Scallion/cathugger attack on Tor
A used scallion to search public key for "abcde*", and got "abcdeyyyyyyyyy.onion" A used it to host his website
B want to takedown A. B used scallion to search public key for "abcde*", and got "abcdeyyyyyyyyy.onion"
This is a possible attack of Tor's hidden service. Unfortunately, V3 onion namesystem are already cracked: github.com/cathugger/mkp224o
What can you do to stop this from happening? How can I block other people from generating my onion's hidden key?
Why not add a protection? "If 2nd connection tried to connect with known hostname(B), deny it and raise error."
