How much was lost in the RepubliK hack?

The RepubliK hack resulted in $121K in losses on November 23, 2023.

What attack technique was used in the RepubliK exploit?

The RepubliK exploit utilized Rugpull. 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.

Incident Overview

Quick Summary

RPK token was rugpulled by deployer, removing liquidity of 235,995 USD from PancakeSwap pool and transferring funds to multiple addresses.

Details of the Exploit

RPK is a BEP20 token trading on PancakeSwap. On Nov 23, 2023, the deployer performed an exit scam by removing liquidity from the LP pool. The stolen funds, worth 121,445 USD (513.77 WBNB), were transferred to another EOA address and then distributed between multiple addresses.

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 RepubliK'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? Hard to catch — private key / OpSec failures are outside smart contract audit scope

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