Abstract

Large Language Models (LLMs) are increasingly being integrated into applications, with versatile functionalities that can be easily modulated via natural language prompts. So far, it was assumed that the user is directly prompting the LLM. But, what if it is not the user prompting? We show that LLM-Integrated Applications blur the line between data and instructions and reveal several new attack vectors, using Indirect Prompt Injection, that enable adversaries to remotely (i.e., without a direct interface) exploit LLM-integrated applications by strategically injecting prompts into data likely to be retrieved at inference time. We derive a comprehensive taxonomy from a computer security perspective to broadly investigate impacts and vulnerabilities, including data theft, worming, information ecosystem contamination, and other novel security risks. We then demonstrate the practical viability of our attacks against both real-world systems, such as Bing Chat and code-completion engines, and GPT-4 synthetic applications. We show how processing retrieved prompts can act as arbitrary code execution, manipulate the application's functionality, and control how and if other APIs are called. Despite the increasing reliance on LLMs, effective mitigations of these emerging threats are lacking. By raising awareness of these vulnerabilities, we aim to promote the safe and responsible deployment of these powerful models and the development of robust defenses that protect users from potential attacks.

TL;DR

The paper introduces indirect prompt injection, where adversaries place prompts in data that LLM-integrated applications retrieve, allowing remote manipulation without directly prompting the model. It develops a security taxonomy and demonstrates practical attacks against Bing Chat, GitHub Copilot, and synthetic GPT-4/text-davinci-003 applications, covering data theft, fraud, malware, intrusion, content manipulation, and availability disruption.

Key findings

  • Retrieved content can function like instructions, letting third-party data steer model behavior; the authors report that all described proof-of-concept demonstrations triggered the intended behavior.
  • Attacks can persuade users to reveal personal information, exfiltrate data through side effects such as URL retrieval, distribute phishing or malware links, and turn prompts into self-propagating “AI malware” that reads address books and forwards injections by email.
  • Intrusion demonstrations include remote control by fetching new commands from an attacker-controlled server, persistence through memory reinfection, and contamination of code-completion suggestions; content-manipulation demonstrations include wrong summaries, source blocking, disinformation, and undisclosed advertisements.
  • Hidden-injection methods include multi-stage payload retrieval and a Base64-encoded prompt that worked on Bing Chat; the model also sometimes issued follow-up search queries that reinforced the injected prompt.

Methods

  • The authors build a threat model and taxonomy from a computer security perspective, classifying injection delivery as passive retrieval, active delivery, user-driven, or hidden, and mapping threats to affected parties.
  • Synthetic applications used OpenAI APIs: text-davinci-003 with LangChain and ReAct prompting, and GPT-4 in chat format, with mock tools for search, viewing pages, retrieving URLs, reading/sending email, reading an address book, and memory; all interfaces returned prepared content, no real systems were contacted, and attacks ran at sampling temperature 0.
  • Real-world black-box tests targeted Bing Chat, including its Edge sidebar reading local HTML files, and GitHub Copilot/Codex for code-completion manipulation; prompts were manually written, and local HTML was used to avoid public injections.

Limitations

  • The paper states that attacks were tested on local HTML files rather than public in-the-wild injections, that Microsoft 365 Copilot and ChatGPT plugins were inaccessible, that success rates are hard to quantify in dynamic interactive sessions, that believability was assessed qualitatively, and that exact reproducibility is difficult in black-box systems.
  • The text also makes evident that code-completion injections were highly context-sensitive and lost efficacy in larger packages or projects, and that some availability attacks, such as inhibiting API calls, succeeded only inconsistently.
  • The authors note that user studies are needed to quantify deception potential across different attacks and setups.

    From AI Agents vs. Agentic AI: A Conceptual taxonomy, applications and challenges (2026) · cites this paper as [61]

    The Introduction says LLM-integrated systems can act on a user's behalf by calling APIs, and Synthetic Applications describes an agent given a specified subset of tools. Empirical Foundations of Attacks says models might autonomously initiate conversations or issue actions. But the paper uses “agent,” “LLM,” and “model” interchangeably; it does not establish the claimed distinction between agents and LLMs or characterize agents as producing actionable outputs in real-time environments.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-11.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-11.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
