How much was lost in the KHABY Fan Token hack?

The KHABY Fan Token hack resulted in $33K in losses on October 12, 2022.

What attack technique was used in the KHABY Fan Token exploit?

The KHABY Fan 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

KHABY Fan Token was rugpulled for 32,814 $USD. Liquidity was removed by the token deployer.

Details of the Exploit

KHABY Fan Token is BEP20 token trading on PancakeSwap and can't be confused with other tokens with the same name and symbol. The token deployer added liquidity for 250 $WBNB and after some period removed 373 $WBNB from the pool, which caused the $KFT token price to drop by 100%. The stolen funds were transferred to another EOA 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 KHABY Fan 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 KHABY Fan Token, these are the critical security checks that could have prevented this incident (October 2022).

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
