co4ie Posted October 21, 2011 Report Posted October 21, 2011 (edited) Tempting, no? All that data, flowing freely in open space, back and forth to the ground — anyone with a radio should be able to pick it up and start decoding. Of course, cheapskates have been stealing satellite TV for decades. When I was a teenager, those big backyard dishes seemed to be everywhere, swiping free programming; nowadays it’s all about receiver decoding. That’s illegal, by the way, and also increasingly difficult; check out this video to see just how technical it’s become. Military satellites are simply too powerfully encrypted. That doesn’t stop people from paying very close, even obsessive attention to them: By coordinating their efforts, amateur observers in Europe, North America, and South Africa monitor satellites at different phases of their journeys and extrapolate the precise dimensions of their orbits. Astonishingly, despite the hobbyists’ modest resources – most observe part-time from their balconies and backyards with equipment available at RadioShack – they are good enough to spot almost anything the US’s National Reconnaissance Office, with its estimated $7 billion budget, blasts into space. Interested in joining that kind of fun? N2YO is a hobbyist site that lets you track satellites of all kind in real time, as they fly right over your head. Their database is impressively detailed. If you want to actually capture signals, NOAA weather satellites are the way to go. Here’s an explanation of how to grab your own imagery and decode it directly. Finally, the real frontier: hacking the downloads and uploads. “It’s like a very big Wi-Fi network that’s easy to access,” says a security expert, in Forbes: Cybersecurity researcher Leonardo Nve presented a variety of tricks for gaining access to and exploiting satellite Internet connections. Using less than $75 in tools, Nve … says that he can intercept DVB signals to get free high-speed Internet. [He] also went a step further, describing how he was able to use satellite signals to anonymize his Internet connection, gain access to private networks and even intercept satellite Internet users’ requests for Web pages and replace them with spoofed sites. And once they start messing with GPS — that’s when things will get serious. Welcome to hacking’s High Frontier.SURSANow That`s A Fucking Challenge !! Edited October 21, 2011 by co4ie 1 Quote
skipper Posted October 21, 2011 Report Posted October 21, 2011 (edited) Cam vag topicul insa acel site n2yo e foarte interesant.Nu am apucat sa il studiez,dar daca poti trimite si mie un pm cu sursa sau macar o copie a articolului.Sunt pasionat de tot ceea ce inseamna global network (GSM in special)Multumesc anticipat.PS: e o problema cu link-urile.Sunt puse aiurea Edited October 21, 2011 by skipper Quote
yo9gjx Posted October 21, 2011 Report Posted October 21, 2011 (edited) E o mare prostie, nu are nimic de a face cu securitatea. Articolul tine strict de radioamatorism. Inclusiv receptia imaginilor meteo de la NOAA. N2YO este un radioamator american de origine romana, Ciprian Sufitschi care intretine situl radioamatorilor romani www.radioamator.roPentru informatii de gen cu privire la sateliti uitati ceva link-uri:AMSAT - The Radio Amateur Satellite CorporationISS Fan Club | get in touch with the International Space StationWindows on Earth | IntroUHF-Satcom.com - The #1 online resource for VHF to EHF satellite reception and monitoringSatBeams - Home.............................................................................................si SoftOrbitronGpredictmeteo - WXtrack - predicts satellite positions and ground path images - from David Taylor, Edinburgh....................................Si acum fiti putin atenti. In domeniul SAT hacking inseamna folosirea ilegala pentru comunicatii a unor sateliti ce nu apartin radioamatorilor. Exemplu, sunt pe orbita geostationara in jur de 30.000 km altitudine sateliti militari vechi care au transpordere in aceeasi banda si au ramas nefolositi. Sunt pe ei o gramada de statii pirat si cu o investitie modesta poti sa-ti asiguri comunicarea pe mai mult de jumatate de planeta. Studiati foarte atent situl satellitenweltGasiti pe el tot ce trebuie, sateliti liberi, echipamente radio folosibile, cele mai simple antene, date despre fiecare pasare in parte etc. Satellitenwelt - UHF Militr-Satelliten im GEO, HEO und LEOAm facut niste inregistrari cu receptia piratilor din zona:Hamradiotube - PiratesHamradiotube - UFO - 255.550 Mhz....etcCine vrea detalii despre domeniu - PMrevin cu un edit, o pagina frumoasa desi veche cu aselenizareahttp://wechoosethemoon.org/# Edited October 21, 2011 by yo9gjx 2 Quote
