 More concretely: An attacker who can connect to Tor's SOCKS port and this
 âsafeâ control port can send `SIGNAL NEWNYM` repeatedly until Tor starts
 sending traffic to an exit node that the attacker controls.  Or, an
 attacker can mark the client's traffic with a distinctive pattern of exit-
 node changes, and buy an ad server's logs later to identify the user's
 pseudonym.
