UKRAINE SOLIDARITY Token

UKRAINE.airdrop(address) (#550-563) sends eth to arbitrary user
Dangerous calls:
- address(uint160(_refer)).transfer(referEth) (#559)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Additional information: link

UKRAINE.recoverERC20(address,uint256) (#582-584) ignores return value by IERC20(tokenAddress).transfer(owner(),tokenAmount) (#583)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Contract creator or owner is blacklisted for past scams

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

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.

Contract ownership is not renounced (belongs to a wallet)
