Incident Overview

Blueberry DeFi leverage project exploited due to a contract vulnerability, resulting in the loss of 91 $ETH or approximately 266,023 $USD.

Blueberry, a decentralized financial lending and leverage protocol, suffered an exploit on February 23, 2024.An attacker attempted to exploit the vulnerability, but was overtaken by c0ffeebabe.eth, a well-known MEV bot and whitehat operator that had previously beaten other exploits and returned funds to projects. Initially 457.7 ETH was withdrawn from the project, but 366.6 ETH was of that was able to be returned.The remaining 91 ETH, worth about $1,350,000, was lost due to validator payments.

What the Attacker Needed to Succeed

Understanding the prerequisites for this type of attack helps auditors identify protocols that are most at risk and helps developers build better defenses.

Technical Knowledge Deep understanding of other and Solidity and EVM internals
Capital Required Seed capital to cover gas and initial position setup
On-Chain Access Ability to interact with smart contracts and deploy a custom exploit contract
Protocol Analysis Identification of the exploitable vulnerability in Blueberry Protocol Foundation's contract logic - root cause: yield aggregator,borrowing and lending
Execution Speed Precise transaction ordering and timing to exploit the vulnerability within a single atomic block
Obfuscation Plan A strategy to launder and move stolen funds - typically through mixers, cross-chain bridges, or decentralized DEX swaps to resist tracing

What Auditors Should Check

Could this have been caught in audit? Likely — with a thorough Other audit checklist and test coverage

If you're auditing a protocol with similar architecture to Blueberry Protocol Foundation, these are the critical security checks that could have prevented this incident (February 2024).

  • Verify all logic paths related to Other are guarded by proper access controls and input validation
  • Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
