How much was lost in the Do Right hack?

The Do Right hack resulted in $371K in losses on December 15, 2023.

What attack technique was used in the Do Right exploit?

The Do Right 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

DR token was rugpulled by deployer, removing liquidity worth 370,556 USD from PancakeSwap.

Details of the Exploit

DR is a BEP20 token trading on PancakeSwap. The deployer removed liquidity from the LP pool within two days, selling tokens in 13 transactions totaling 290,547 USD and removing 80,009 USD in another transaction. The stolen funds were transferred to another EOA address and still remain in that address as BSC-USD.

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 Do Right'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 Do Right, these are the critical security checks that could have prevented this incident (December 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
