Researchers Can ID Anonymous Twitterers

narramissic writes "In a paper set to be delivered at an upcoming security conference, University of Texas at Austin researchers showed how they were able to identify people who were on public social networks such as Twitter and Flickr by mapping out the connections surrounding their network of friends. From the ITworld article: 'Web site operators often share data about users with partners and advertisers after stripping it of any personally identifiable information such as names, addresses or birth dates. Arvind Narayanan and fellow researcher Vitaly Shmatikov found that by analyzing these 'anonymized' data sets, they could identify Flickr users who were also on Twitter about two-thirds of the time, depending on how much information they have to work with.'"

Any IP address that has been assigned to me by a corporation that ALSO possess my name, address, social security number, telephone number, etc. has never been recorded by the destination. I am sure that plenty of TOR nodes and proxy's have that IP address, but I am reasonably sure of the difficulty of obtaining that information. Which is why I usually like to connect for anything interesting through other machines that I control first on networks that I can be reasonably certain are not logging IP address information, or that I am connecting to with wireless.

      Do you use Flash, Java, or any other plugins that potentially give away identifying data?

      When I do, it is on a virtual machine that is locked down with no information inside of it and just as easily destroyed afterwards. As for preventing that machine from learning the public IP address it communicates on, that is pretty damn easy for me (difficult for the machine) since all traffic is routed through TOR, and not a TOR that is installed on it. TOR someplace else on the network. Those virtual machines have literally no other routes outside the network except for TOR. They cannot even communicate with the host.

      Until somebody actually pulls of a hack in which their malware can be "Virtual machine aware" and compromise the hosts through the guests, I can be reasonably certain of the hosts safety.

      Does your browser leave any data that you are unaware of?

      Most likely. However, it is unlikely that survives when the entire virtual machine is destroyed upon exiting. Every new session has no access to any data that was recorded in a previous session. That includes all cookies, flash cookies, or anything else that I am simply unaware of.

      What about your operating system?

      I never use a host operating system to do much of anything, especially anything that connects to a remote network. All of that is virtual now and destroyed afterwards when appropriate. Of course any machine that is used for gaming has a more direct connection, but they are on a separate network and I am not so much concerned about Steam, XBOX Live, etc. I don't give any information on those networks which could be used to form conclusions about relationships outside of "entertainment networks".

    Long story short: If you don't clear your cookies AND use a proxy, and you post anonymously in a bitch-slapped thread or get individually bitch-slapped by a moderator or your logged in username is associated with a bitch slapped or habitual troll IP you will never moderate again and be on $rtbl.

    Now my high-karma account no longer can moderate, it can meta moderate but no longer moderate. This $rtbl is hardly real time. Its a permanent ban.
