How much was lost in the Bad Guys by RPF hack?

The Bad Guys by RPF hack resulted in — in losses on September 02, 2022.

What attack technique was used in the Bad Guys by RPF exploit?

The Bad Guys by RPF exploit utilized Incorrect Share Accounting. Understanding this attack vector is critical for smart contract auditors and developers building secure DeFi protocols.

How can developers prevent similar smart contract attacks?

Preventing smart contract hacks requires a combination of secure coding practices, thorough security audits, and understanding common attack vectors like reentrancy, oracle manipulation, and access control flaws. Smart Contract Hacking (SCH) provides hands-on training to help developers and auditors identify and prevent vulnerabilities before deployment.

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 incorrect share accounting and Solidity and EVM internals

Capital Required Seed capital to cover gas and initial position setup

On-Chain Access Ability to interact with ethereum smart contracts and deploy a custom exploit contract

Protocol Analysis Identification of the exploitable vulnerability in Bad Guys by RPF's contract logic - root cause: token & share accounting

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 Incorrect Share Accounting audit checklist and test coverage

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

Verify all logic paths related to Incorrect Share Accounting 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
