Devia8.swapBack() (#1254-1298) sends eth to arbitrary user
Dangerous calls:
- (success,None) = address(buyBackWallet).call{value: ethForBuyBack}() (#1289)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Devia8._transfer(address,address,uint256) (#1102-1217) uses a dangerous strict equality:
- tradingActiveBlock == block.number && (automatedMarketMakerPairs[to] || automatedMarketMakerPairs[from]) (#1186)
Don't use strict equality to determine if an account has enough Ether or tokens.

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.

Devia8._transfer(address,address,uint256) (#1102-1217) performs a multiplication on the result of a division:
-fees = amount.mul(sellTotalFees).div(100) (#1194)
-tokensForBuyBack += fees * sellBuyBackFee / sellTotalFees (#1198)
Consider ordering multiplication before division.
