Original description
It is Friday the 13th at Camp Crystal Lake. The security guard fled, but not before locking the master override code inside a digital vault (Sector 12 of this tag).
A bloody post-it note was found nearby with this cryptic binary sequence:10110101 10100010 11000001 11011001 11100100 11110000
Can you derive the secret key and extract the flag from the forbidden sector?
