Prompt Injection

A technique where specific prompts or cues are inserted into the input data to guide the output of a machine learning model, specifically in the field of natural language processing (NLP).

Summary

Tools

Simple list of tools that can be targeted by "Prompt Injection". They can also be used to generate interesting prompts.

Challenges

Applications

In the context of models like ChatGPT and other NLP models, a "prompt" refers to the input or question that you provide to the model to get a response. It's essentially the starting point or trigger for the model to generate an output.

Prompt injections can be used in various applications of NLP models.

Story Generation

For instance, if you're using a language model to generate a story and you want the story to be about a dragon, you might inject a prompt like "Once upon a time, there was a dragon..." This prompt guides the model to generate a story that includes a dragon.

Potential Misuse

In the context of security, "prompt injection" could refer to a type of attack where an attacker manipulates the input to a system (the "prompt") in order to cause the system to behave in a way that benefits the attacker. This could involve, for example, injecting malicious code or commands into user input fields on a website.

System Prompt

The system prompt and user prompt are key concepts in conversational AI that define how the interaction between the AI and the user is shaped.

An attacker can add more instructions by following the format used by the LLM.

OpenAI Format:

{"role": "system", "content": "INJECT_HERE"}

Mixtral Format:

<<SYS>>INJECT_HERE<</SYS>>[INST]User Instruction[/INST]

Direct Prompt Injection

Direct Prompt Injection is a security vulnerability in AI-powered applications where a malicious user manipulates the prompt to make the AI ignore its original instructions and execute unintended commands.

Here are a list of basic prompts to test against NLP models.

Indirect Prompt Injection

Indirect Prompt Injection is a type of security vulnerability that occurs in systems using AI, particularly Large Language Models (LLMs), where user-provided input is processed without proper sanitization. This type of attack is "indirect" because the malicious payload is not directly inserted by the attacker into the conversation or query but is embedded in external data sources that the AI accesses and uses during its processing.

Examples of Indirect Prompt medium:
