So this is what they meant when they said that thanks to AI even silly grandmas like me can be a hacker! I still remember how to change font colour and size in Word, time to earn billions of dollars 💰

I dont use Microsoft Word
Is this basically clippy asking you if you want to write a letter, but with prompt injection?
An attacker places hidden instructions in a document that is later used as source material in Copilot for Word. Copilot may interpret those instructions as part of the user’s request, causing it to manipulate the document being drafted or edited. Copilot may then also copy the hidden instructions into the resulting document, turning that document into a new carrier.
Its Bobby tables all over again! Sanitize your inputs please.

wait, is this real?
It would seem so: https://www.theregister.com/security/2026/07/29/word-worm-crawls-into-copilot-spreads-chaos/5280588
It makes sense: with LLMs and agents based on them, even plain text becomes effectively executable, so any document can carry malicious instructions. It's worse with complex document formats like DOCX, ODT, or PDF, since text can be hidden from the human eye and escape detection by review. Very risky tech...
