标题： SoK: A Review of Cross-Chain Bridge Hacks in 2023

摘要： 区块链技术通过实现安全和去中心化的交易，彻底改变了各个行业。 然而，区块链生态系统的孤立性阻碍了不同链之间的数字资产无缝转移。 跨链桥梁作为重要的Web3基础设施出现，以解决这一挑战，通过促进不同区块链之间的互操作性。 尽管设计复杂且有安全措施，跨链桥梁仍然容易受到各种攻击。 行业经历了桥梁攻击的激增，导致了重大财务损失。 最大的黑客攻击影响了Axie Infinity Ronin桥，损失接近6亿美元。 本文分析了2022年和2023年最近的跨链桥梁攻击，并检查了被利用的漏洞。 通过了解攻击性质和底层弱点，本文旨在提高桥梁安全性并提出潜在的对策。 研究结果有助于制定行业范围内的桥梁安全和运营弹性标准。 解决最近跨链桥梁攻击中被利用的漏洞和弱点，有助于增强对跨链互操作性的信任和信心。 显示英文摘要

摘要： Blockchain technology has revolutionized industries by enabling secure and decentralized transactions. However, the isolated nature of blockchain ecosystems hinders the seamless transfer of digital assets across different chains. Cross-chain bridges have emerged as vital web3 infrastructure to address this challenge by facilitating interoperability between distinct blockchains. Cross-chain bridges remain vulnerable to various attacks despite sophisticated designs and security measures. The industry has experienced a surge in bridge attacks, resulting in significant financial losses. The largest hack impacted Axie Infinity Ronin Bridge, with a loss of almost \$600 million USD. This paper analyzes recent cross-chain bridge hacks in 2022 and 2023 and examines the exploited vulnerabilities. By understanding the attack nature and underlying weaknesses, the paper aims to enhance bridge security and propose potential countermeasures. The findings contribute to developing industry-wide standards for bridge security and operational resilience. Addressing the vulnerabilities and weaknesses exploited in recent cross-chain bridge hacks fosters trust and confidence in cross-chain interoperability.
