Is there a way to check whether LittleSnitch is sending my private data to some bad dude?

"You can always use Network Monitor Sidekick to check on outbound and inbound traffic. Essentially, whatever goes out is allowed by LittleSnitch. Identifying the nature of the data and resolving the destination IP addresses is another matter altogether.

However, I would just like to add this: If you are really worried LittleSnitch has been corrupted, etc, why not just delete the app, along with its preferences, etc, and re-download and install fresh from the web itself?"

"Let me mention that even Little Snitch (or your firewall program) is not capable of faking a server for HTTPS connections (because your browser or OCSP has the certain chain). So whatever data they could manage to send to a bad dude are useless even, because the bad dude doesn't have the server certificate.

This leads to my next question, which is: can a Firefox extension make fake certificates show up as good? I doubt it. But a hacked firefox... hmmm... that could be a worry-point.

Anyway, of course the answer is a network sniffer, but it'd have to be on another computer to be sure that the bad dudes at Little Snitch (ironically, the only software a software pirate actually has to buy) haven't thought about your sniffer too :)"
