Cetus, a trading platform on the Sui blockchain, has suffered a loss of $223 million in a major hack that occurred on 22nd May. In a recent report, the firm has revealed that the hack occurred because of a hidden mistake in a piece of open-source code that the firm used for its smart contract. This inaccuracy of the firm has made its security system weak, and hackers were able to steal the money.
The firm admitted its mistake. It stated that the flaw in the code allowed hackers to steal funds. The incident has raised concerns, highlighting how risky it can be to use outside code in DeFi projects.
The hack has also impacted the value of tokens on the Sui blockchain, as it started to drop quickly. As per the reports, after the hack, Cetus and the Sui network’s validators quickly stepped in to stop more money from being stolen by refusing to validate transactions signed by the attacker’s address.
However, attackers had already converted $60 million into different forms and removed it from the blockchain, making its recovery challenging. To help recover the money, Cetus offered a $6 million reward for its return and promised to improve its security by doing stricter checks and better monitoring.
The hack led to significant disagreements within the crypto community. Some people in the community have praised the firm for taking action quickly, and on the other hand, other people were upset by it. They stated that the firm did not pay them back enough.
The firm’s users also said that the firm has not shared enough information with them. Some people have also argued about whether blockchains are decentralized or not. The freezing of funds by Sui validators demonstrates a centralized approach, which contradicts the concept of decentralization.Â
This incident highlights that DeFi projects like Cetus will have to be much more careful. They have to double-check their code to avoid mistakes that hackers can use, and they need better rules to keep things safe, to make their users trust them again, and to avoid hacks in the future.
