Re: Your Jetstream/ADSL connection is NOT secure

I complained to IHUG about this.. (I got a few copies myself (not for my
DSL connection))

Basically the IHUG customer ported scanned alot of DSL users for port 80
to see what was there (against IHUG's AUP), then gained access to the
routers which where open and got the customers login details (this can
be seem as forgery/intrusion). and then offered to fix the problem and
warned not to tell anyone else including the media of his little email
or other people will find out (isn't this called extortian). Then
offering to fix the problem for a sum of money that any ISP will help
out for free.

I think personally that what this person did was wrong

Also note, I got a customer who got this email and there was no way to
get into their router at all from remotely. ( I and another knowldgeable
person checked)

The main problem I see was basically the Modem manufactures NOT giving
good enough instruction on how to set up their routers correctly.
A good example is alot of routers I know, If you reset them back to
defaults and follow the specific NZ instructions given with them your
router is basically open to anyone to get into.

If anything, if you haven't already, please change the admin password on
your router (I'm not talking about Telecom Rented ones, as your not
allowed to touch those and they are perfectly well set up and secure) to
something no one else can guess.

Thanks
