Prompt injection

Level 3

Hiding instructions inside content so a model obeys the attacker instead of you.

Term 4 of 6 in Safety and privacy

In plain language

If a model reads a web page or email, any text in it can be read as an instruction. Hidden text can tell an agent to leak data or take an unwanted action.

Think of it like this

Slipping a forged note into a courier's pouch and having it followed without question.

Why it matters

Prompt injection is the main security risk of AI agents, and the reason autonomous tools need strict limits on what they can reach.
