Eeeh, well, you can either 1) probe the systems yourself to make sure it
isn't doing anything it isn't supposed to, or 2) trust those of us who
claim to have done so, observing no aberrant behavior in the process. :)
There are a lot of machines that have put in a lot of hours with this
client, and no one has yet reported the clients doing anything malevolent.
This is, of course, not proof positive, but if there's something
unpleasant hidden in the binary, it hasn't reared its head yet. And if
you're really paranoid (and your machine's OS isn't a walking, talking
security hole), you can always run the program as a user that can't do any
damage if it goes wild...

Because quite frankly, the NSA doesn't *need* our help to do their
cracking. They're doing plenty of it already, much faster than we are,
they just won't admit to it. As wonderfully large (prohibitively so, our
opponents like to point out) as this effort seems, it's a drop in the
bucket compared to the processor power that a corporation (or, say, the US
government) could put together.
