On April 28, a serious vulnerability occurred in the smart contract code of the DeFi project Uranium Finance, and the attacker took away $50 million.

Under traditional conditions, hackers mainly rely on their advantages in computer technology when attacking the financial system, but in the existing DeFi ecosystem, due to the interoperability between chains and applications is not so good , so the probability of arbitrage between cross-chains and cross-applications may be greater. At this time, even a person with not so strong computer skills can become a hacker and attack the DeFi system as long as he has enough financial knowledge and enough market sense.

In addition, with the vigorous development of DeFi, the opening of assets (the smooth internal transfer path) is also expanding rapidly, which requires cross-chain assistance, but there are also hidden risks, that is, hackers quickly transfer assets from one chain to another , increasing the time and space cost and difficulty of tracking stolen assets.

PeckShield recommends that investors do due diligence before participating in DeFi projects, such as inquiring and verifying whether the project has undergone a comprehensive and professional security audit, and try not to participate in projects that have not passed any security audits. When it comes to safety audit projects, we should not relax our vigilance, and we need to be rational at all times.
