Skype flaw allows for collection of user IP addresses

Instructions on the site explained how a user could download a patched version of Skype that would "help you to get info about Skype user: City, Country, Internet provider and internal user IP-address."

The disclosure comes as Skype looks to move forward from its $8bn acquisition by Microsoft. Since the deal closed, the company has seen its VoIP (Voice over Internet Protocol) platform become a key component in Microsoft's enterprise communications plans.
