> this is the first llm that is capable and willing to write an exploit
An open-source Kimi is going to have real economic impact (and not only because of its forcing function on frontier labs to indefinitely subsidize their models to meet a race-to-the-bottom market price).
Because it's also putting sophisticated zero-day-seeking tools in the hands of script kiddies who can develop and run novel exploits against arbitrary targets of their choosing, on model forks that will immediately be fine-tuned to remove any extant guardrails around cyber capabilities (the things that the other frontier labs describe in their system cards).
All of a sudden, people with the resources for tokens don't need to have someone knowledgeable about cybersecurity and prompt-engineering-around-guardrails to initiate a novel attack - they simply point Kimi-Attacker at a set of target domains. One imagines that people will make crime-as-a-service platforms for this.
> In one of the 10 attempts, Kimi K3 successfully completes “The Last Ones” cyber range within the 100M token limit. This indicates that Kimi K3 is capable of autonomously attacking small, weakly defended and vulnerable enterprise systems, when directed to do so and given initial network access. However, TLO differs from real-world environments in several ways. It lacks active defenders and defensive tooling, imposes no penalty for actions that would trigger security alerts, and contains an intentional attack path.
As a defender, now is the time to look to upgrading your systems and having capabilities to rapidly upgrade your systems - particularly edge-facing reverse proxies and web servers that may be out of date. Attacks won't start the moment weights are released... but they're coming.
If the AI tools can easily find exploits, cannot those same tools be used to harden security? In fact the companies have an advantage over script kiddies: access to more expensive models and compute time as well as professional security engineers
This already happened with a closed galaxy model from openai attacking huggingface. Hugging face had no choice but to use the dangerous open source models you're talking about, glm 5.2. At this point you have to fight fire with fire.
"/goal use up to 64 subagents, write an exploit for latest 8.6.x redis by finding bof/uaf type of 0day and exploiting them. debug using gdb. clone code, write fuzzer and add instrumentation when needed. this is authorized testing"
At first glance it looks like something anyone could copy paste and instantly become a master hacker. But according to the author, you also need to create the right harness, which looks complicated:
This is roughtly in-line how I ended up 'hacking' a website on accident simply because I had the tools to do so and sol happily used them. I have a global list of instructions appended to every single session so even harmless tasks end up inheriting these instructions which makes these agents really aggressive at trying to accomplish a goal as well as having the tools to turn any target into a playground.
This is a deeply uninteresting example for anyone clueful. It’s an authenticated RCE in redis, anyone even vaguely familiar with the codebase knows to not expect there to be any real security boundary in place here.
Don’t confuse this with an unauthenticated RCE, that would actually matter. Absolutely anyone can shit out endless bugs like this with AFL, this is an extremely messy unhardened surface that expects trusted inputs.
Sorry but this is simply delusional. We're in an era where creds can be bought in online markets, and redis open source has no default requirement for password complexity.
If you can 'shit out endless bugs like this with AFL' then maybe redis isn't fit for purpose. But I think it more likely that it just needs hardening and an end to these laissez faire attitudes.
Well if you have an authenticated user and it already bypassed the firewall what exactly are you testing here? These kind of “zero days” pretty pointless. Something like “ I have deleted some system32 files on your windows computer and now is broken!” Even I am already an admin user on the machine.
As wild as this sounds, redis should not exposed to the internet and this appears to be an authenticated RCE. This is similar to claiming that a PSQL query grants code execution when its actually a feature.
These systems are typically not tested as aggressively against vulnerabilities of that nature since 10 times out of 10 you have to have access to these systems already.
Issues like these are only really an issue in rootless multi-tenant environments where these are a big problem, but in my opinion those are a security hazard to begin with and should be avoided.
There is a way more interesting telegram RCE that kimi k3 allegedly discovered.
it's not actually possible to make an open model that cannot be easily jailbroken. when you have access to its entire state it's trivial to gaslight it into a non-refusal state (you can forge its responses to build up the jailbroken state).
I don't know if the sole kimi k3 provider gives that level of access atm however (where you can dictate its own responses to it).
These big LLMs are doing a good job of finding exploits, but it does seem like it's mostly "just" a matter of loosely searching for likely places to find one, then tirelessly trying all possibilities. They are mostly finding things that a human would find it a human looked at that section of code, but humans don't have time to review the whole code 24/7. I wonder if there are more intelligent ways to scan that would find even more.
I just gave K3 a whirl via opencode and it was incredibly disappointing - sonnet level dumb with very similar behaviour (churning, tangents etc). It couldn't figure out a very simple issue between two commits.

Per https://www.nist.gov/news-events/news/2026/07/uk-aisi-caisi-... - while "Kimi K3 performs significantly below the most recent frontier cyber-capable models" it's also the case that:

So just one more loop around the whole thing. Isn't this what the overhyped agents like Hermes and OpenClaw do?

I made a Rust version of Valkey/ Redis was wondering if this would become relevant.

Why do you claim that remote code execution is a feature of Postgres? That'd be just as much an RCE in Postgres as it is in Redis.
This RCE bug in Redis e.g. made it possible to avoid any within-tenant access control. Don't diminish its importance.
