# Hedera-based Bonzo protocol suffers $9m oracle exploit SAUCE token price manipulation leads to significant losses. - **Source:** [Tech in Asia](https://www.techinasia.com) - **Published:** 2026-07-12 - **Topic:** [Finance](https://brifing.si/c/finance) - **Original article:** - **On Brifing:** https://brifing.si/s/be981c91-8f85-4689-9de3-c3dc1bf804cb ## Incident Summary The Bonzo lending protocol operating on the Hedera network fell victim to an oracle attack. The attacker manipulated the price of the SAUCE token to withdraw over $9 million in assets from the protocol. This incident once again highlighted the critical importance of security in the DeFi world. ## What is an Oracle Attack? Oracle attacks involve manipulating off-chain data sources to make smart contracts operate with incorrect data. In this case, the price information of the SAUCE token was manipulated, causing the Bonzo protocol to make incorrect calculations. Attackers exploited this vulnerability to withdraw a large amount of assets from the protocol. ## About Bonzo Protocol Bonzo is a lending protocol operating on the Hedera network. It allows users to borrow by collateralizing their assets and is an important part of the DeFi ecosystem. However, this recent attack revealed that the protocol's security measures were insufficient. ## The Role of SAUCE Token SAUCE token is a digital asset used in the Bonzo protocol. The attacker manipulated the price of this token to make the protocol perform incorrect calculations. This allowed them to withdraw assets worth much more than the actual value. Token price manipulation is a common method in oracle attacks. ## DeFi Security DeFi protocols can be more vulnerable to security vulnerabilities due to their decentralized nature. Oracle attacks are one of the biggest weaknesses of these protocols. This incident with the Bonzo protocol once again reminded the DeFi world of the need for stronger security measures. ## Conclusion and Implications The $9 million loss in the Bonzo protocol has increased concerns about security in the DeFi ecosystem. Stronger measures against oracle attacks and more rigorous auditing of protocols are needed. This incident showed that investors should consider security measures when investing in DeFi projects. ## Sources covering this story - https://www.techinasia.com/news/hedera-lending-protocol-bonzo-hit-9m-oracle-exploit — --- _Summary written by Brifing from the original reporting.
