Ne’er-do-wells have long abused a feature in Skype to glean the Internet address of other users. Indeed, many shady online services that can be hired to launch attacks aimed at knocking users offline bundle so-called “Skype resolvers” that let customers find a target’s last known location online. At long last, Microsoft says its latest version of Skype will hide user Internet addresses by default.
A few months ago, I warned readers that a glaring privacy weakness in voice-over-IP telephony service Skype allows anyone using the network to quickly learn the Internet address of any other Skype user. A new beta version of the popular Microsoft program appears to have nixed that privacy leak with a setting that restricts this capability to connections in your Skype contacts only.
The events of the past week reminded me of a privacy topic I’ve been meaning to revisit: That voice-over-IP telephony service Skype constantly exposes your Internet address to the entire world, and that there are now numerous free and commercial tools that can be used to link Skype user account names to numeric Internet addresses.
