We’ve also been blowing a lot of retainer hours just patching sites instead of building new features. It sucks. Ultimately going to cost clients more.
reply
Probably not, if you factor in the cost of security exploits. A single compromise can potentially sink the business.
reply
It's not like no work is happening though. Your clients are getting a more secure website. Maybe the bugs that are being patched would have taken longer to be exploited in the pre-LLM world but the bugs were still there.
reply
Most clients will not agree to pay extra for a more secure web site though. Unfortunately. Unless they’ve been bitten in the past, which most businesses still haven’t.
reply
Yeah you’re right but for most businesses increased security doesn’t lead to more sales.

I’m not saying that’s right, I’m saying that’s how a lot of businesses think.

Same here. I got access to Mythos two months ago, it confronted me with decades of nasty bugs I wrote. This has been stressing me out a lot, caused sleep deprivation (the bugs follow me in my sleep, yes, really). All other progress is halted, I've been squashing bugs day and night. I see a light at the end of the tunnel.

Bottom line: it's a good thing. My software will be better after that. Even if it's currently not good for my ego (and my health). But I'm glad for all the tools that help me improve quality.

And sure, I can just ask LLMs to fix the bugs, which works well half of the time, and produces bad slop in the other half. This is where human expertise and judgement is still necessary to avoid letting our code bases drift into LLM spaghetti hell.

reply
My question is, did it provide POCs? I have had some security issues flagged that I tried my best to exploit, but failed miserably. Since I do not have any kind of privileged access the LLMs I use have been unwilling to actually prove that it can be exploited.

While I did fix most of the things because while they might not have been exploitable they were bugs waiting to happen, in all but one case I haven't been very impressed by any of the LARGE IMPORTANT SECURITY HOLES that were found.

reply
No, the Mythos reports do not come with POCs. It's a lot of redundant prose explaining the bug it found (much more than I'm willing to read), it explains how it can be triggered, but doesn't generate actual exploit code.

But that doesn't matter for me. It shows me real bugs and less than 1% false positives. Some bugs are truly nasty and urgent, most are trivial and not exploitable at all, but they're bugs and so I'm fixing them.

Mythos isn't mythically superb for being the best LLM model, but only for not having these annoying guard rails that make all others randomly refuse to cooperate when you need them the most. Whoever invented guard rails - please stop! - they just slow the good guys down in the race.

It’s amazing how much slop humans have produced that now needs to be fixed by AI…
reply
Without all that slop how would you have trained the AI?

What makes you think that AI trained on slop is suddenly going to produce quality code?

reply
I think ai is more rigorous with testing. It’s not so much about what an llm “knows”, but more about how well it does plan-do-check-act.
reply
AI is as good as the prompt. It's a simple as that. If you don't foresee everything and anything that can go wrong AI isn't not going to magically fill in the blanks and save you. So in projects that already had good test discipline, well written specs and tickets and very clear expectations, coding guidelines and documentation it is relatively easy to fit an AI in for guided work. You still need to check up but chances are good that it will usually work as expected.

But any kind of mistake, any kind of ambiguity and you'll be in for a wild ride. It usually takes a while for the rot to set in. I've had to revert - more than once - to many commits prior to undo a bunch of work that had me completely puzzled as to what the reason that particular fork was taken to begin with. Usually I end up figuring it out but definitely not always. In some cases this kind of wild modification fed back on itself until the situation was beyond rescue. I'm a bit quicker with such reverts now than in the past, for the first year or so I would try to save what could be saved, now I just restore and try again.

But if you're not sharp when evaluating what gets done there is a good chance that you'll miss it and then it can pop up way later.

What I've noticed as correlation (but I'm not sure if that is the root cause) is that non-local effects and stack effects are particularly hard as is everything that requires a working model of the world.

edit: this comment seems to make people uncomfortable.

reply
I think the environment you set up for the agents is just as important as the prompt. I've been working full time on a claude code developed project for the last 10 months, and it seems to become better and better at developing the right thing. It has the tools to research whatever context it needs, test it's output in a relevant way, etc. It doesn't by itself suggest complete refactoring, or big performance optimizations, so that's something you have to prompt for, but it will collect all the evidence and context to make a proposal, implement it, and test it.
reply
I disagree that the prompt is the most important thing, I'd say other things like the model you use, a clean codebase, actually reading code and using discretion about which changes are accepted are far more important if you're using AI for work that needs to be correct. LLMs still make significant mistakes in design especially.

