Shoulder surfing

Some secrets leak without anybody touching a system at all. They are read off a screen on a train, a whiteboard behind someone on a video call, or a keyboard being typed at.

It sounds quaint until you notice how much is now on camera. Office whiteboards, shared screens, and the background of every remote meeting, all being recorded. A password taped to a monitor used to be visible to whoever walked past. Now it is visible to everyone in the meeting and anyone who watches the recording afterwards.
