A new security vulnerability in Skype has been discovered that allows a third-party script to reveal users’ remote and local IP addresses, according to GHacks. The script, which was uploaded to Github, allows users to lookup the IP addresses of any online Skype accounts. The code then initiates the contact addition process, but does not complete it. The log file will instead display the local and remote IP of the requested Skype user, even if the user is not added to the list of contacts. An IP address can be used to determine the location and Internet service provider of the user, and the only method of protecting against this vulnerability would be to use a virtual private network or proxy to hide the IP address.
