5. Hacker Uses Flashloan to Exploit Logic Vulnerability on KaoyaSwap
On August 24, an attacker had exploited more than US$110, 000 worth of crypto assets on KaoyaSwap, a Defi application deployed on the BNB chain.
KaoyaSwap had implemented a proxy/implementation pattern, of which, the proxy contract was deployed at: 0x879ead67c92ec2bfa70fa9d157f500b7b31b64ab
while the implementation was deployed at: 0x97AF028838604C59F93B279D3B6f6cBbF74bc680
In the pattern, a logic vulnerability was found in the “swapExactTokensForETHSupportingFeeOnTransferTokens” function.
The attacker borrowed 1, 800 BNBs through a flashloan, made two token pairs by using the BNBs and another two tokens, and provided the liquidity to the application. The attacker then proceeded to repeatedly execute the vulnerable token-swap function and eventually obtained a net quantity of 37, 294 BUSDs and 271 WBNBs after returning the flashloan.
