I'm very well aware of Brazil's economic status as a country. I wasn't seeking to comment on the country as a whole, simply the segment of the population hijacking signals. I stand by my statement that this segment of the population has very little resources in the grand scheme of technical attacks. Seems as if you were looking for something that wasn't there.

Believe if I say the Brazilians who are doing this are not "impoverished". They just found a freebie and many of them don't even know they shouldn't do it.

As for the military implications, I don't know why the hell those birds were not DoS'ed before. If a couple clever civilians figured that out, I can't believe no bad guy ever tried that.

How effective a DoS on those satellites would be on denying US-Navy fleetwide communications?

Actually, I assume badguys are already using those satellites for short bursts of encrypted data that looks an awful lot like navy traffic sent via very narrow beams the satellite (and ground people) have no hope of finding where it came from.

Perhaps, instead of cracking down, the Navy should call the NSA and listen more carefully to what is being transmitted.

I dunno, you don't have to be Wozniak to use a blue box...
