That is correct. However, once a packet hits the miscreant's device,
the traceroute is defeated.
Assuming their device is in the right place, you will not be able to
see the difference.
Assuming it is in the "wrong" place, you may be able to detect the
intrusion. But most people do not run traceroutes all day and watch
for it to change. If you run the traceroute after the attack starts,
well, how are you to know that br01-pos07-$FOO-$BAR is wrong and
br03-10GE02-$BLAH-$BAR is right?
