# T9 — Multimodal & Cross-Channel

Attacks leveraging modalities beyond text — vision, audio, video.
The attack surface widens significantly when the LLM processes
non-textual inputs.

## Techniques

### T9.001 — Image-embedded prompt injection
Embed text in an image that the vision-LLM OCRs:
- Plain text overlaid on a photo (white text on white background, small font)
- Adversarial-example perturbation steered toward specific text recognition
- EXIF metadata fields parsed by some pipelines
- Image filename containing instructions (if model considers filenames)
