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.
"/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.
Congress shall make no law.... does Congress really make laws anymore?
...and to petition the Government for a redress of grievances.
Petitions go unheard. The Government is too big.
That said, we are now living in a global world with instant communication and the boundaries of wrong-think and word-violence are now blurred to the point that people can cast spells using magic incantations that allow for violence.
The people who believe in the 1st were those who thought "sticks and stones" but today words can hurt more than feelings.
I would be most pleased if all profanities and aggressive wrong-words were voted or listed so that we can speak freely without inadvertently offending the wrong group who has the power of the sword.
> 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.
This is a concern but given its size, it's also going to cost a potential user $500-600k in hardware to self host and run Kimi K3 at any useful speed with full context size. It's not something that just anyone interested in attacking a system can use.
The size/cost of hardware is far beyond even something like a self-hosted GLM5.2 Q8 at approx. 850GB GGUF file on disk size, which can run at a slow tok/s rate on a server with 1536GB RAM.
It remains to be seen once it's released, let's say theoretically unsloth quantizises it to their own version of Q8-XL, and it's 2TB in size. But we don't know what speed it will run on a dual or quad socket xeon server with, let's say 48 * 64GB DIMMs, 3TB of RAM. Enough room for the model and its full default context size. 10 tokens/s? What kind of speed will it run at when context fill is 200,000+?
The ability to run it fast enough to go on a recursive nested attack of finding an entry point into something and then proceeding with lateral movement/privilege escalation and such will require more speed, like 40-50 tok/s at least, unless you're prepared to wait weeks.
Same that some people are right now running GLM5.2 in its 850GB version on CPU-only and a pile of DDR4 or DDR5 server RAM, yeah it runs, but not very fast. Good enough to give it "build this piece of something and wait a few hours" tasks, come back later and see what it's done. Yeah, you can do that under $20-30k for sure. Even with something like a used Dell R940 with 1536GB RAM bought on eBay.
I'm pretty sure the difference is, by definition, whether they're just using tools other people built or they actually understand things and can do it themselves. The script kiddie can be incredibly dangerous if the tool they grabbed off the shelf works.
Do you think any programmer really understands how their program works end-to-end? At some abstraction layer, we're all clueless. There are many layers between what you type into the text editor and the actual CPU ticks that make your program work. I bet nobody fully understands the whole stack.
Now that that text editor accepts English, we're all calling each other names, etc.
Used to be, knowing a ret from a nop (90) meant something. If you can just load up a model and say "hack teh NSA.gov" while not actually knowing anything about even DNS, what are we even doing?
This is exact same difference as between junior and senior engineer.
The premise now is that everyone and your mom can vibe code next unicorn during a lunch break using the latest llms, but the difference between a rookie and a seasoned programmer is that the later can navigate the model in much more efficient way, understand the code that has been written, and notice hallucinations on the spot.
Completely agree. This is how I feel towards the OpenAI hacking of hugging face. Even if it was script kiddie stuff now anyone can automate that with ease. It certainly cuts both ways and people who are still ai skeptics need to wake up to that. You’re going to need these systems to defend yourself
Of course, it's impossible to know for sure what was LLM processed or not, but some of your posts (like this one) have been getting classified that way.
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.
No, that’s a flawed analogy, because this is an RCE. It's (like) having credentials for a network service, then exploiting that service to execute arbitrary code on the Windows host (of course the blast radius depends on the underlying permissions). Access to Redis is not access to the underlying server.
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.
Sad side of this is that decision makers are seeing these and think that AI can replace yet another department in their office.
I just saw a nice presentation from SecFest from a guy who ran a red team, but now they pivoted to basically anything and will be more than happy to fix your car if that would pay their bills.

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

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:

if Kimi is around 1-3tb big, even current DDR5 prices are at 15k.

Imo this differentiation is totally pointless now. It gives everyone with access to AI the ability to use it as intended but also otherwise.
But that is true for the defensive side also.

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