[AusNOG] Optus Hack

[karen at iamunique.net.au]

Michael, I like your suggestion about hashed versions. It would have 
certainly saved some hassle.

For the last year and a half I have been working as a tutor in 
information security and at this point, would like to thank the nice 
folk at optus for allowing us to update some notes with a really good 
example of what NOT to do. I get that we went through this period where 
the terrorists would buy phones so we all had to be able to be tracked 
to prove we weren't one. But that was during a time when the value was 
in credit card information, not identify information. The public expects 
a certain level of professionalism and care to be taken with personal 
and sensitive information and especially with our identity information. 
For them to make the mistakes they have, in this day and age is just.... 
  wrong.
