No DEF CON 25 Mystery Challenge or badge contest.
Curious Codes, the company that was designing the DEF CON 25 badges,
notified us they are no longer working on any challenges or badges for DEF
A combination of design and planning delays combined with a last minute
unforeseen personal circumstance made their production impossible.
WHAT DOES THIS MEAN FOR DEF CON?
No special badges or challenge and no mystery challenge
SO NOW WHAT?
We've gone with a DEF CON 25 anniversary theme with the badges and have
worked around the clock to get them designed and ordered. Not to fear, we

Stay tuned for more info on #badgelife, we are planning a badge meet up for
all those who enjoy building and collecting conference or contest specific
badges of all kinds.

Beardless, but interested in competing? Please know that there is a freestyle category that actively encourages the creation and display of faux, ersatz and/or fictive facial hair arrangements. Fanciful and improbable designs welcome.
