Incident Overview

Quick Summary

LandNFT project experienced an exitscam. The scammer allowed to create of 200 NFTs that were sold for 145,043 $USD.

Details of the Exploit

LandNFT is an NFT project on Binance Smart Chain (BSC). An investigation revealed that some miner addresses had unlimited ability to mint NFTs, including one with the address: 0x2e599883…0e3ac7. The attack started by calling the contract owned by this miner's address to mint 200 NTFs without any restrictions or permissions.

Next, the scammer called another function from another contract using these newly created tokens to swap them for $XQJ tokens at a rate of 200 $XQJ per token. Finally, they exchanged all accumulated $XQJ tokens for 145,043 $USD. The stolen funds currently remain at the scammers original address.

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 land'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
Audited by Audit Report 1 — still lost $145K. Prior audits don't guarantee safety, especially after post-audit code changes.

If you're auditing a protocol with similar architecture to land, these are the critical security checks that could have prevented this incident (May 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
