Okay, so in the last week alone, I've had four friends that have had their Skype accounts hacked.
A message will be sent to me from a friend's account that contains a goo.gl link with a person's username attached. I have a habit of ASKING before clicking links that are sent to me out of nowhere (usually sent by people I haven't talked to in a while) so instead, I immediately will question what the link is, and every time I've been told someone hacked their account and the link is a virus. So if you get a message from a someone on skype and the the message is nothing but a goo.gl link that has your username in it, DO NOT CLICK IT. Instead, check with the person that sent it and tell them their account has been hacked.
As of yet, I haven't been hacked (or at least I haven't been told I have), but if you get a similar link from me, please let me know.
