SoK:针对 DAO 的攻击

SoK: Attacks on DAOs

Rainer Feichtinger, Robin Fritsch, Lioba Heimbach, Yann Vonlanthen, Roger Wattenhofer

AI总结:

本文系统梳理 DAO 面临的现实、理论与审计中发现的潜在攻击,将攻击向量归纳为四类,指出审计偏重代码漏洞而忽视治理中的人性风险,并提出缓解策略。

摘要:

去中心化自治组织(DAO)是基于区块链的组织,旨在促进去中心化治理。如今,DAO 不仅在其金库中持有数十亿美元资产,还治理着许多最流行的去中心化金融(DeFi)协议。本文系统分析了 DAO 面临的安全威胁,重点关注其所遭受的攻击类型。我们研究了过去实际发生的 DAO 攻击、理论上被认为可能发生的攻击,以及在审计中发现并阻止的潜在攻击。针对每一种(潜在的)攻击,我们描述并归类其所利用的攻击向量,将其划分为四个类别。分析表明,虽然许多针对 DAO 的攻击利用了治理中较不具象且更复杂的人性因素,但审计往往侧重于代码和协议漏洞。因此,本文进一步考察了 DAO 漏洞的经验数据,概述了导致这些攻击的风险因素,并提出了防范此类漏洞的缓解策略。

英文摘要:

Decentralized Autonomous Organizations (DAOs) are blockchain-based organizations that facilitate decentralized governance. Today, DAOs not only hold billions of dollars in their treasury but also govern many of the most popular Decentralized Finance (DeFi) protocols. This paper systematically analyses security threats to DAOs, focusing on the types of attacks they face. We study attacks on DAOs that took place in the past, attacks that have been theorized to be possible, and potential attacks that were uncovered and prevented in audits. For each of these (potential) attacks, we describe and categorize the attack vectors utilized into four categories. This reveals that while many attacks on DAOs take advantage of the less tangible and more complex human nature involved in governance, audits tend to focus on code and protocol vulnerabilities. Thus, additionally, the paper examines empirical data on DAO vulnerabilities, outlines risk factors contributing to these attacks, and suggests mitigation strategies to safeguard against such vulnerabilities.
