How much was lost in the BABYFIDO hack?

The BABYFIDO hack resulted in $79K in losses on November 14, 2023.

What attack technique was used in the BABYFIDO exploit?

The BABYFIDO 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

BABYFIDO token was rugpulled, the scammer removed liquidity worth 79,306 USD from UniSwap pool, resulting in a 39.42 WETH loss.

Details of the Exploit

BABYFIDO is an ERC20 token trading on UniSwap. On Nov 14, 2023.The scammer swapped a significantly larger number of tokens, completely depleting the liquidity pool worth 39.42 WETH or approximately 79,306 USD. The stolen funds were transferred to another EOA and then added to the liquidity pool of another token through a another scammer's address.

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 BABYFIDO'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 BABYFIDO, 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
