NBR [NIBIRUVERSE] Token

BNBDistributor.distributeDividend(address,address) (#261-272) sends eth to arbitrary user
Dangerous calls:
- address(receiver).transfer(_accured[giveholder]) (#267)
NIBIRUVERSE.swapBack() (#541-598) sends eth to arbitrary user
Dangerous calls:
- address(marketingFeeReceiver).transfer(bnbSwapMarketingAmount) (#578)
- address(bnbDistributor).transfer(bnbSwapBnbAmount) (#582)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

BNBDistributor.claimDividend(address) (#274-281) uses a dangerous strict equality:

Don't use strict equality to determine if an account has enough Ether or tokens.

NIBIRUVERSE._transferFrom(address,address,uint256) (#441-498) contains a tautology or contradiction:

NIBIRUVERSE._basicTransfer(address,address,uint256) (#505-511) contains a tautology or contradiction:
- require(bool,string)(balanceOf(sender).sub(amount) >= 0,Insufficient Balance) (#506)
Fix the incorrect comparison by changing the value type or the comparison.

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.

NIBIRUVERSE.swapBack() (#541-598) performs a multiplication on the result of a division:
-bnbLiquidify = swapedBNBAmount.mul(liquidityFee.div(2)).div(bnbDenom) (#575)
Consider ordering multiplication before division.

Pragma version^0.8.10 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.10 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
