How much was lost in the EthBread Token hack?

The EthBread Token hack resulted in $787K in losses on June 25, 2023.

What attack technique was used in the EthBread Token exploit?

The EthBread Token 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

EthBread project was rugpulled by multiple addresses, who drained 786,574 $USD from PancakeSwap.

Details of the Exploit

$ETB, a token on Binance Smart Chain, experienced a significant liquidity drain from PancakeSwap. After initially distributing $ETB tokens to multiple addresses on February 16, 2023, large-scale removal of liquidity took place on June 25, 2023. Multiple addresses, linked to the deployer, collectively removed approximately 786,574 $USD from the ETB/USDT pool.

One of the directly associated addresses removed liquidity amounting to 135,291 $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 EthBread Token'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 EthBread Token, these are the critical security checks that could have prevented this incident (June 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
