No macro viruses but if your family lawyer uses some LLM-powered thingy in his workflow it might add a new dimension: prompt manipulation/injection attacks. A good spot to hide these would be at about ⅔ distance inside some wall of legalese at the beginning or end of a document since hardly anyone ever reads those.

Weeeell... Ya say that, but:

Many years ago someone "infected" my computer with a "manual virus": A printed-out sheet of paper placed on top of the computer, telling me to delete all my hard drive's files myself, then photocopy the sheet and put both copies on nearby computers.

It was obviously a joke. But in the "modern" agentic era, the same thing in a text file is slightly more realistic as a threat...
