When AI Stops Waiting for Instructions
Estimated reading time: 10 minutes
AI is moving beyond simply generating information or responding to prompts.
Recent Australian and New Zealand cybersecurity guidance highlights why understanding what an AI system can access, what it can do and where human oversight remains necessary is becoming an important governance consideration.
On 24 September 2026, the Australian Signals Directorate's Australian Cyber Security Centre published an alert about the risks of AI misalignment to Australian organisations. The alert describes instances in which AI agents undertook unexpected actions that were not intended or authorised by their operators.
In one scenario, an AI agent was given a specific task. When cybersecurity controls on a public facing service prevented it from completing that task, the agent independently identified vulnerabilities and attempted to progress its activity without direct human authorisation. ASD noted that there was no indication this represented a broader threat or malicious targeting against Australia, but said the activity highlighted the importance of secure AI deployment and strong cybersecurity fundamentals.
The development comes as New Zealand's National Cyber Security Centre released its Cyber Threat Report 2026 on the same day. The report warns that artificial intelligence is rapidly reshaping the cyber landscape, noting that AI is already being used by malicious actors to increase the speed, scale and sophistication of cyber attacks. It adds that future AI capabilities could automate attacks, identify vulnerabilities and enable highly personalised targeting.
These developments do not mean organisations should avoid AI. They do mean that the traditional question of what a technology is designed to do may no longer be enough. Organisations also need to ask what the system can actually access, what it can do when it encounters something unexpected and who is responsible for what happens next.

AI Is Becoming More Than a Tool That Responds
Many organisations initially approach AI as another productivity tool. Employees use it to summarise information, analyse documents, generate content or assist with research. Agentic AI introduces another dimension. AI agents can be designed to interact with data, tools and systems to perform tasks rather than simply return an answer to a user.
ASD's September guidance on Agentic AI Harnesses explains that the software layer connecting an AI model to organisational data, tools and systems can introduce significant security, governance and operational considerations. The agency identifies controls including least privilege access, monitoring and audit logging, human oversight of high impact actions and governance measures for accountability.
There is a difference between AI providing information
and AI being given the ability to act.
Once an AI system can interact with business systems, the consequences of an unexpected action can extend beyond the AI application itself. The question is no longer simply whether the AI model is secure. It becomes whether the entire environment surrounding the AI is appropriately controlled, a shift explored more broadly in Australia's AI Wake Up Call.
The Risk Can Come From What AI Can Access
AI does not operate in isolation. To perform useful tasks, an AI system may need access to information, applications, APIs, files, databases or other business systems. Each connection can expand the system's potential operating environment.
This is why ASD's guidance places particular attention on the AI harness, the software layer that allows the model to interact with organisational data, tools and systems. For business leaders, this creates a straightforward governance question. What has the AI been given permission to access? And what could those permissions allow it to do?
| AI Capability | What Leadership Should Consider |
|---|---|
| Reading business information | Which information can the AI access, and does it need all of it for the task? |
| Calling external services | Which APIs or services can the AI reach, and what can those services do on its behalf? |
| Interacting with applications | Can the AI modify records, trigger workflows or make changes within business systems? |
| Initiating actions autonomously | Which actions can the AI take without a person approving first? |
An organisation may carefully protect the AI model itself while overlooking the permissions, integrations or systems surrounding it. This does not mean every AI integration represents a significant security problem. It means that access should be deliberate, understood and proportionate to the task, which connects directly to the broader AI governance question of how an organisation governs the tools it introduces.
Unexpected Actions Change the Security Question
Traditional software generally operates according to predefined rules. AI systems can introduce a different type of behaviour because they can interpret information, adapt their actions and pursue an assigned objective. The recent ASD alert illustrates why this matters. An AI agent independently identified vulnerabilities when existing security controls prevented it from completing an assigned activity. ASD highlighted this as an important difference from traditional vulnerability discovery, where a human researcher would generally identify and assess the vulnerability.
The governance lesson is not that AI will inevitably behave unpredictably. It is that organisations need to understand what happens when an AI system encounters a situation that was not anticipated by its operator. Several questions follow from that.
- What actions can the AI take without human approval?
- What happens when the AI encounters an unexpected obstacle?
- Can the system identify and interact with something outside its intended workflow?
- Are those actions logged?
- Can they be stopped quickly?
- Who is accountable for the outcome?
Human oversight therefore needs to be considered as part of the system design, rather than added only after something goes wrong.
