SHIRYO2 [Shiryo 2.0] Token

ShiryoTwo.swapBack(uint256) (#1064-1109) sends eth to arbitrary user
Dangerous calls:
- reflector.deposit{value: amountBNBReflection}() (#1108)
ShiryoTwo.transferBNBOut(uint256) (#1111-1116) sends eth to arbitrary user
Dangerous calls:

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

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.

Contract ownership is not renounced (belongs to a wallet)

ShiryoTwo.swapBack(uint256) (#1064-1109) ignores return value by dexRouter.addLiquidityETH{value: amountBNBLiquidity}(address(this),amountToLiquify,0,0,burnAddress,block.timestamp) (#1094-1101)
