Helping people with computers... one answer at a time.
Someone sniffing a Skype conversation would just find digital noise. But I guess it depends on... how paranoid are you?
I'm using a laptop with Windows 7, 64-bit installed on it. Also, ESET Internet Security is fully up to date on it. I use a D-Link wireless router to connect to the internet with security key protected. Windows Firewall is not on, as recommended by the default. I use Skype to talk to my friend. How do I make sure that nobody sees or listens to us? Also, under the given circumstances, what is the possibility that I'm seen or heard by a third person?
In this excerpt from Answercast #44, I look at the issue of privacy on Skype conversations.
So, as I understand it, and this is only my understanding – I have to throw that caveat out there (it's very possible I could be wrong, but I don't think that I am):
My understanding is that Skype conversations are encrypted from end-to-end.
In other words, if I'm talking to you over a Skype conversation, there's nobody in the middle that can listen. All they can see is encrypted data, which is digital noise.
Now, there's been some recent concern (with Microsoft's acquisition of Skype last year and some of the architectural changes that they announced recently):
That maybe... maybe...Microsoft (or Skype itself) has the ability to intercept phone conversations or Skype conversations on their servers, in-between you and the person you're talking to.
They have indicated that they are apparently able to intercept or look at text messages:
If you're IMing using Skype, I believe that may be visible.
I don't know the implications on voice.
Now, this is where it starts to dive into the area of, "Just how paranoid are you?" How concerned are you about this kind of thing?
My thinking along these lines is always this:
You know what? You and I are just not that interesting!
Nobody at Microsoft, nobody at Skype is going to sit there listening in to your conversation - or my conversation.
There's just nothing in it for them.
On the other hand, if you're paranoid... if you're really talking about something that (I don't know) threatens national security, then yes, Skype might not be the best option. There are other options out there. Skype may just not be the one.
But like I said, right now my sense is that no, certainly no arbitrary person is going to be listening in on your conversations; no, certainly our ISP isn't going to be able to – those kinds of things.
It's going to be either you at your end, the person at the other end, maybe,
(maybe...) there's a remote possibility that Skype in the middle could listen
in. But again, I really don't see a reason and I'm not even sure that actually
