The Diffie-Hellman implementation of Tor fails to verify the
|
||
|
|
cryptographic strength of keys which are used during handshakes.

|
By setting up a malicious Tor server and enticing users to use
|
||
|
|
this server as first hop, a remote attacker could read and modify all
|
||
|
|
traffic of the user.
