Etymology: "Backdoors" is simply the plural of "backdoor," and the word is a plain compound: "back" joined to "door." Both parts are ancient native English material. "Back" descends from Old English "bæc," and "door" from Old English "duru," so the word was built entirely from inherited Germanic vocabulary rather than borrowed from Latin or French. The literal sense, a door at the rear of a building, is where the figurative meaning grows from. A back door is an exit used out of sight of the main entrance, which makes it a natural image for a way in or out that avoids notice. That idea of a route that bypasses the official front is what carries over when the word is applied to computers, where a concealed entry point lets someone get around the usual protections.
