Distributed ledger technology, or DLT, has gained popularity as a result of blockchain’s numerous recent applications. Since blockchain is regarded as the foundation of cryptocurrency, it has produced products with a variety of uses. With NFTs, dApps, DeFi, and smart contracts, it has promoted decentralization.
The rise of DAOs has provided hard evidence of the enormous potential of blockchain technology. Decentralized autonomous organizations, or DAOs, have changed recently. This article provides a concise overview of Crypto Attacks on DAOs and how to protect yourself from them.
DAO Governance Model
Following the introduction of the blockchain, users found it difficult to embrace the new governance models because multiple parties were engaged. Nevertheless, the goal of blockchain technology was to isolate consumers from any central authority. It became necessary at this stage to create governance clarity.
A DAO’s members control its governance, using a voting method to choose how the organization should run and distribute its resources.
Members of a DAO usually possess tokens that represent their ownership share in the company and provide them the ability to vote on proposals. Members are free to join and leave at any time by purchasing and selling these tokens on the open market.
Proposals for governance may be made for a number of reasons, such as modernizing the chain or making important choices for its future. Proposals are submitted by DAO members, and the full membership votes on them.
The organization’s smart contract automatically puts a proposition into effect if a quorum of members votes in favor of it.
Crypto Governance Attacks
When an attacker exploits weaknesses in the DAO’s governance structure to gain control and make choices that benefit the attacker at the expense of other members, this is known as a governance attack.
There are numerous variations of this kind of attack. However, it typically entails the attacker controlling the organization’s decision-making process and altering its rules to their advantage by using their voting power or other tools.
Types of Governance Attacks in DAOs
1. Majority Attack
When an attacker controls the majority of the voting power in a decentralized autonomous organization (DAO), it is referred to as a majority attack.
With this level of authority, the attacker can provide the DAO with any proposal that would profit them at the expense of other members.
2. Sybil Attack
A Sybil attack involves the attacker creating numerous fictitious identities, or “Sybils,” that they can use to cast multiple votes in the DAO’s decision-making process.
Even if they do not possess the majority of the tokens, the attacker can gain substantial power within the company by creating a large number of Sybils.
3. Frontrunning
An attacker could be able to see a proposal before it is made publicly available to the community. They can then use this information to purchase tokens prior to the proposal’s public release or vote in favor of it, giving them the opportunity to affect the vote’s result or profit from the higher token price.
To lower the risk of front-running in a DAO, a clear and open decision-making process is crucial. Before the voting, proposals could be made public so that everyone has an equal opportunity to assess and discuss them.
4. Influenced Decisions
Since so many things can readily affect holders, this is the most prevalent form of crypto governance attacks.
This could be achieved when certain members or groups have a disproportionate amount of influence over decision-making, whether through influencer marketing, paid public relations campaigns, control over voting power, a large number of tokens, or even bribing people to have a biased opinion on the plan.
5. Spamming Proposals
Spamming proposals is the practice of persistently submitting a high number of low-quality proposals in order to overburden the organization and make it harder for legitimate ideas to be accepted.
This attack has the potential to interfere with decision-making, making it more challenging for the community to come to an agreement and approve important concepts.
Real-Life Case Studies of Crypto Governance Attacks
1. BeanStalk Governance Attack
In April 2022, an attack on the governance system of Beanstalk, an Ethereum-based stablecoin platform, occurred. Only $76 million of the $181 million that the attacker took from the project was retained.
Using a flash loan, the attacker may make a sizable payment to the contract. They received 79% of the votes in the governance protocol as a result, and the proposition was ultimately accepted.
2. Build Finance Governance Takeover
A governance breach that targeted Build Finance DAO on February 14, 2022, gave the attacker the ability to mint and sell tokens. From the stolen tokens, the attacker most likely made 160 ETH, or $470,000.
Since there were a sufficient number of votes in support of the plan and insufficient countervotes to stop the takeover, the attacker was successful.
DAO Governance Attacks Prevention
- Limiting the Governance Powers: Projects can lessen the impact of attacks by limiting the scope of what governance can accomplish. The breadth of possible assaults is significantly reduced when governance only permits modification of specific project aspects, as opposed to when governance permits complete control of the governing smart contract.
- Emergency shutdown: The smart contract code can have an emergency shutdown mechanism to temporarily stop all transactions and stop further damage in the event of a major security breach.
- Transparency and communication: DAOs are more likely to inspire trust and draw a devoted community of token holders who are committed to the organization’s long-term success if they are open and transparent about their operations and decision-making procedures.
- Limiting Proposals on a DAO: By limiting the quantity of proposals that can be submitted within a given time frame, DAOs can cut down on fraudulent or spam ideas. Additionally, they ought to include some kind of user authentication, like a reputation score threshold for proposals or a KYC (know your customer) check.
These are only a handful of the many strategies that can be used to protect DAOs from assaults; the ideal approach will rely on the particular requirements of the company.
Our Takeaways
In a nutshell, a well-defined and transparent decision-making process, frequent audits of the DAO smart contract, bug bounty programs, and a community of experts who can serve as watchdogs on any suspicious activity are just a few of the precautions that must be taken in order to prevent governance attacks.
To protect DAOs from such vulnerabilities, proactive measures for smart contract security are essential.
