Incident Overview

Quick Summary

Hacker exploited SpiritSwap's domain and gain assets about 18,000 $USD

Details of the Exploit

SpiritSwap is a DEX on the Fantom blockchain. The hacker exploited www.spiritswap.finance domain and replaced swap parameters, so swapped tokens were transfered to this address. Roughly 18,000 $USD was stolen this way.

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 phishing 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 SpiritSwap's contract logic - root cause: exchange (dex)
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 Phishing audit checklist and test coverage

If you're auditing a protocol with similar architecture to SpiritSwap, these are the critical security checks that could have prevented this incident (May 2022).

  • Verify all logic paths related to Phishing are guarded by proper access controls and input validation - see the Phishing Attacks attack class for patterns
  • Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
