Written by Ohris M. Greyoon, Blockchain & Crypto Expert
- Exploit Confirmation: The IPOR team confirmed that a legacy Fusion Optimizer vault on Arbitrum was exploited, resulting in a loss of approximately $336,000 USDC, which, while less than 1% of total funds secured by the Fusion system, still impacts user confidence significantly.
- Vulnerability Analysis: The flaw in the contract implemented through EIP-7702 allowed attackers to deploy malicious contracts within the PlasmaVault architecture, highlighting deficiencies in the project team's contract security that necessitate enhanced review and testing protocols.
- Response Measures: The IPOR team is collaborating with security organizations to trace the stolen funds and has committed to fully reimbursing affected depositors from its treasury, demonstrating a strong commitment to user fund safety and accountability.
- Future Security Assurance: IPOR emphasized that additional safeguards have been implemented and confirmed no further vulnerabilities exist across other Fusion vaults, aiming to restore user trust and ensure the security of future operations.
