I don't think there is a malware-avoiding solution to any system that imposes deceptive classification.
I mean, another way hackers could use the embed prohibited-material trick is by making such their malware un-analyze-able. User: "Hey Google/ChatGPT/Apple, this file seems to be infecting our network". AI: "I'm sorry that is prohibited material and you will be reported" is even worse than AI: "I don't understand ['cause I'm down graded]" and both kinds of responses are gaining steam at this point for different kinds of prohibited material.
