Incident Overview

Quick Summary

The MINER's smart contract was exploited, resulting in a loss of 466,624 USD worth 168.6 WETH.

Details of the Exploit

MINER is a collection of 100,000 avatars tied to the first tokens built on ERC-X, a fully optimized, experimental standard that enables the use of multiple token standards. On Feb 14, 2024, the project was exploited due to a double-transfer vulnerability caused by a lack of input validation in the update function. The attacker performed several malicious transactions, exploiting the vulnerability to get free tokens by sending tokens to themselves.

The stolen funds were transferred to another EOA and still remain in this address as of Feb 17, 2024. The MINER team posted on their platform that they have sent an on-chain message to the hacker, offering a bounty of 120,000 USD, approximately equivalent to 25% of the exploited funds.

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 MINER's contract logic - root cause: 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 MINER, 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
