LuckyDoge Token

LuckyDoge._transfer(address,address,uint256) (#929-1052) uses a weak PRNG: "_bBSLimit = _bBSLimitMin + (uint256(keccak256(bytes)(abi.encodePacked(msg.sender,block.timestamp,block.difficulty,blockhash(uint256)(block.number - 1)))) % (_bBSLimitMax - _bBSLimitMin + 1)) (#1005-1015)"
Do not use block.timestamp, now or blockhash as a source of randomness

LuckyDoge.swapETHForTokens(uint256) (#1092-1109) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.swapExactETHForTokensSupportingFeeOnTransferTokens{value: amount}(0,path,deadAddress,block.timestamp.add(300)) (#1099-1106)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

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.