Harness, prompt etc etc are all peripheral IMO, though people like to think their super long prompt, custom harness and MakeNoMistakes.md skills are what contributes to their special skill with AIs, but really models are just improving.

You can just trust the AI to generate a perfect answer I suppose (and why are humans slowing it down at all if so?), but if you don't expect that yet you have to put in the work.

reply
Every single case of AI slop code I've encountered in a shipped product is a result of a complete lack of proper, professional workflow on the part of the human who decided to ship it. People are using AI as a reason to continue to justify their lack of responsibility for what it is they're doing.

And on the other side, I have seen AI produce exceptionally efficient, productive and effective code - the opposite of slop - when it is treated like a junior developer who will do any idiot thing, except when it is mentored by an actually experienced, professional developer.

The source of slop in AI code is not AI, its not the training data - its in the actual workflow of the human involved in its production.

reply
Yes, that I can agree with.

If you just turn it loose on a codebase and ship it when it passes the tests you're asking for getting burned.

reply
Interesting that this could result in net negative software productivity world wide in terms of features right now.

LLMs finding unpatched vulnerabilities faster than they can be reasonably patched, bringing all other software development to a halt.

That's only if you consider security to be unproductive!

If you consider it to be productive work, it's a massive productivity boon happening right now. Of course, product managers might disagree...

reply
Security work is not productive.

Imagine that the whole city has to install iron doors and window grilles, because wooden doors and glass windows are not safe enough anymore.

That's a lot of work, but is it productive in the end? Probably not.

With AI it's the same. World was fine with lax security approach before. Today it is not fine. Tomorrow we might need to prove every code line before shipping, will that be more productive? Hell, no.

reply
> Imagine that the whole city has to install iron doors and window grilles, because wooden doors and glass windows are not safe enough anymore.

Your imaginary scenario defines the solution to be pointless. If that same city was subjected to weekly riots smashing windows & doors, and people regularly died, stopping "productive" work to install things that keep people alive and productive? That's productive.

reply
It's a terminology issue. Economists use the term productivity in a certain way and they even use the term "broken window fallacy" to describe this debate.

https://en.wikipedia.org/wiki/Parable_of_the_broken_window

Basically, if you accept this line of reasoning, then someone going around breaking windows and someone else going around repairing them can be seen as good because it creates jobs. But that would be nonsensical and create poverty. That's why economists focus on wealth creation not job creation.

Fixing security bugs is only needed because people exploit them. It creates work but it doesn't create wealth.

reply
Fallacy applies only to incidental breaking of glass like child smashing window paying football.

Protecting yourself from bad actors also doesn't create wealth but it protects wealth you already have.

You know cybercrime and APT groups are not bored kids in their parents basement, there are groups that are running automated tooling to find vulnerable companies and if possible take all their wealth.

Just look at Binance of course, but if you are small company there are also people targeting those especially with AI assistance nowadays.

reply
> to illustrate why destruction, and the money spent to recover from destruction, is not actually a net benefit to society

it is distinct from question whether it is productive to defend from evil people

evil people + protecting from them is obviously net negative!

but it is not changing that of evil people are present then reasonable level of protection from them is needed, and setting it up is productive

reply
There is a sense in which productive is being used here that is slightly subtle. Security doesn't really add anything to net output. It is, in other words, a cost. That doesn't mean it isn't valuable.

One way to think about it is that production allows you to pay for stuff. Not necessarily directly but by way of trading. It is the output you use to buy things like security.

Consider an apple farm. What does the apple farm produce to pay its bills? Apples. They could also dedicate resources to pears, &c, and that would add to their production -- to the goods they produce, the goods with which they (indirectly) purchase tractors, fence posts, &c. They could also dedicate resources to security -- more fences, &c -- and this may even be prudent. Maybe thieves are getting taller. This doesn't really add to production, though; at best, it maintains production at the status quo ante (assuming the fence is effective).

reply
Just like securing a system is a trade-off, attacking one is too. Risk vs reward and time vs reward. Your personal blog doesn't need to be fort Knox, just patch it properly and you should be fine.

