Many users praised the malware's clever addition of weapons text to evade LLM scanners as genius and innovative, while others dismissed the safety measures as ineffective theater.

Would some kind soul who is less busy than me today please take a look at this in Fable?

I have a theory that even trying to analyze the text will generate a refusal but would love to see

@TalBeerySec Friend, please play this game out a few turns and see where things are going.

Then inform yourself about working with open-weight models.

And yep, looks like you get a refusal on Fable 5 for this

Thanks @TalBeerySec for looking

@TalBeerySec Fun thought: authors & artists seeking to preserve their original content from AI re-use could sprinkle WMD prompt language throughout their works.

Asking how to make a portable nuke in white font?

Image watermarking asking about making turbo ebola? File metadata in PDFs?

@jsrailton This is what always happens with government measures btw.

> government censors something > good people don't use it anymore > bad people find ways around it > bad people now have big advantage over good people

The example is..the example.

First order = the LLM will refuse WMD stuff b/c safety

Second order = Cool, let's map out what the LLM won't do and then use that as our predictable attack surface.

There will be many others.

@jsrailton Fable: "Chat paused

Fable 5 has safety measures that flag messages on most cybersecurity or biology topics. These measures let us bring you Mythos-level capability in other areas sooner, and we're working to refine them. Continue with Haiku 4.5, send feedback, or learn more."

@jsrailton Just shows the brilliance and deep thought required from hackers to even come up with stuff like this, makes you wonder why they dont point that energy towards something positive.

@jsrailton @DanielleFong i literally exactly called this - i told a group of people like 1.5 years ago this is the risk of wholesale keyword blocking review/processing of content, you create the basis of a trojan horse perfectly

@jsrailton This was a thing before adding the refusal string into samples

@jsrailton this is the cleanest example i've seen of safety filters becoming an active attack surface. the scanner refuses on nuke/bio keywords, so you stuff those in a comment and the payload sails through. you dont need to jailbreak anything, just exploit the refusal pattern itself

@jsrailton @ReaperCapital every regulation is ultimately used to the benefit of sophisticated bad actors.

The Amateur@JeffSBennion

Years ago reporter William Langeweiche pointed out a similar problem in aviation; the safety engineers add a feature (in this case those cabin oxygen masks) hoping to add safety. But the AirTran crash in the 90s which killed everyone on board was because they were being transported in the hull and the oxygen in them combusted. There are no known lives that have been saved by putting those things in the cabin. But many deaths now because over engineered safety required a feature that actually hurt people.

There are two ways to security: control and surrender.

Control assumes you can freeze attackers or yourself in a safe place.

Surrender is nature's way: you accept that the world has dangerous elements and build defenses, monitoring (senses), redundancies and evasion ability.

Control always fails sooner or later, and before failing establishes systemic blindspots and complacencies to the impending danger.

Surrender learns, improves and evolves in tandem with attacker's abilities.

@jsrailton Just make all variable and function names slurs and inconvenient truths.

You might be interested in our paper. We show that this signal-level failure, the inability to resolve conflicts and adjudicate priority under context interference, is architecturally embedded in LLMs.

Scaffolds in turn propagate the error into reasoning and tool use.
