EOSDice gambling platform was attacked in November 2018 via exploitation of its controlled-seed randomness flaw. Attackers predicted the random number generation by analyzing blockchain state information. EOSDice was one of eight EOS DApps targeted simultaneously in coordinated randomness attacks.

The well-known DApp EOSDice was hacked again due to random number issues. The attacker was a hacker who previously attacked EOSDice and FFGame DApp. The project side wrongly add a controlled seed in random algorithm which lead the attack.
