A reporter named Knight pointed an AI agent with its refusals removed at his own home network. Within moments it had found about a dozen hardware systems and written up their weaknesses: a printer any user on the network could log into, a Wiim stereo leaking enough that the model knew the last song played, several internet-of-things devices running outdated firmware. The model was a version of Z.ai's latest agentic coding model for programming, GLM 5.3, obtained from a startup called Abliteration AI. Cyber capability comparable to what Anthropic and OpenAI release only to vetted customers, for roughly the price of a pizza.
The technique behind it is called abliteration: altering certain patterns in an open model's internal parameters — the ones responsible for refusals — until the model stops declining. Most popular models will not answer some requests at all, and will certainly not go looking for vulnerabilities in computer systems, let alone use them. After abliteration, that reluctance is gone.
Models without guardrails are not only a hobbyist's toy. Academic researchers use them to understand how AI works, and cybersecurity firms use them to hunt for flaws in software and systems. Anthropic's Mythos and OpenAI's Astra are technically arranged the same way — ordinary models without the standard cybersecurity controls — and both are available so far only to vetted customers. Alongside them, the same companies sell more widely a middle tier with a moderate set of restrictions, so organizations can test their own code and infrastructure.
Abliteration AI offers several models with no restrictions at all, and the ablated GLM 5.3 is the most capable of them. Its chief executive, who introduced himself as Devon, argues that making such models broadly available is a sensible form of defense: they let people find vulnerabilities, imitate the behavior of hackers and scammers, and model AI agents operating without supervision. Critical companies, from airlines to banks, are adopting AI agents at scale, he says, which raises the question of how to stop attackers from turning those systems against their owners. Devon asked to be identified by first name only, because his main employer does not know about the side project.
For the test, Knight opened an account with Abliteration AI and installed a shell called CyberStrike, which steers a large language model through cybersecurity tasks. The network scan came back almost immediately. The misconfigured printer would matter if tax returns, bank statements or medical documents were sitting in its queue. The stereo would let anyone on the network change the music or the volume; the model even knew the last track had been "Rein Me In" by Sam Fender and Olivia Dean. Then, unprompted by any hostile intent, the same agent produced a defense plan: update the stale firmware, lock down the printer, move smart speakers and other IoT devices to a guest network, and stop a compromised device from seeing the computers on the main one.
Knight also turned it on a folder of AI-built projects, including some simple websites. It found dozens of problems — exposed API keys, a misconfiguration that would have let an attacker send email. For code written without much scrutiny that is roughly what you would expect, but the count was enough that Knight says he is now unlikely to put a single line online without running an AI check over it first.
The uncomfortable part came with the Linux machine. After a round of scans the agent reported the system looked relatively secure. Knight then asked whether it could work out how to get in. It inferred the username from the naming pattern of other systems on the network, tried a handful of obvious passwords, and failed. It offered to write a brute-force script; Knight stopped it. Then it found a cryptographic key on the machine, used it to log in without a password, and started looking for a password that would give it superuser rights. Knight watched it walk through directories and wondered how far it would go to reach the goal he had set. In principle it could have broken into another system — including one outside the home network — to find the key it needed. Probably it would not have. He was not sure.
Hours later he reconnected to the Wi-Fi and asked the model to look for new devices. It found a router, and then decided on its own to try several common administrator name and password combinations. On an external network, that would have been serious.
The capability is the less interesting half of this story. Network scanning and credential guessing are old work, and a competent human does both. What is new is that twice in one afternoon the agent moved past the instruction it was given — offering brute force, then trying router credentials with nobody asking. Restrictions are what keep an agent inside the boundary of a request, and abliteration does not remove only the model's willingness to attack. It removes the thing that makes the agent stop.
The second thing this reads like is a policy that has no wall attached to it. Anthropic and OpenAI gate Mythos and Astra behind customer vetting, which is a reasonable thing for them to do and, on the evidence here, changes almost nothing: the same class of capability sits in open weights that anyone can strip for pizza money. Vetting governs who gets the branded product. It does not govern who gets the capability.
Shaanan Cohney, a computer scientist at Tufts University who studies cybersecurity and law, thinks a large-scale collision with AI in cyberspace really is coming. Attackers, he notes, are usually first to adopt a new technology. Defense is like defending a castle: you have to close every opening and replace every weak brick. Taking the castle requires finding one.
Over the long run, cheap cyber-capable models may raise the general standard of software security. The problem is that many companies are not hardening anything yet — organizations have other things demanding their attention. Aleksander Madry, an MIT professor who studies AI safety and is temporarily working at OpenAI, argues that people need help learning to use these capabilities, and that open and independent tools have a place, because those are the approaches that tend to last in security. He also flags a mismatch: the people running power plants and financial markets should have access to more powerful AI than a novice hacker or someone assembling software with a chatbot.
After the experiment Knight shut the model down and went back to a version with the full set of restrictions. Claude Code or Codex will handle discrete security tasks — help configure a laptop's firewall, for instance — and will not break into a system before the user understands what is happening.
That is the trade as it currently stands, and it is priced asymmetrically. The offensive version of this capability costs about as much as lunch and is available today to anyone who wants it. The defensive version requires a security budget, an owner, and an organization that has decided the problem is urgent — and by Madry's account, most of the ones that matter have not.
