare e analizzare flussi IP e VoIP. L’operazione è passiva: non si inviano pacchetti né si interferisce — si ascolta. Perché questo è rilevante? Perché la trasmissione on-air non cifrata rimane leggibile a chiunque abbia l’antenna. Non c’è bisogno di attacchi sofisticati o di accessi privilegiati: basta la linea di vista e il know-how ...
Poland has officially recognized the trading and mining of virtual currencies as an ‘official economic activity’ according to the Central Statistical Office of Poland, hereinafter GUS. GUS is Poland’s executive agency dealing with national statistics and reports directly to the Polish Prime Minister’s office.

Companies that are active in this area will be able to gain an official PKD 64.19.Z registration.

The position of Bitcoin in Poland has been undergoing a sea change, while way back in 2013 there were reports of an official from Polish Ministry of Finance as saying, “What is not forbidden is permitted. However, we certainly cannot consider Bitcoin to be a legal currency.”
Then in September 2015, the Polish Finance Ministry issued a statement to the effect, “Any regulatory action addressing the problems of trading virtual currencies.They should be taken either as a result of initiatives at the EU level with a view to the cross-border nature of the business or as a result of a threat market failure cryptocurrency.”
Poland has been one of those countries that want to tax Bitcoin profits and the unclear status of Bitcoin in Poland has been a source of anxiety as banks in Poland have moved to close accounts of clients trading in Bitcoin.
It would be interesting to see if Bitcoin can be accepted as a currency in Poland or throughout Europe as it has already been in Japan, for example.
