Incident Overview

Quick Summary

On January 30, 2023, the BEVO NFT art token $BEVO was exploited resulting in a total loss of approximately $45,000.

Details of the Exploit

$45,000 was lost due to an exploit on the BEVO NFT art token. The attack was caused by the deflationary nature of the $BEVO token, resulting in a decrease in the token's total value. The exploiter took a flash loan, swapped it for $BEVO tokens, manipulated the token balance, and made a profit of 144 $WBNB.

As a result, the price of $BEVO token plummeted by 99%.

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 BEVO NFT's contract logic - root cause: nft
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 BEVO NFT, these are the critical security checks that could have prevented this incident (January 2023).

  • 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
