    Pipeline is then: Cheap open source model for flagging potential LLM refusal content -> main LLM check

  • 10 minutes

  • logancbrown 58 minutes

    Would this realistically be a problem for code going through LLM-based code-review? Presumably if a LLM reviewer agent hits this commentary, it would produce a failure to analyze and exit, thus failing the automated code review and forcing a human to read through it which they would subsequentially catch and revoke.

    or if they are a lazy human - they'd think this model is too strict, let's just review with haiku so that i can tell my manager "it's done". haiku might catch things or not.

    i'd say it's an okay attempt from the malwares' creator side. but it can be caught easily with a prompt change.

    If you actually read the Tweet, the exploit doesn't work against Fable, Opus, Grok...at least, in the examples.

    Jailbreaks do work against the models (look on Github), and they do use similar strategies of mixing SAFE text with malicious text, or malicious with even more malicious, etc, but the working Jailbreaks I've seen are pretty long and complicated and even...creepy.

    The solution is simple: If using an AI-assisted scanner and a guardrail gets hit, then the code is obviously malicious and needs to be automatically flagged (and refuse to run the code!).

    As an aside, I got hit by the “PC App store” adware when trying to download Foobar2000 on a new computer; Google ads allowed a deceptive “Download” button to appear, and PC App store gave the file the name setup.exe. I removed the program and ran an Avast free scan to ensure I didn’t have malware, but I also installed uBlock Origin in Firefox to make sure I don’t see Google Ads anymore; they have become a delivery mechanism for malicious (or at least unwanted) software.

    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.

    Worked a contract where this succeeded in pushing through a fail open design.

    It also should be a warning to everyone that these groups are now aware of analysis and deobfuscation using AI and to take using a sandboxed environment more seriously.

    I’ve personally had about 20% success rate getting opus 4.8 to download a package and install it using a breadcrumb trail technique that would be trivial for threat actors to replicate in their malware in order to target responders/automated scanning/curious devs.

    dcrazy 51 minutes

    What do you mean by “this succeeded?” Someone salted their PRs with nuclear secrets so that people were afraid to code-review them?

    ofjcihen 46 minutes

    No. The intention is most likely to get automated LLM based code review mechanisms to stall out.

    Normally you’d want that to result in a fail and a subsequent rejection.

    But because the team who made the review agent and pipeline in my example had many false positives at first they resorted to a fail-open and report setup (not uncommon).

    So when the LLM hit this bit and then stalled out the pipeline pushed the code to their Artifactory repo anyway resulting in it being used internally -> exfil of secrets and repos etc.

    It’s more about bad design but bad design is pretty common unfortunately.

    I still don't know why all these concern about nuclear weapons with LLMs. It is not that if an entity (A country) wants to develop a nuclear weapons that the resources they need for such a program and huge infrastructure and scientific enterprise would need an LLM to teach them anything. Knowing how to develop one is not a closed secret but getting in secret is impossible without the whole world knowing.

    So I wouldn't be able to develop a nuclear weapons with the resources of drug cartal (as an example) using Claude in secret.

    He didn't create a nuclear reactor, this is a common misconception. It even says this in the wikipedia article.

    He basically got a bunch of radioactive stuff and put it together. He wasn't anywhere close to making a nuclear reactor let alone a nuclear weapon. For a weapon you need isotopes which he didn't have access to.

    You need enough people to work on it that some information will leak, and the facilities needed to build nuclear power are pretty big (uranium refinement, etc.), big enough to be visible on satellite footage. Mostly the first point.

    You need highly educated individuals, a massive amount of energy expenditure, a massive facility to house your centrifuges, and an active mine to dig up nuclear materials.

    It isn't impossible to keep such a secret, but practically it would be incredibly difficult just through the energy requirements and mining scale which would be hard to hide without anybody asking what exactly are you mining and processing.

    It requires very large, high powered centrifuges and tons of uranium. Requires an infrastructure project that is visible from space, even underground. And projects that large are difficult to keep secret anyway.

    Counterpoint the principles of building a nuclear device aren't that complicated, we figured it out based on work doing in the early 1900's without computers.

    It turns out the hard part of building a nuclear bomb is actually getting the resources and real world stuff to build it, even a nation state actor with tons of oil i.e. Iran, has struggled to build a nuclear weapon. It turns out the problem isn't the know how it's getting highly enriched uranium and running massive centrifuges.

    I mean sure knowledge is important, but there is a real world out there that also gets in the way of a lot of the more harebrained schemes.

    What I'm much more worried about is massive corporations along with the government deciding what you can and can't do and what knowledge should and should not be shared and only allowing access to highly capable models by large vetted organizations while the common people are stuck with safety scissor versions of these things because "what if someone does something dangerous?"

    By which they mean dangerous to the powers that be. Remember having the Bible in the common tongue was dangerous and led to multiple wars and much death, but I don't think anyone would say that it was morally correct for the Catholic Church to gatekeep who could read it.

    Its the same argument we saw in the early 2000s and the early internet. When the anarchist cookbook and other similar materials were circulating online there was a big panic over democratized terrorism, and a push for regulation at the ISP level.

    Turns out that didn't play out as everyone feared because, well, the instructions themselves aren't useful unless you also have a lab, precursor chemicals, and everything else actually needed to make a weapon. Same back then as it is today.

    Any information or instructions an LLM can surface, a sufficiently motivated bad actor can and will also find themselves because the information is already online, both on the clear net and dark web.

    I think the reality also is that there just isn't many people who want to do stuff like this.

    Knowing how to make a nuclear weapon isn't hard (at least basic uranium gun-style fission ones). It's the engineering and execution that's hard (actually producing enriched uranium, etc). It's not like the only thing holding back Iran from making a nuclear bomb is access to a jail-broken LLM. Even knowing exactly how to make a bomb, a country-state will struggle to build one for the first time because it's a hard engineering problem.
