Check out this new contest brewing for DEFCON 16!

From the DEFCON Forums:
The Race to Zero involves contestants being given a sample set of viruses and malcode to modify and upload through the contest portal. The portal passes the modified samples through a number of antivirus engines and determines if the sample is a known threat. The first team or individual to pass their sample past all antivirus engines undetected wins that round. Each round increases in complexity as the contest progresses.
