The place to attack is the up-link. This requires physical access (ie a van
with a dish and xmtr.) as well as a means to crack the encryption on the
control channels. At least one French satellite has been cracked and
de-orbited via a network attack.

The communications are not only documented but easily observable with the
correct commercialy available equipment. The frequencies are a matter of
public record, I would further bet that 5 minutes with a search engine would
bring that data to light...
