Published: May 3, 2012 Reading time: 1 min

The current versions of the Tor Browser Bundle (TBB) include a bug that makes it possible for information about visited web sites to leak out of the anonymising layer. On version 2.2.35-9 of TBB for Windows and version 2.2.35-10 for Mac OS X and Linux, the included version of Firefox does not send DNS requests over the Tor network if the browser is using the WebSocket protocol.

Skype divulges user IP addresses

Published: April 30, 2012 Reading time: 2 min

The H-Online: According to a blog post, a modified version of the Skype VoIP software can be used to easily find out the IP address of any valid Skype user. No contact has to be made with the user in order to get the information. This IP could then be used to find out other personal details about the user, such as their location or even their employer. With a certain registry key, the manipulated version of Skype will create a log file with information including other users’ external and internal IP addresses. These IPs can be retrieved simply by opening up a user’s profile with the Skype client. In a test conducted by The H’s associates at heise Security, the log file always showed the correct IPs – and when a user was logged in with multiple clients, the IP addresses for all the clients were visible. ...
