It’s never just one hack these days. Take the [Target hack](https://www.zdnet.com/article/anatomy-of-the-target-data-breach-missed-opportunities-and-lessons-learned/) of 2013, the attackers broke into what appears to have been a smart-fridge, before using that as a jumping-off point to probe the rest of the Target network, until they found a way to break into their point-of-sale system, where they could steal credit card data.
