Hidden or hard-to-notice text can influence an AI when an application passes it to the model and the model interprets it. A webpage or document can carry instructions that affect an AI processing that material—a risk known as indirect prompt injection. That does not mean every hidden string will work or automatically compromise a device: the possible impact depends on the application’s permissions, connected tools, and safeguards.
How can invisible text reach an AI?
An AI model responds to the content it receives, not only to what a person can see on screen. A document or webpage may include text that is visually obscured or encoded in a way that is difficult for a person to notice. If the application extracts that content and supplies it to the model, the model may parse it and be influenced by it. OWASP’s prompt injection guidance describes inputs that can be imperceptible to humans while still being processed by a model; its prevention cheat sheet also covers hidden and encoded content patterns.

“Invisible text” can refer to different techniques, including text hidden in a page or document’s presentation and characters that are hard to notice. The key question is whether the AI application’s input pipeline passes a representation of that material to the model. If it does not, that material cannot influence the model through that route.
What is indirect prompt injection?
Prompt injection is an attempt to alter a model’s behavior or output through instructions it receives. In a direct injection, the instructions come from the user’s own input. In an indirect injection, they arrive through external content the AI is asked to process, such as an uploaded file or a webpage. The person currently chatting with the AI does not have to be the person who placed the instructions in that content. OWASP distinguishes these paths in its current guidance and an earlier explanation.

What could happen—and what does not follow automatically?
Imagine asking an assistant to summarize a webpage. The page also contains instructions aimed at the AI. If the application sends those instructions to the model and the model follows them, the summary or later behavior could be steered away from the user’s request. The result might be a misleading answer; OWASP also identifies sensitive-information disclosure and risks involving connected functionality as possible consequences.
Influencing an answer is not the same as taking control of a computer. A hidden instruction does not guarantee success, and it does not by itself grant access to private files, accounts, or tools. Whether an attempted injection can cause a consequential action depends on the surrounding application: what information it exposes, which functions the model can invoke, and what authorization checks or human approvals are in place. OWASP’s risk guidance discusses these impacts without treating every injection attempt as successful.
How can developers reduce the risk?
No single filter should be treated as a guarantee. OWASP says it is unclear whether fool-proof prevention is possible, so the practical aim is to reduce the chance of successful manipulation and limit its impact. Useful controls include:

Treat retrieved webpages, uploaded files, email, and tool output as data to analyze, not as authoritative instructions. Keep those sources clearly identified and separated from trusted system directions.
- Limit access and permissions. Give the model and the application only the data and tools required for the task. Enforce access rules in application code rather than asking the model to decide whether it may access sensitive information.
- Gate high-impact actions. Require independent confirmation or human approval before sending or deleting information or taking another consequential action.
- Check inputs and outputs. Validate expected formats and use input and output checks as supporting controls; do not assume they will catch every indirect instruction.
- Test realistic attack paths. Adversarially test the application with external content it may encounter, and repeat testing when its models, tools, or workflows change.
These measures align with the controls in the OWASP GenAI guidance and the OWASP prevention cheat sheet.

- Be cautious about granting an AI assistant broad access to email, cloud files, or other accounts when a narrower permission would do.
- Review an assistant’s proposed actions before approving them, especially if they send, change, or delete information.
- Verify consequential summaries and recommendations against the original document or webpage rather than relying on the assistant alone.
These steps reduce exposure and help catch mistakes; they cannot guarantee that an assistant will ignore every hidden instruction.
