In the contract `BEC` the role `_owner` has authority over the functions: - setNoFeeWallet - changeLpPair - toggleLpPair - toggleCanSwapFees - changeWallets - setPresaleAddress - enableTrading - writeswapThreshold - setZeroTax Any compromise to the `_owner` account may allow the hacker to take advantage of this authority and include accounts in fees, exclude accounts from fees, set LP pair, enable/disable swapping, set marketing addresses, set presale addresses, enable trading, set the threshold for swapping, or set the sell fee to 0. In the contract `Ownable` the role `_newOwner` has authority over the following function: - _claimOwnership Any compromise to the `_newOwner` account may allow the hacker to take advantage of this authority and claim the ownership. In the contract `Ownable` the role `_owner` has authority over the following functions: - renounceOwnership - transferOwnership Any compromise to the `_owner` account may allow the hacker to take advantage of this authority and transfer or renounce the ownership.

All tokens are sent to `_owner` when deploying the contract. This could be a centralization risk as the `_owner` can distribute tokens without obtaining the consensus of the community.

The contract is serving as the underlying entity to interact with one or more third party protocols. The scope of the audit treats third party entities as black boxes and assume their functional correctness. However, in the real world, third parties can be compromised and this may lead to lost or stolen assets. In addition, upgrades of third parties can possibly create severe impacts, such as increasing fees of third parties, migrating to new LP pools, etc. ```solidity=177 IRouter02 public swapRouter; ``` - The contract `BEC` interacts with third party contract with `IRouter02` interface via `swapRouter`.
