A Prompt-Injection Attack is a manipulation that hides instructions inside content a generative system reads, causing it to behave in unintended ways. This can poison what a system says about a brand and is an emerging tool for coordinated reputational attack.

Prompt-Injection Attack matters because AI engines now mediate how people discover brands, interpret categories, and decide which sources are credible. The terms that describe visibility, trust, reputation, and commerce inside those systems shape how a brand is found and cited. Communications teams must understand this risk as prompt injection can directly impact brand reputation in AI-driven environments.
