Global Blockchain Ecosystem Security Analysis for Q3 2022: Losses Reached 400 Million USD

The blockchain industry encountered several significant security incidents in the third quarter of 2022, resulting in total losses of approximately $405 million. Although the number of attack incidents decreased compared to the previous quarter, the amount of loss remained substantial, highlighting the severity of blockchain security issues.

Analysis of Major Attack Events

During this quarter, there were more than 37 major attack incidents, with the most severe loss being the $190 million attack on the Nomad cross-chain bridge. This was followed by the $160 million attack on the Wintermute trading platform, and the $56 million attack on the BSC Token Hub cross-chain bridge. These incidents highlight that cross-chain bridges and centralized trading platforms have become primary targets for hacker attacks.

Attack Trend Analysis

Compared to the previous quarter, the number of attack incidents has decreased this quarter. There were 14 major attack incidents in July, followed by 12 and 11 incidents in August and September, respectively. This downward trend may be related to the overall market downturn, but it does not indicate a weakening of security threats.

Loss Distribution

Among all types of attacked projects, cross-chain bridges and DeFi projects suffered the most severe losses, accounting for 92% of the total loss amount. Among them, cross-chain bridge projects lost approximately $246 million, while DeFi projects lost about $126 million. This data indicates that these two types of projects remain key targets for hacker attacks and urgently need to enhance security measures.

Blockchain Network Security Analysis

The Ethereum network remains the most attacked Blockchain, with losses amounting to 374.28 million USD, accounting for 92% of total losses. This phenomenon is closely related to Ethereum's status as the primary smart contract platform and reflects the significant security challenges it faces.

Attack Method Analysis

Among all the attack methods, contract vulnerabilities and private key leaks are the main causes of losses, accounting for 92% of the total loss amount. The losses caused by contract vulnerabilities amount to approximately $226 million, while the losses due to private key leaks are about $146 million. This indicates that the security of smart contracts and private key management remain critical issues in Blockchain security.

Capital Flow Analysis

Among the illicit funds obtained by attackers, approximately $240 million flowed into mixing services such as Tornado Cash. This phenomenon has raised concerns about the potential misuse of privacy tools, while also highlighting the difficulties in tracking and recovering stolen funds.

Security Audit Status

It is concerning that only 40% of the attacked projects have undergone security audits. This data indicates that most projects did not undergo adequate security checks before going live, which undoubtedly increases the risk of being attacked.

Summary and Outlook

The blockchain security situation in the third quarter of 2022 remains severe. Although the number of attack incidents has decreased, the amount of loss caused by each attack is still significant. Cross-chain bridges and DeFi projects are still high-risk areas, and the security challenges faced by the Ethereum network are particularly prominent. Contract vulnerabilities and private key management are still urgent core issues that need to be addressed.

In the future, blockchain projects should pay more attention to security audits, strengthen the security of smart contracts, and improve private key management mechanisms. At the same time, the industry needs to develop more effective fund tracking and recovery mechanisms to cope with increasingly complex attack methods. Only by continuously raising security awareness and improving protection measures can we safeguard the healthy development of the blockchain ecosystem.
