| Promiscuous mode can also be enabled on most hardware routers. A

| traffic passing through the router as well as insert packets. This
| is major security leak and one that spoofers look for.
I am curious, how do you do that? From what I understand, a promiscous
mode allows someone on the box to see all packets that hit the
interface. How does it allow an attacker (outside the box) to sniff
packets hitting that interface?
