Input manipulation

When an attacker crafts a malicious input to exploit the model's behavior

The Explain card

Plain English
Input manipulation is crafting a malicious input to exploit how a model behaves, whether that is a subtly altered image, a tweaked audio clip, or a carefully worded prompt.
Example
An attacker adds faint noise to a stop-sign photo. A human still sees a stop sign; the vehicle's vision model confidently reads "speed limit 45."
Why it matters
Models are decision-makers you cannot fully inspect, and they fail in ways humans would not. Defenders use adversarial testing, input validation, and redundancy so one crafted input cannot trigger a bad action.
Hook
Small change to the input, big change to the verdict.
