Incident Overview

Quick Summary

NFT Cloud platform was exploited, which caused a loss of 85,330 $USD worth of $BNB.

Details of the Exploit

NFT Cloud is a Web3 platform for entrepreneurs and creators. The staking contract of the platform was exploited due to an indexing-related logic issue. The attacker was able to receive 100,000 $CLOUD tokens using a malicious contract with an unverified source code, and then drain the PancakeSwap liquidity pool.

The token price dropped by more than 75% cause of an exploit. The total funds lost reached roughly 265 $BNB which is worth 85,300 $USD at the moment. All the stolen funds were transferred through TornadoCash.

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 NFT Cloud's contract logic - root cause: nft,token
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 NFT Cloud, these are the critical security checks that could have prevented this incident (February 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
