A lot of it is big brand products as well. How, in the 21st century, is this possible, and with such frequency? Is software running on electronic hardware invariably open to hacking if someone just tries long and hard enough? Or are the product manufacturers simply careless or cutting corners in their product designs? If you create something that communicates with other things electronically, is there no way at all to ensure that the device is practically unhackable?
