Incident Overview

Quick Summary

FloorDAO has experienced an exploit leading to the loss of around 40 $ETH (~$65,000).

Details of the Exploit

FloorDAO has experienced an exploit leading to the loss of around 40 $ETH (~$65,000). The attack was attributed to design flaws in the "distribute" and "rebase" functions.

The attacker was funded by TornadoCash and successfully acquired 40 $ETH, equivalent to $65,000. All the compromised funds have been deposited into the address 0xd3b8.

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 FloorDAO'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 FloorDAO, these are the critical security checks that could have prevented this incident (September 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
