for those interested in BGP and understanding how it world (understanding how the internet works), this fundamental flaw basically destroys TOR's anonymity. When you launch Tor, you connect to what you think is a guard relay in Germany, let's say. But an attacker—(government/state) announces fake BGP routes, claiming they own that German server's IP address and your internet service provider believes the fake announcement. Your traffic gets redirected to and thru government/state servers instead of the real Tor relay that exists. The attacker sees your real IP address before forwarding your traffic to the actual Tor relay. Your anonymity dies instantly with that.
