#CHES Challenge 2016 Wraps up - Emails going out now searching for "best student", please be on lookup for it!
Ability to submit flags being disabled in 20 mins!
"USB Error" on virtual HW lab appears to be pack - hold on will fix shortly here!
Still 4 days left to submit an implementation, the virtual HW lab will be turned off on July 31st @ 15:00 UTC!
FIX: Issue with "USB Error" has been fixed (I think)
NEW FLAG NOTE: Server still having issues fully validating PT/CT enc pairs, appears latest flag as ~5% error rate so watch out!
**ERROR WITH LATEST FLAG** - Appears to be invalid responses, I think the flag will have to be scrapped & a new one uploaded.
FIXED: Scores will be audited tomorrow to confirm, but should be fixed. Also ignore the "New Flag Submitted" email, was artifact of fixing.
TO FIX: Scoring had errors again due to stage gates being given 30 pts! That will be fixed, scores will finally be accurate, sorry!
SCORING: Updated to reflect correct 2nd-place captures per rules. Biggest adjustment to "OverTime" with +30 points.
