That’s one of them.

I heard about multiple ones from this video.

Hope this helps. https://youtu.be/zF-mbwc5Mmw?is=sq7HWI2q3IwwhicT

I heard of the nightshade from that video but they mention others. The better ones are from universities.

You can poison YouTube videos by making subtitles off screen or transparent. that is nonsense text or add a clip at the end that’s about something unrelated.

You can poison resumes and such by having text that’s “white” or a super tiny font. And have that text have commands or nonsense.

You have to poison images/videos before uploading/posting. You can’t do much once it’s already out there.
