Critical Flaw in Tor Browser Reveals Real IP Address

November 6, 2017

For those of us that visit the Dark Web (most users should stay away from it), a critical flaw has been disclosed in the Tor browser. The Tor browser is used to navigate the Dark Web and "bounces" traffic around several nodes, relaying data packets before ending at the destination node. This path of relays is used to mask the real originating IP of the requesting node. The bad news is that a critical flaw has been discovered for Mac and Linux users of the Tor browser that reveals the real IP address of your machine. The flaw does not impact Windows or Tail users. The Tor Project issued a workaround that plugs the IP leak. Mac and Linux users should update their Tor browsers immediately until a permanent fix is available.
