I can't believe they even posted that nonsense on Cryptome. Urgent!!! Someone who roots you can disable your firewall!!! Someone who roots you can force Tor to use their entry guard and get your IP address that way. Tails really isn't designed to strongly protect you from hackers getting your real IP address if they hack you, especially not if they root you. Pretty much the only way to protect your IP address from someone who roots you, is to have Tor running on a separate machine (or the host, if you are using a virtual machine) and forcing all of your traffic through that machines Tor (or Tor on the host), and only having an internal IP address assigned to the non-Tor machine.
