Analysis of Global Blockchain Security Trends in Q3 2022

The blockchain industry experienced multiple security incidents in the third quarter of 2022, resulting in significant losses. According to statistics, there were more than 37 major attack incidents in this quarter, with a total loss amounting to approximately $450.4 million.

Compared to the previous quarter, the number of attack incidents has decreased this quarter. However, the amount of losses remains high, with 92% of the losses coming from cross-chain bridges and DeFi projects. This highlights the significant security challenges faced by these two types of projects.

From the perspective of the attacked Blockchain platform, the losses suffered by Ethereum are the most severe, reaching up to $374.28 million. This figure accounts for the vast majority of total losses, reflecting the scale and complexity of the Ethereum ecosystem, while also exposing the security risks it faces.

In terms of attack methods, 92% of the loss amount comes from contract vulnerabilities and private key leaks. This indicates that the security of smart contracts and private key management are still areas that blockchain projects need to focus on.

It is worth noting that approximately $240 million of stolen funds have flowed into mixing services. This highlights the difficulty of tracking and recovering stolen funds and has sparked discussions on the regulation of such services.

Another concerning finding is that only 40% of the attacked projects had undergone security audits. This data indicates that many projects have deficiencies in security protection, highlighting the importance of security audits.

In summary, the blockchain security situation in the third quarter of 2022 remains severe. Cross-chain bridges and DeFi projects have become the primary targets of attacks, and contract vulnerabilities and private key management issues continue to pose the greatest security risks. To enhance the overall security level of the industry, project teams need to pay more attention to security audits, strengthen private key management, and continuously improve contract code. At the same time, users should also raise their security awareness and cautiously participate in various blockchain projects.
