Incident Overview

Quick Summary

Wettok Market project was rugpulled by its deployer who stole assets worth 189,905 $USD including 164,996 $USDT and 103 $BNB.

Details of the Exploit

Wettok Market (WTO) is a BEP20 token trading on the PancakeSwap. The token deployer minted 1 billion $WTO tokens to an EOA address controlled by the scammer. The scammer drained the liquidity pool through multiple transactions, causing significant financial loss.

Notably, 100 $BNB, part of the stolen assets, were transferred through TornadoCash, making the tracing of funds more challenging. At the moment, the remainder of the funds is still held at the scammer's address as of July 22, 2023. In a subsequent move, the scammer burnt the remaining 993 million $WTO tokens.

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 rugpull 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 Wettok Market's contract logic - root cause: token,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? Hard to catch — private key / OpSec failures are outside smart contract audit scope

If you're auditing a protocol with similar architecture to Wettok Market, these are the critical security checks that could have prevented this incident (July 2023).

  • Verify all logic paths related to Rugpull 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
