Re: Skype vulnerability or feature

Hi,

I was fiddling a little bit with Skype when I discovered that I could
login at the same time from two different terminals unlike other
messengers such as MSN. In such a scenario if someone gets hold of
your skype identity you would never know and he might just successfuly
abuse your account again and again.

Other things that I noticed were that an attacker would be able to
accept calls directed to the authentic user. For e.g. the ring comes
on both the terminals the user who accepts the call first get access
while the second one gets missed call notification.

Or they are both authentic. It's one of the things I like about Skype. Some of us have more than one computer. This makes it possible to leave Skype running on say a workstation at home, and have it running on our laptop when we duck out for a coffee.

-Kurt
