Exploits Involving Oracle Networks Have Resulted in Over $892 Million in Losses, Binance Research Reports
A recent report from Binance Research reveals that exploits related to oracle networks have caused losses amounting to nearly a billion dollars over the past three years. Oracles play a crucial role in connecting blockchains to external data, enabling smart contracts to execute tasks based on real-world events or conditions. DeFi protocols rely on oracles to fetch the market price of assets, which determines whether certain transactions should be facilitated. However, Binance Research highlights that the reliability of real-world data from different sources varies, making systems vulnerable to manipulation.
The report cites several instances of malicious actors exploiting this weakness to manipulate price feeds and drain funds from platforms. Notable examples include the Mango Markets breach last year and the attack on EraLend in July 2023.
The Scale of Exploitation
According to Binance Research, an estimated $892 million has been exploited through oracle-related manipulations since 2020. Malicious actors often drive up the prices of low-liquidity tokens on targeted protocols before swapping them for other tokens or using them as collateral for loans in lending markets.
In 2021, the total value hacked in oracle-related exploits reached $399.1 million, marking a significant increase from $65 million in 2020. The peak occurred in 2022 with losses amounting to $403.2 million, followed by a decline to $25.4 million in 2023.
Factors Contributing to Decline
Binance Research identifies two factors that have contributed to the decrease in oracle-related exploits this year. First, there has been an increased focus on security measures within the industry. Second, there has been a broad decline in DeFi TVL (total value locked).
Hot Take: Protecting DeFi Platforms from Oracle Exploits
The prevalence of exploits involving oracle networks highlights the need for enhanced security measures within the DeFi ecosystem. To mitigate these risks, platforms should prioritize the use of reliable and verified data sources. Implementing robust monitoring systems and conducting regular audits can also help identify and address vulnerabilities. Additionally, collaborations between platforms and security experts can contribute to the development of best practices and protocols that safeguard against oracle-related manipulations. By taking proactive steps to protect against these exploits, the DeFi industry can continue to grow and thrive.
