So the digital equivalent of money in the back of the couch.

所以数字相当于沙发后面的钱。

For example, your webcam can be hacked by creating a remote access tool which is the digital equivalent of someone adding an unlocked window to your home without you even noticing.

例如，网络摄像头可以通过创建远程访问工具被黑客入侵，该工具相当于有人在你家中添加了一个未上锁的窗口，而你甚至没有注意到。
