Hidden text can undermine your AI [Brainyacts #268] — from thebrainyacts.beehiiv.com by Josh Kubicki

What if one line of invisible text could change how your AI interprets an entire case file?

This isn’t hypothetical. It’s called prompt injection, and as more legal teams connect LLMs to client files, discovery docs, and contract repositories, the risk is growing, fast.

The AI, following instructions like a good little pattern matcher, now refers to the entire thing using the wrong legal frame.

You never saw the white text.

Your associate didn’t catch it.

The system happily processes it as truth.

And now you have slop in the system. Not because the AI hallucinated but because it was tricked.
