Incident Overview

Quick Summary

$BGLD was exploited while the token migration process.

Details of the Exploit

The attack was possible in the reason of the price difference between the two versions of the BGLD token while the migration process.

The attacker took a 125 BNB flashloan and bought almost all the balance of the WBNB/BGLD pair in BGLD token. Then complete the migrating process via migratory contract and swapped out the new version on BGLD to DEBT and then to WBNB token.

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 BlackGold'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 BlackGold, these are the critical security checks that could have prevented this incident (December 2022).

  • 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
