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 ...
I think you're going to like this video:
Last week, actor Mark Ruffalo took “the people’s microphone” at Occupy Wall Street -- not to promote a new movie, but to issue a powerful call to action. In under three minutes, Mark connects the dots between the Keystone XL tar sands pipeline, fracking, Occupy Wall Street, and the big action planned in DC for November 6th. Mark's speech captures exactly the kind of energy we'll need to win this fight.

People across the country have been feeling frustrated: frustrated with the corporate control of our democracy, frustrated with the rising levels of pollution in our atmosphere, and frustrated by the lack of a movement powerful enough to turn the tide. We are seeing that frustration reflected in the #occupy events that are growing throughout the country -- but frustration alone is not enough.
As Mark says in the video, the task ahead of us is to “turn our grief into winnable action. November 6th is a winnable action!”
The November 6th action in DC is shaping up to be a historical mobilization for this movement. As Mark describes it, "We're going to make a Human Chain around the White House -- to remind Obama to unlink his arms with the corporations, the gas and oil industry, and entwine his arms with the people that he is in charge of taking care of."
Sounds like a plan to me.
Let's do this,