The point it, this was not happening before. LLMs made cheap cyber attack possible. But it didn't make the implementation of fixes correspondingly cheap. So now everyone needs to spend extra money/effort to install grills to cover where LLMs fall short.

For postgres, this absolutely makes sense though as long as people are willing to shell out the profits from LLM use to support postgres development. That is one way this could workout for everyone..

The physical world comparison is interesting. In the real world we have a small amount of security, but most things could be broken in to. Instead of fortifying everything, we just imprison the people breaking stuff.

Obviously this doesn't work on the internet since most hacking comes from overseas out of our control. Which makes me wonder if there is a possible future where we just block packets coming from countries that don't lock up the hackers.

reply
> Obviously this doesn't work on the internet

Not obvious to me. I am generally a fan of Cyberspace manifesto and the free Internet, I think it's great people can reach outside their ingroup and talk to strangers and ostensible enemies.

But, that doesn't mean we should give up physical security, the guarantee that the connecting party comes from a certain physical location (state, company). I think allowing connections from anywhere by default is fundamentally flawed security architecture, for certain things.

I don’t think North Korean hackers are attacking things from their North Korean IPs. They just buy a residential proxy. How would you prevent that?

The algorithm is: if the threat model is valid, there are vulnerabilities and you either have some software everybody knows about or a gang of hackers specifically targeting you, you should patch.

The part of the industry that profits from security theater will want you to patch no matter what, even if your business goes down in flames due to downtimes and new bugs introduced by patched components. They won't remind you to assess the threat model first.

By this line of thought building nice and usable UIs is not productive too, because users can learn cli tools (they did, DOS) and it costs less to develop them. And all the work in TLS/HTTPS has been wasted because HTTP is enough. And ssh vs telnet.

It becomes productive only once your business stops for days because somebody brought it to a halt by breaking into the servers and deleting them.

> In the rest of the world making sure your product works like it is supposed to is considered table stakes.

I don't think that's true.

In medicine, science often doesn't know how specific drug really is working. They just do a lot of tests and if these tests are positive enough, they ship it. I think it's good analogy. Biology is very complicated and it's out of our grasp to truly understand how various parts of it interact with each other on so many levels. But if something helps, it's stupid not to use it just because we don't fully understand it. Sometimes it bites. Sometimes it bites 30 years later. But we still follow that approach.

Software is similar. The complexity of the systems we build is enormous, when we're taking in account all the moving parts. I just read that someone emits radiowaves toggling memory bit and ex-filtrating information. How can you account for that? Probably you can't. But we still need software for good things.

reply
This wave is largely bugs found in pre LLM code. I'm sure there will be a smaller wave of bugs from llm code from the sonnet 3.5 - opus 4.7 era, and peeople will always write sloppy code/use dumber models under time or cost pressure, but since Opus 4.8/GPT-5.5 xhigh LLM code stopped being intrinsically worse than human code. At this point if you're shipping llm code that's lower quality than human code that's either because you don't have the money to spend on frontier models or because you actively choose a lower quality standard because of either various pressures or just not caring. if it's the latter your human code under those same conditions would also be really bad.
reply
Astra writes a lot of security bugs too, the upside is that if you also use it to review the output it will find a lot (most?) of them.

This is one of the least talked about and most useful features in any harness I would say, the review feature. I have never not found issues (either security or implementation) running it, no matter the code base or language.

reply
My job is seeing a similar deluge of security work and >90% of the bugs have been in pre-2024 code, and zero of them have been bugs introduced after we were first officially allowed to use LLM codegen.
reply
That could also mean the LLM is blind for the bugs it procudes itself. Just like any ordinary programmer would, on the job.

Theoretically yes, but empirically that's not the case. All models I've tried are really good at finding bugs they wrote themselves, especially in a fresh context.

Considering the software is much older than LLMs. Not many.

Also, in the article they mention a significant number of patches for older versions as well.

reply
Software is incredibly complicated. When you get into areas like security and networking and the internet its even more complicated. We rely on layers upon layers of software and hoping they are all done perfectly with no issues. The amount of junior devs, or outsourced devs for $10 an hour working on security relevant code is very very high, and always has been. LLMs if used correctly should be raising the floor.

An uncomfortable truth about the era of LLM code is that machine produced code is, on average, quite a bit more secure than human code.

