LSHIB [LuckyShibaInu] Token

LuckyShibaInu.withdrawForeignToken(address) (#637-640) ignores return value by IERC20(address(token)).transfer(msg.sender,IERC20(token).balanceOf(address(this))) (#639)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

LuckyShibaInu.swapBNBForTokens(uint256) (#1256-1268) sends eth to arbitrary user
Dangerous calls:

LuckyShibaInu.addLiquidity(uint256,uint256) (#1273-1287) sends eth to arbitrary user
Dangerous calls:
- _pancakeswapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp.add(300)) (#1279-1286)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

LuckyShibaInu.random() (#859-864) uses a weak PRNG: "r = uint256(uint256(keccak256(bytes)(abi.encodePacked(block.difficulty,block.timestamp,_nonce))) % 1000) (#860)"

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Combination 2: Unchecked transfer + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Combination 3: Reentrancy vulnerabilities + Unchecked transfer vulnerability. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

LuckyShibaInu._rTotal (#540) is set pre-construction with a non-constant function or state variable:
- (MAX - (MAX % _tTotal))
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.

LuckyShibaInu._tokenTransfer(address,address,uint256) (#1116-1151) performs a multiplication on the result of a division:

LuckyShibaInu.swapAndLiquify(uint256) (#1201-1230) performs a multiplication on the result of a division:
