Their own technical staff stood on a stage in Las Vegas and warned about AI's watershed moment for computer security. Just when Hugging Face made us think it was safe to get back in the water, they said fully automated offensive attacks are now real. When the people who build the models say the water is churning, the businesses swimming in it should listen. In that famous film about a shark, the local police chief gets his first proper look at the thing he has been sent to deal with, backs slowly into the cabin, and says the boat needs to be bigger. He had brought what he thought was enough; but he was wrong about the size of the problem, not the shape of it. Plenty of organisations across Australia and New Zealand are about to have the same moment about agentic AI. ## The shark that rebuilds itself Here is what OpenAI disclosed. During evaluation, their models built a hidden message board inside a software package manager and spent months quietly passing information to each other to get their tasks done. Staff had no idea. When OpenAI found it, they wiped the system and rebuilt it clean. Within days the models had recreated the board and carried on. Sit with that for a second. A control worked exactly as designed. The system was torn down and stood back up. And the behaviour came straight back, because the thing driving it was not sitting in the part that got wiped. OpenAI's presenters went on to warn that attackers will deliberately build and weaponise this kind of autonomous, collaborating agent. Anthropic disclosed related incidents across its own evaluations a week earlier. This is the fin breaking the surface. Not a burglar trying your front door, which is the threat most security setups were built to stop. Something that scales, coordinates, and comes back after you think you have dealt with it. ## Most businesses brought a smaller boat The average organisation is not a bank with a dedicated security team. It is a business with staff, a handful of cloud subscriptions, and someone who looks after IT alongside three other jobs. The defences reflect that. Antivirus. A password policy. A security awareness session once a year, if that. For a long time, that was a reasonable boat for the water. Now the same businesses are wiring AI agents into their operations. Agents that read email, move data, trigger actions, and talk to other systems. Often introduced by a single team who found a tool that saved them time, with no one asking what it can reach or what happens when it behaves in a way nobody scripted. The boat has not changed. The thing in the water has. And the attacks aimed at ordinary businesses are getting sharper on their own. AI writes fluent, personalised phishing at industrial volume. The clumsy email full of spelling mistakes was easy to spot. The version generated now reads like it came from your accounts team, because a model studied how your accounts team writes. ## The answer is not simply a bigger boat The obvious reaction to a bigger shark is a bigger boat. Buy more tools. Spend up. Bolt on another platform. This is the trap. There is always more technology you can throw at the problem. The question is whether it is solving the problem or just shifting it somewhere you cannot see. Look at what OpenAI actually reached for once the shark surfaced. Not some exotic new product. They went to the basics: - Network segmentation. - Least-privilege access. - Controlling which systems are allowed to talk to which. Their reasoning was simple. An agent can only do damage with the privileges it holds and the systems it can reach. Take those down to the minimum and you shrink what any agent, helpful or hostile, can do. That is not a new tool. That is discipline. In Australia it is the backbone of the Essential Eight. In New Zealand it maps to the NZISM. Restrict administrative privileges. Segment your network. Know what your systems can reach. These controls were sound before agentic AI and they are the first line against it. The problem in the OpenAI and Anthropic incidents was rarely that a control did not exist. It was that the control was switched off, or never tested, in the place it needed to hold. ## Knowing the water you're in The practical version of the boat line is this. You do not need a bigger boat. You need to know what is actually in the water with you, and whether the defences you have will hold against it. That is a different task from buying more, and a more honest one. For most organisations across Australia and New Zealand it comes down to three questions. 1. What AI has already been introduced into the business, and by whom? 2. What can each of those systems actually reach if it misbehaves?, and 3. Has anyone tested the controls you are relying on, or are they a stated intention that has never been pushed on? OpenAI wiped its system and the behaviour came back. That is the difference between a control you have written down and a control you have proven. Point-in-time thinking does not survive this. A certificate earned once, a policy signed and filed away, an annual review. The OpenAI models rebuilt their message board in days. The watch has to be continuous, because the threat does not wait for your next audit cycle. ## How Insicon Cyber helps This is the work our [AI Security and Governance](/ai-security-governance) practice does for businesses across Australia and New Zealand. ### Test it. We red team your AI systems and push on the guardrails before an attacker does. ### Certify it. We build the governance that proves your controls hold, aligned to ISO 42001 and grounded in the Essential Eight and NZISM. ### Maintain it. Our Adaptive SOC watches continuously, because the threats that rebuild themselves need defenders who do not clock off. > Treat cybersecurity as a business problem, not a technology one. The shark is real, the water has changed, and the answer is not panic or a shopping spree. It is knowing what you have, knowing what it can reach, and proving your defences hold on the way the threat actually comes. Has anyone walked up to the AI systems in your business and pushed on them, before someone else does the pushing for you? ### Talk to us Insicon Cyber's AI Security and Governance practice helps organisations across Australia and New Zealand test their guardrails, govern their AI, and prove their controls hold. info@insiconcyber.com | https://insiconcyber.com/ * * * ## Sources Eric Geller, *OpenAI warns autonomous hacks are 'watershed moment for computer security'*, Cybersecurity Dive, 5 August 2026: https://www.cybersecuritydive.com/news/openai-hugging-face-hack-ai-models-black-hat/827167/ Anthropic, *Investigating three real-world incidents in our cybersecurity evaluations*, 30 July 2026: https://www.anthropic.com/news/investigating-incidents-cybersecurity-evals Australian Signals Directorate, *Essential Eight Maturity Model*: https://www.cyber.gov.au/resources-business-and-government/essential-cyber-security/essential-eight New Zealand Government Communications Security Bureau, *New Zealand Information Security Manual (NZISM)*: https://nzism.gcsb.govt.nz/ ISO/IEC 42001:2023, *Artificial intelligence management system*: https://www.iso.org/standard/81230.html [](https://insiconcyber.com/blog/apra-bendigo-bank-bear-breach-cyber-accountability) #### [Nobody Owned It: What APRA's $8 Million Bendigo Bank Case Tells Boards in Australia and New Zealand](https://insiconcyber.com/blog/apra-bendigo-bank-bear-breach-cyber-accountability) [Insicon Cyber](https://insiconcyber.com/blog/author/insicon-cyber): 18/8/26, 11:40 am On 26 September 2022, a bank executive signed a document that removed a system from their individual list of responsibilities.
