I just received an email from another listserv today, and thought of the blog post I wrote here a while back. Here's the email I received and I'll comment more below:

Thought I'd warn you of a thing that's apparently going around in Skype.
I had my Skype account hijacked, The hijacker changed my password and email
address that was associated with my account so I could not get into the
account again myself.
Then they placed phone calls and charged the credit card that's on file for
autobill with Skype.
It apparently started when I received a file attachment from a known
business contact that looked like an image file but wouldn't open after I
downloaded it.
Skype customer service helped me out with it, but it's a pain. Be careful
with attachments – even if they come from trusted sources! If you don't know
what is being sent, confirm via text message before downloading anything!

I had the same thing happen to me with Chat rooms, where I would be in the room and receive messages from someone else who was posing as ME, teasing ME about SECURITY while I was talking to my world-wide programming staff. That made me shy away from even thinking about using chat rooms with patients.
