The testing scenarios presented here serve as illustrative examples to support high-level security test development. More detailed threat models for each of OWASP T10 LLM and AI Exchange threats could account for AI deployment specific data flows, technology stack, model behavior, and the infrastructure supporting development and deployment. The threat model should also incorporate structured frameworks such as MITRE ATT\&CK. This enables precise mapping of attack vectors and supports specific adversarial testing aligned with real-world exploitation techniques, as addressed in the Attack Modeling and Vulnerability Analysis stages of the PASTA threat modeling methodology.*

Prompt injection vulnerabilities occur when user-provided prompts directly manipulate a large language model's (LLM) intended behavior, causing unintended or malicious outcomes. This includes overriding system prompts, exposing sensitive information, or performing unauthorized actions. In this section we analyse the basic Prompt injection techniques: dedicating separate testing for system prompts, sensitive information, unauthorized or harmful action.

A prompt injection includes (see. Lakera reference):

- Instructions of what the testers wants the AI to do.

- Instructions of what the testers want the AI to do.
|

- A “trigger” that causes the LLM to follow the user’s instructions instead, i.e. phrases, obfuscation methods, or role-playing cues that bypass safeguards.
|
||||
- Malicious intent. The instructions must conflict with the AI’s original system constraints. This is what makes it an attack.
|
||||
The way these elements interact determines whether an attack succeeds or fails—and why traditional filtering methods struggle to keep up.
