Security Alert: Using a chain contract polling mechanism may have security risks

At 7:30 this morning, Chengdu’s chain-state situational awareness system Hawkeye issued an early warning on a game contract transaction. Our security personnel analyzed the warning and found that the attacker is using a new way to obtain random number seeds and pass the contract. Constantly initiate delay transactions, try to pre-calculate or get the lottery parameters of the game contract, the security team has notified the project party to confirm, and suggest that the project party with similar online-based contract timing lottery mode should check in time to avoid losses.
