[TriLUG] cable modem caps locally

[Ryan Leathers]

A couple months back securityfocus ran a story on a kid out west who was
being prosecuted after running a cap hack tool.
As I recall the tool basically spoofed the provider tftp server and
pushed a crafted config onto the modem with a much higher cap.
The kid was claiming ignorance and his lawyer was trying to blame the
writers of the tool and the cable provider.
I didn't pay enough attention to see what happened to him.

Food for thought.

Its definitely capped locally on the cable modem. Whether or not its
also capped at the concentrators is anyone's guess.

If I say too much more, I violate federal law.
