What is a governance attack and how can a DAO be taken over?

Understanding Governance Attacks in Decentralized Autonomous Organizations

A governance attack occurs when an individual or group exploits the decision-making mechanisms of a decentralized autonomous organization (DAO) to gain control over its operations, treasury, or policy direction. These attacks are not always technical in nature; instead, they often leverage economic incentives, token distribution imbalances, or flaws in voting systems. Since DAOs rely on token-based voting to determine outcomes, attackers can manipulate this process if they accumulate enough voting power.

1. Governance attacks typically begin with the accumulation of governance tokens, which grant holders the right to propose and vote on changes within the DAO. If a single entity amasses a significant portion of these tokens, they can unilaterally influence or even dictate decisions.

2. Some attackers exploit low voter participation by submitting proposals that appear benign but contain hidden malicious code or fund transfers. With minimal opposition due to apathy or lack of awareness, such proposals pass unnoticed until damage is done.

3. Flash loan attacks have been used in DeFi-related DAOs where attackers borrow large sums of tokens temporarily, use them to sway a vote, then repay the loan—all within a single transaction block. This allows temporary control without long-term capital investment.

4. Sybil attacks involve creating multiple fake identities to amplify voting weight. While blockchain addresses are pseudonymous, coordinated actors can control numerous wallets to simulate broad support for a proposal.

5. In some cases, core developers or early contributors retain privileged access through multi-signature wallets or admin keys, making them targets for social engineering or collusion. If compromised, these roles can override community decisions.

Methods Used to Take Over a DAO

Taking over a DAO does not require hacking smart contracts directly. Instead, attackers focus on influencing governance structures through legal but exploitative means defined by the protocol’s own rules.

1. An attacker may purchase or borrow governance tokens on secondary markets, concentrating enough voting power to push through self-serving proposals. This method relies on economic dominance rather than technical intrusion.

2. Exploiting delegation mechanisms is another common tactic. Many DAOs allow token holders to delegate their voting rights. If users blindly delegate to centralized entities or whales, those delegates can wield disproportionate influence.

4. Coordinated voting pools or bribe platforms like vote-buying markets enable third parties to incentivize voters to support specific outcomes, undermining the integrity of decentralized decision-making.

5. Forking the DAO’s codebase and syphoning liquidity from associated protocols can follow a successful takeover, allowing attackers to drain funds or redirect development toward fraudulent ends.

Real-World Examples of DAO Takeovers

Several high-profile incidents highlight how governance attacks translate into real losses and operational disruption.

1. The Beanstalk Farms exploit in 2022 demonstrated a flash loan attack where an attacker borrowed $250 million worth of assets, used them to gain voting control, passed a malicious proposal, and drained over $180 million before repaying the loan.

2. In the case of Vulcan Forged, a malicious proposal was approved due to low voter turnout, resulting in the theft of approximately $1.4 million from the project’s treasury.

3. The Fei Protocol and Rari Capital merger created TribeDAO, but poor voter engagement allowed a small group of stakeholders to later execute a contentious reversal of the merger, showcasing how fragmented communities can lose strategic direction.

4. Some projects have seen insider-led takeovers where founding teams retained excessive token allocations or admin controls, enabling unilateral decisions despite community opposition.

5. Vote manipulation via bribes has occurred on platforms integrated with decentralized governance layers, where financial incentives outweighed alignment with long-term project goals.

Common Questions About DAO Governance Attacks

What makes a DAO vulnerable to governance attacks?A DAO becomes vulnerable when there is concentrated token ownership, low voter participation, absence of timelocks on critical actions, reliance on centralized multisigs, or weak proposal validation processes. Economic centralization often poses a greater risk than technical vulnerabilities.

Can governance attacks be reversed after they happen?Reversal depends on the design of the system. Some DAOs implement timelocks that delay execution of proposals, allowing time to respond. Others may fork the protocol to restore previous states, though this creates fragmentation and trust issues among users.

How do flash loans enable governance takeovers?Flash loans allow attackers to temporarily acquire massive amounts of tokens without collateral, use them to vote in favor of a malicious proposal, execute the outcome, and repay the loan—all within one blockchain transaction. This gives them momentary control without owning the tokens long-term.

Are all governance proposals risky?Not all proposals are dangerous, but any change involving fund movement, contract upgrades, or administrative permissions requires scrutiny. Transparent discussion, formal verification, and delayed execution periods help reduce risks associated with legitimate-looking but harmful proposals.
