Since the OP didn't include a link I'm assuming "Binance one-stop platform" is a vetted subset of all Binance Smart Chain platforms. In the case of this article I'm pretty sure Binance has not endorsed the "hacked" platform. I think the BSC is an open network and anyone can create their own smartcontracts in there. A popular new platform on BSC goosedefi has been forked hundreds of times, and most of them have failed within days with either developers or early users dumping the price. It's a big risk putting your money on any of these platforms, most of them are basically elaborate ponzi schemes promising big APR but leaves people bagholding a worthless token. A very few lucky platforms with good developers go on and become stable established defi platforms like sushiswap.
