Re: [liberationtech] Exactly how are satellite transmissions tapped/intercepted, in Syria and elsewhere?

Of course its scary, so is being an activist and a revolutionary. Please understand that is not meant to be flip, however I find that the most important aspect of any tool or guide is to create informed consent, which means being as clear and upfront as possible about potential risks and the reality regarding what can be done to create a "best case/worst case" as well as producing an accurate threat model. I feel that too often people in a position to help refuse to provide knowledge because they would feel bad if someone got killed doing something that put them at risk, rather than asking how many people will get killed without providing access to better knowledge. The question I have is what is the method for intercepting the SMS or email sent by any specific Satphone, I'm assuming you can use radio frequency triangulation to get the data, and will need another tool to extract the SMS or email content.
OK, but: #1 this is operating on thuraya frequencies yes, so won't it still be subject to triangulation? #2 i will certainly look into the possibility for acquisition of this item, but its definitely not going to be anywhere near as accessible as inmarsat, iridium, or thuraya phones, which brings me back to my core point, since activists will definitely continue to use these devices, and the barrier to access for other tools is still so high, there is a need for clear, concise, accessible documentation about the best/worst case scenarios for these devices.
Oh I'm quite aware they will make me ill, that's why I brought the questions to this list, to get some of the best "worst-case scenario input" I could find. I was asked to help with this, though I'm fairly certain its a somewhat impossible job. As you've noted repeatedly, satellite communications are not safe by any estimation, its the proprietary hardware and many other things that are involved in these issues.
Thanks, thats great information and very helpful given the circumstances individuals in Syria are working with, however still not applicable to "majority access" however it is definitely worth it to begin raising awareness about the existence of this tool! I'm assuming it roams automatically but as with all satellite devices only works with a strong line of sight at the proper angle? cheers Brian
All the best, Jake
