Incident Overview

Quick Summary

DD coin's Marketplace contract was exploited. The attacker increased their allowances and profited for 306,597 $USD.

Details of the Exploit

DD coin is a BEP20 token trading on PancakeSwap. DD coin's Marketplace smart contract had a vulnerability that allowed an attacker to increase their allowances by simulating multiple buy/sell actions from their newly deployed smart contracts and the main malicious smart contract. This gave them enough access to withdraw 306,597 $USD worth of tokens from the Marketplace contract.

Over 80 fake buyer contracts were deployed during this process which resulted in two similar transactions where all these actions occurred. The stolen funds were transferred to another EOA 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 DD coin's contract logic - root cause: other
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 DD coin, these are the critical security checks that could have prevented this incident (June 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
