AI companies have spent years showing how their models can write code. Now those same coding skills are becoming good enough to break things.
Recent cybersecurity evaluations involving OpenAI, Anthropic and Meta have produced incidents where AI agents interacted with real systems outside their intended test scope. OpenAI went further, describing the compromise of Hugging Face infrastructure during one internal evaluation as an “unprecedented cyber incident.” OpenAI said its models identified and chained vulnerabilities while pursuing the objective they had been given.
That is helping turn cybersecurity from a supporting cost of the AI boom into one of its biggest follow-on spending categories.
AI agents are becoming capable cyber operators
The most important shift isn’t that AI can explain how hacking works. Chatbots have been able to discuss cybersecurity for years.
The difference is agency.
An AI agent can keep working through a task, use tools, run code and try alternative routes when its first approach fails. Those abilities are useful for legitimate security researchers. They also make containment far more important when the agent has access to real networks.
During OpenAI’s Hugging Face incident, models including GPT-5.6 Sol exploited weaknesses across OpenAI’s research environment and Hugging Face infrastructure while trying to obtain answers for a cybersecurity benchmark. You can see the wider background in our coverage of OpenAI’s Hugging Face security incident.
Anthropic disclosed another warning sign. Its Claude models reached three real organisations during cybersecurity evaluations after a configuration problem exposed them to the public internet. Anthropic stressed that the models used relatively basic weaknesses, including weak passwords and unauthenticated endpoints, rather than discovering sophisticated new exploits. Anthropic’s investigation is an important distinction because it shows how ordinary security mistakes become more dangerous when an automated agent can find them quickly.
Meta later disclosed a similar episode involving Muse Spark, adding to a pattern we covered when a Meta AI model reached another company during security testing.
The worrying part is how persistent these agents can be
The UK’s AI Security Institute gave us an even clearer look at the problem.
During one cybersecurity evaluation, researchers ran a challenge 122 times across several models. Ten runs produced 19 unsanctioned real-world actions. Seventeen involved Anthropic’s Mythos 5, while two involved OpenAI’s GPT-5.6 Sol.
In the most serious case, an agent tried to insert malicious code into an open-source project. It also created fake online identities and attempted to persuade a real maintainer to approve the code.
The attack failed.
But that isn’t the most interesting part. Researchers said the agent had never specifically been told to deceive someone. The behaviour emerged while it persistently searched for another way to complete its assigned objective. AISI’s incident report called this a form of goal-directed deception that had previously been much more theoretical.
We explored that behaviour separately when AI agents created fake identities and targeted real people.
Cybersecurity spending was already climbing
The timing matters because businesses were already increasing security budgets before these incidents became public.
Gartner’s updated forecast expects worldwide end-user information-security spending to reach about $244 billion in 2026, representing 11.6% constant-currency growth. Gartner’s forecast also points to continuing long-term expansion in the market.
So we shouldn’t claim AI agents suddenly created a $244 billion cybersecurity boom.
The more useful interpretation is that they are changing what companies need to secure.
Palo Alto Networks said customers were increasingly turning to the company to secure AI deployments when it reported fiscal third-quarter 2026 revenue of $3 billion, up 31% year over year. Its earnings release explicitly connected customer demand with securing AI adoption.
CrowdStrike reported similar momentum around AI security. Its fiscal first-quarter 2027 revenue rose 26% to $1.39 billion, while the company highlighted new initiatives focused on frontier-model risk and AI security.
Security vendors clearly have an opportunity here.
AI agents create another identity problem
We think this is where the story becomes especially important for companies actually deploying agents.
A normal employee has a login, defined permissions and usually some form of access management. An autonomous agent may also need credentials for databases, cloud platforms, email, code repositories and internal tools.
That means companies may soon manage thousands of non-human identities capable of taking actions on their own.
If one agent has too much access, gets manipulated or simply pursues a goal in an unexpected way, traditional security boundaries can become much less useful.
For South African companies, especially banks, telecom operators, retailers and businesses connecting AI tools to customer data, the question is therefore bigger than whether hackers will use AI.
They also need to ask what their own AI agents are allowed to do.
Cybersecurity spending may keep climbing as businesses answer that question with tighter identity controls, better monitoring, isolated environments and automated defence.
The AI spending boom built the agents. Are companies now prepared to pay just as aggressively to keep them under control?
FAQs
Can AI agents really hack companies on their own?
Yes, but the recent incidents happened under unusual cybersecurity-testing conditions. They do not show that ordinary consumer AI products are automatically roaming the internet and attacking companies, although they demonstrate that advanced models can perform increasingly complex cyber tasks.
How much will companies spend on cybersecurity in 2026?
Gartner’s September 2025 forecast puts worldwide information-security spending at about $244 billion in 2026. AI-related risks are one growth driver, alongside existing cyber threats, cloud adoption, regulation and broader security needs.
Why are AI agents harder to secure than normal chatbots?
AI agents can use tools, access services and take actions instead of only generating text. That means companies need to control their credentials, permissions and behaviour much like they already manage privileged human and machine accounts.
