Web3 Security Insights from Q2 2024: A Mixed Bag of Progress and Challenges


The second quarter of 2024 brought a dynamic shift in the Web3 security landscape. While the number of hacks saw a noticeable decline compared to the previous quarter, the total funds lost tell a more complex story. In this report, we delve into the key findings from Hacken’s Q2 2024 Web3 Security Report to uncover the trends, challenges, and the evolving nature of security in the decentralized world.

Key Observations from Q2 2024

1. Decline in Hacks but an Increase in Losses

Despite a significant reduction in the number of hacking incidents in Q2 2024 (down to 41 from 67 in Q1), the total amount of funds stolen surged dramatically. This quarter saw over $512 million siphoned off from various Web3 projects, which is alarmingly close to the total losses for the entire first half of 2024​(web3-security-report-q2…)​.

2. Access Control Issues Continue to Dominate

Access control vulnerabilities remained the most significant contributor to financial losses. These issues, which include failures in managing permissions and securing private keys, were responsible for the largest chunk of the funds stolen, amounting to $397 million in Q2 alone​(web3-security-report-q2…)​.

3. Major Incidents of the Quarter

  • Rain Exchange Hack: This attack resulted from compromised private keys, leading to a $14.8 million loss. The funds were quickly converted to BTC and ETH before being transferred to unidentified wallets​(web3-security-report-q2…)​.
  • DMM Bitcoin Incident: In May 2024, one of the year's biggest hacks saw over $305 million worth of Bitcoin moved to unknown addresses. The hack's scale highlights the critical need for enhanced security protocols in handling large-scale digital assets​(web3-security-report-q2…)​.

Types of Attacks and Their Impact

1. Flash Loan Attacks and Rug Pulls

These types of exploits remained prevalent in Q2 2024. Flash loan attacks, which manipulate the price oracles to exploit vulnerabilities in DeFi protocols, and rug pulls, where developers drain funds from their projects, were significant contributors to the overall loss in the ecosystem​(web3-security-report-q2…)​.

2. Phishing and Social Engineering

The rapid innovation in the Web3 space continues to outpace security measures, making new projects susceptible to phishing and social engineering attacks. These sophisticated methods exploit human factors to gain unauthorized access to critical assets and information​(web3-security-report-q2…)​.

Types of Projects Affected

1. Tokens and DeFi Protocols

Token-based projects experienced the highest number of hacks in Q2 2024, driven by the explosive growth and complexity of the DeFi sector. This category often includes new and innovative projects that, while groundbreaking, may overlook comprehensive security measures in their rush to market​(web3-security-report-q2…)​.

2. CeFi and Cross-Chain Platforms

Centralized Finance (CeFi) platforms and cross-chain protocols were also heavily targeted. The significant losses from incidents like the Rain Exchange hack underscore the critical need for robust security practices across all types of platforms​(web3-security-report-q2…)​.

Lessons Learned and Recommendations

1. Enhanced Access Control Measures

Implementing strong access control protocols, including multi-signature wallets and decentralized fund management, can help mitigate the risk of large-scale breaches. Ensuring only authorized personnel have access to critical system functions is crucial​(web3-security-report-q2…)​.

2. Comprehensive Security Audits

Projects must prioritize thorough security audits and regular assessments to identify and address potential vulnerabilities. This is especially vital for new and rapidly evolving projects in the DeFi and token sectors​(web3-security-report-q2…)​.

3. Community Vigilance and Education

The decentralized nature of Web3 requires a vigilant and well-informed community. Raising awareness about the latest security threats and best practices can empower users and developers to protect their assets and projects effectively​(web3-security-report-q2…)​.


Q2 2024 was a quarter of contrasting trends in the Web3 security landscape. While the reduction in the number of hacks is a positive sign, the substantial increase in the amount of funds stolen highlights the ongoing challenges in securing the rapidly evolving digital ecosystem. As the Web3 space continues to grow, the need for robust security measures and vigilant practices becomes ever more critical.
