For diehard DefCon attendees, they are more precious than gold, diamonds and all that glitter: uber badges, a prize that gives the recipient free access to DefCon for life. On the last day of the conference each year, they are given to the top winners of various hacking contests. Or, if you have at least $500 to spare, you can get one off eBay.

A few observant infosec friends eagerly flagged the listing on Facebook this morning. Here are the details, as posted on eBay by Hackers for Charity, a non-profit organization that uses the skills of volunteer technology experts to solve challenges for various non-profits and provides food, equipment, job training, computer education and coordination of these activities for the worlds poorest citizens:

This auction is for one (1) DEFCON 17 Über Badge.  

Hackers for Charity received a DEFCON 17 Über Badge as a donation.  
This unique donation provides a creative way to raise money for Hackers for Charity. 

We are auctioning this one (1) DefCon 17 Über Badge so that the auction ends the night before DEFCON.  

YOU, the winner, can wear use this badge for entry into DEFCON 20.  We will coordinate with the winner so that Johnny Long can meet him/her Friday and pick up their Über Badge.

Additionally, as with any Über Badge, you are granted free attendance to DEFCON ... for life.

That's right. Never stand in the registration line ever AGAIN!

Due to eBay's new charity policies and grant program, 100%, yes ALL, of the proceeds go to Hackers for Charity.
