Incident Overview

Quick Summary

Fortunas Finance was exploited using smart contract vulnerability. The hacker minted $FRTNA tokens and sold them on PancakeSwap and KnightSwap which dumped the token price by more than 99% on both pools.

Details of the Exploit

Fortunas Finance is a gamified crypto project. The project's token $FRTNA was hacked using a vulnerability in the liquidity pool's smart contracts. The hacker used mint() function to mint tokens without $BUSD, and profit for the total amount of 21,672 $BUSD.

Several smart contracts with unverified source code were used to perform an attack. The stolen funds were transferred to another contract.

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 Fortunas Finance'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
Audited by Audit Report 1 — still lost $22K. Prior audits don't guarantee safety, especially after post-audit code changes.

If you're auditing a protocol with similar architecture to Fortunas Finance, these are the critical security checks that could have prevented this incident (September 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