Unsurprising to those of us that has been screaming from the rooftops that human code reviews were barely catching anything in your typical corporate environment. The majority of the value was pointing out missing tests, because breaking bugs got past human eyeballs on a regular basis, even in very good companies.

It's not that the LLM code is that great, but that many overestimated the human code and the human review.

reply
I think it's more likely to be the same as average human-written code; which is what they were trained on, after all.
reply
No it's far beyond average human code, and it's trained in RL environments on synthetic data etc now. The average human can't solve a millenium problem in mathematics but the LLMs are able to now. Anything with a verifiable output can be RLed on to make llms superhuman it seems, and the average human is not as persistent and thorough as e.g. gpt 6.1 sol at checking every edge case and hunting for bugs because that behavior is something that's just trained into the model. Frontier models perform farm above the average human at the categories of tasks they are RLed on like code and math.
reply
> The average human can't solve a millenium problem in mathematics but the LLMs are able to now.

I think comparing the resources they spent at it would be a more apt comparison.

AKA if you tasked 150 mathematics departments to only focus about that problem, and stop doing things like teaching and researching anything else, you might get close to the amount of resources that these companies put into solving the problem to get a press release.

reply
yet LLMs dont do off-by-one errors, typos mixing up variable names, interesting they seem unable to learn these human patterns
reply
They definitely write off by one errors. One of the first serious work tasks I used AI for a few months ago immediately had an off by one error.

What they are really good at is writing boilerplate and reading API documentation / example code. Avoiding subtle errors is not what they're good at in my experience.

reply
I've seen both of those (and others besides). I don't know how much code you've looked at but your negative directly contradicts my experience. Review that code. All of it. Be super critical because it looks good but that doesn't mean it is good. Those are two entirely different things.

Also: most tests are positive tests. Tests rarely observe the negative space: that which is there but shouldn't be there.

reply
Do you mean "created" as in LLMs were used to discover existing vulnerabilities, or as in LLMs wrote unsecure code? If it's the latter, then the answer probably is "very few". Frontier models have been better than the average programmer at writing secure code that follows up-to-date best-practices for some time now.
reply
Depends on the layers you are working on. Security is top priority on a lot of things that are visible to the internet, but in a lot of large companies, the footprint of the whole org is so much larger that than, and there many companies are deferring many security issues. So then you see a lot of speed there, when the consumer accessible systems are the focus of the security push.
reply
Hopefully with the amount of visibility LLMs are bringing to the situation, security will finally be considered a first-class feature
reply
LLMs will likely greatly increase the cost of ignoring security, which is the most powerful tool to increase security ticket prioritization.

I wouldn't be shocked if in 1-2 years non-security vetted software released into the wild will be hacked on arrival, like Windows XP without service packs used to be.

reply
Personally I think LLMs did only produce garbage code. Not coincidentally, the same upgraded LLMs that have gotten so good at finding bugs are also much better at not writing bugs. Especially if you make them review their own work. They still have a hard time with code design, though.
reply
That is not the take-away. LLMs are finding potential bugs in code. People are using LLMs to create potential fixes which people then test, confirm and implement.
reply
Disagree. The takeaway is that software is much harder to write correctly and securely than almost everyone has internalized. The amount of vulnerabilities released in the past couple weeks makes me think writing software by hand will soon be not only uneconomical, but mostly irresponsible.
reply
> makes me think writing software by hand will soon be not only uneconomical, but mostly irresponsible.

Human-written code isn’t inherently buggy, and LLM-written code isn’t inherently bug free. What is irresponsible is shipping code you don’t understand, and that will only increase with LLM-written code. A major reason why so much of the world’s software sucks is precisely that we think of it in terms of what’s “economical” and not what’s good or right. What we need is to slow the fuck down and stop treating every facet of life like a transaction. Software is filled to the brim with dude bros who “move fast and break things” and actively exploit people as their business model and somehow are called “the brightest minds of our generation”. Our priorities aren’t right.

Escape to where? It's not as if there's a lot of idle compute capacity sitting around.

And even if the impossible occurs and LLMs hack everything that's connected to the Internet, so what? That would be inconvenient but it wouldn't cause doom. People would muddle through and eventually fix the critical problems, just like they always do.
