[Full-disclosure] Sasser or other nasty worm needed

[kikazz]

I'm a high school network administration teacher looking for a creative
means of teaching my students the importance of patch management.  I was
hoping to let a particularly nasty worm loose on a closed lab so my students
could see what happens during an outbreak, but I'm running into a hitch - I
can't find a worm that would spread quickly enough to be useful.  

Does anyone have a copy of Sasser or a similar worm that they would be
willing to send or link me to?  Please contact me off-list.  I would be
happy to verify my identity as a high school teacher off-list as I'm sure
that is a concern for most anyone who has what I am looking for.  

Please do not reply on list as I am not currently a member.  

Thank you,

Chris
