Primedice Bitcoin Gambling Site Hacked for $1M

Primedice, one of the biggest bitcoin gambling sites, has suffered a loss of $1 million when one of its members figured out a way to game the system. The user went under the name ‘Hufflepuff’ and was able to device a method to hack the dice roll game that allows people to win bitcoin.
According to the company’s CEO, they are offering rewards to anyone with information that can help them recover the lost money. The company had actually been able to figure out that ‘Hufflepuff’ has been gaming the system but the user declined to return the funds.

Primedice’s system operates by having the random numbers generated through the use of two seeds, a server seed and the client seed. Users can change and verify seeds used by clicking the ‘Rerandomize’ tab and before the user specifies their own seed, they are shown the SHA256 hash of the server seed that will be used alongside whichever seed they pick.