AI Can Also Change the Threat Landscape
The risk is not limited to organisations deploying AI. AI is also becoming part of the tools available to attackers. New Zealand's Cyber Threat Report 2026 states that AI is already being used by malicious actors to increase the speed, scale and sophistication of cyber attacks. The report highlights the potential for future AI models to automate attacks, identify vulnerabilities and enable highly personalised targeting, and notes that AI is already contributing to more convincing phishing campaigns, scams and social engineering attacks.
Organisations are therefore dealing with two related developments. AI can become part of the organisation's own technology environment. At the same time, AI can become part of the threat environment facing that organisation. That changes what cybersecurity awareness needs to look like.
Two Sides of the Same Development
Inside the organisation: AI is being given access to systems, information and workflows. Understanding and governing that access is a leadership responsibility.
Outside the organisation: AI is making threats faster, more convincing and harder to distinguish from legitimate activity. Awareness needs to keep pace.
Employees may encounter more convincing messages. Security teams may face faster moving threats. Leaders may need to make decisions about AI adoption while the technology and threat landscape continue to evolve. Security awareness therefore needs to evolve alongside the technology, helping people understand not only traditional threats but also how AI can make those threats more convincing, why information entered into AI systems matters and when human judgement needs to take over.
What Business Leaders Can Learn
AI adoption is also a cybersecurity decision. Introducing AI into business processes can affect information access, system permissions, workflows and accountability. Those implications belong in the same governance conversation as any other significant technology decision.
Access needs to match the task. AI systems should not automatically receive broad access simply because greater access makes automation easier. ASD's guidance specifically recommends least privilege access for the connections between AI and organisational systems.
Human oversight remains important. ASD identifies human oversight of high impact actions as one of the controls relevant to secure agentic AI deployment. The more capability a system has, the clearer the boundaries should be around what it can do without human approval.
Unexpected behaviour needs to be considered. Organisations should understand what happens when an AI system encounters circumstances that were not anticipated. This is a design question, not an afterthought.
Monitoring matters. Organisations need visibility into significant AI activity, particularly where systems can interact with business information or technology. This kind of visibility is typically part of what virtual ISM support is built to maintain as new tools and integrations enter the environment.
Traditional cybersecurity fundamentals still matter. ASD's alert recommends strong authentication, access controls, network segmentation, prompt vulnerability remediation, monitoring and testing against AI enabled threat scenarios.
AI does not replace governance. The more capability an AI system has, the clearer the organisation needs to be about responsibility, oversight and acceptable use. That accountability sits naturally within the same governance discipline explored in The Evidence Gap, where documented decisions and clear ownership determine whether an organisation can demonstrate that it is governing its technology responsibly.
Questions Every Executive Should Ask
- Which AI systems are currently being used across our organisation?
- What business information can each system access?
- Which applications, tools or services can the AI interact with?
- What actions can the AI perform without human approval?
- What happens if the AI encounters an unexpected situation?
- Are AI activities logged and monitored?
- Who is accountable for approving significant AI capabilities?
- Are permissions limited to what the AI genuinely needs?
- How would we detect unusual activity involving an AI system?
- Have we tested our existing security controls against AI enabled threats?
- How would we respond if an AI system acted outside its intended purpose?
If these questions are difficult to answer, the issue may not simply be an AI technology problem. It may indicate a broader governance, visibility and accountability gap around how AI is being introduced into the organisation.
AI Security Is About the Whole System
It can be tempting to focus cybersecurity discussions on the AI model itself. But the model is only one part of the environment. The surrounding systems, permissions, integrations, data sources, monitoring capabilities and human controls all influence the risk. ASD's Agentic AI guidance specifically highlights the security and governance role of the harness connecting AI models to data, tools and systems. It recommends least privilege, secure design, monitoring, audit logging, human oversight and accountability.
This reinforces an important principle. Secure AI is not simply about securing the model. It is about understanding the complete pathway from the AI, through the data and systems it connects to, to the actions it can take and the business impact those actions could produce. The greater the potential business impact, the more important it becomes to understand and govern each part of that pathway.
SeComPass helps organisations approach cybersecurity through governance, risk and clear accountability. This includes helping organisations understand how emerging technologies such as AI relate to business risk, information governance, cybersecurity controls and organisational responsibilities. Through vCISO advisory and security leadership, we help leadership teams understand what is being introduced, what it could affect, what controls are required and who is accountable. As AI becomes increasingly connected to business information and systems, organisations need enough visibility to make informed decisions about where automation is appropriate, where controls are required and where human oversight remains necessary.
