The table below shows the time that each encrypted challenge file was first cracked, and the first eligible team to crack it (limit of six per team). These results are going to be manually verified; unlike the above, they are not final. There is a side-prize of a $65 donation to EFF or Child's play for being the first to crack challenge file.
