Prompt injection

Sketch: a fake Turn here sign is pasted over a real shop sign; then a car swerves off the road toward it.

Prompt injection is when hidden or sneaky text in a webpage, email or file tricks an AI into ignoring your instructions.

Think of it like this: It is a fake road sign that tells your self-driving car to turn somewhere you never asked to go.
