What is prompt injection? Large language models (LLMs) – the neural network algorithms that underpin ChatGPT and other popular chatbots – are becoming ever morepowerful and inexpensive. For this reason, third-party applications that make use of them are also mushrooming, from systems for docum...
In this type of attack, hackers trick an LLM into divulging its system prompt. While a system prompt may not be sensitive information in itself, malicious actors can use it as a template to craft malicious input. If hackers' prompts look like the system prompt, the LLM is more likely to ...
Prompt engineering can manipulate AI systems into performing unintended actions or generating harmful outputs. When bad actors use carefully crafted prompts to make the model ignore previous instructions or perform unintended actions, it results in what is known as prompt injection attacks. Previous Quest...
Discovering Bing Chat’s Initial Prompt: Stanford University student Kevin Liu used a prompt injection attack to find out Bing Chat’sinitial prompt, which details how the tool can interact with users. Liu did this by instructing the tool to ignore previous instructions and to write out the “...
What is prompt injection? Since LLMs look like they know what they’re saying but are actually just repeating words and probabilities, they carry biases and can share prankish texts. Companies behind LLMs add obstacles so that the output isn’t harmful or against their rules. But by providing...
A command injection is an exploit of a system weakness to gain access to the system for the purpose of executing malicious code, harvesting user data, and engaging in other activities. While there is a potential for a command injection to be benign in nature, usually it is not, and it ...
Prompt engineering is the practice of designing inputs for large language models (LLMs) and other generative AI (genAI) tools. Successful prompt engineering refers to effective prompts that produce desired outputs.
Direct prompt injection (also called “jailbreaking”) is the process of overwriting the system prompt, which instructs the LLM on how to respond to user input. Through this tactic, the attacker might be able to access and exploit backend systems. Indirect prompt injection is when an attacker...
Prompt Injectionis a technique to hijack a language model's output. (We can get models to ignore the first part of the prompt.) Twitter users quickly figured out that they could inject their text into the bot to get it to say whatever they wanted. This works because Twitter takes a user...
Prompt engineering can also play a role in identifying and mitigating various types of prompt injection attacks. These kinds of attacks are a modern variant ofSQL injectionattacks, in which malicious actors or curious experimenters try to break the logic of generative AI services, such asChatGPT,...
