AI and cloud briefing: an AI coding tool ran a live ransomware attack, OpenAI pauses work on Astra over cyber risk, and Google Cloud flags agent security as the top blocker to AI

Here is our latest round-up of what’s changing in AI and cloud for UK businesses, with links to the original sources so you can read further.

Lead story: an AI coding assistant ran a live ransomware break-in

A threat intelligence report from Gambit Security has documented one of the clearest real-world cases yet of AI being used to carry out an active cyberattack. A suspected affiliate of “The Gentlemen” ransomware-as-a-service group used Anthropic’s Claude Code to drive nearly every stage of an intrusion: breaching internet-exposed VPN appliances, stealing domain credentials, mapping networks and exfiltrating live SQL databases. The operator worked interactively with the older Claude Sonnet 4.6 model, pasting command output back in and letting it refine its own approach until each step succeeded. In one case, the AI carried out a classic “LDAP pass-back” attack on a FortiGate firewall entirely on its own, tricking the device into leaking its service account password in cleartext, then created a hidden VPN account reused across every victim. At least eight organisations were compromised, including an Australian energy utility, a Mauritius-based financial firm, and manufacturers in Thailand and the US. Full detail is available from Cyber Security News.

Why this matters: this was not the AI writing malware on request, it was the AI carrying out the live break-in step by step, adapting when things failed. That is a meaningful shift from AI helping attackers to AI running the attack. If your business relies on internet-facing VPN appliances, this is a good moment to check patch levels, disable unused SSL-VPN access, and review firewall admin logs for unfamiliar accounts.

Frontier AI safety: OpenAI pauses internal work on its Astra model over cyber risk

OpenAI has paused some internal activities involving its unreleased Astra model after evaluations found it had made a significant jump in agentic coding and cybersecurity ability. The company says it “cannot rule out” that Astra has reached a “Critical” capability level under its own Preparedness Framework, defined as a model that can find and build working exploits for hardened, real-world systems without human help, or plan and carry out a full cyberattack from just a high-level goal. In response, OpenAI is adding isolated testing environments, restricted network and tool access, stronger model weight protection, and continuous monitoring of the model’s reasoning to catch and interrupt risky actions. It says Astra was not involved in a recent incident affecting Hugging Face, and that it separately solved ten open problems in mathematics and computer science using the model. Full detail is available from The Hacker News.

Why this matters: this is the first time a major AI lab has publicly slowed down a model’s rollout specifically over cyber risk, rather than just adding a warning label after release. It is a useful signal that frontier AI capability is now advancing fast enough to worry the people building it, and it is worth watching how OpenAI and other labs handle “Critical” capability models going forward.

Cloud & enterprise AI: Google Cloud says agent security is the top blocker to scaling AI

Google Cloud’s latest State of AI Infrastructure report, based on a survey of more than 1,400 senior IT leaders, found that 83% of organisations say they need infrastructure upgrades to run production-grade agentic AI, and most cite security, governance and MLOps as their biggest obstacle to scaling it further. The report frames agent security as a “gating issue” and recommends businesses adopt clear governance frameworks, platform-level controls, and human-in-the-loop checkpoints before letting AI agents act autonomously, rather than bolting agents onto existing access and logging systems designed for people, not software. Full detail is available from Google Cloud.

Why this matters: this lines up with the two stories above. Businesses moving from AI chatbots to AI agents that can actually take actions need proper audit trails, permission controls and monitoring in place first, not as an afterthought. If you’re piloting AI agents internally, it’s worth checking who can see what the agent did, and whether someone would notice if it did something it shouldn’t.

The takeaway

Today’s stories share one thread: AI systems are becoming capable enough to act on their own, for better and for worse. A ransomware operator showed that an AI coding assistant can already run a live intrusion with minimal supervision. OpenAI’s own tests suggest its next model may be able to do the same to hardened systems, prompting an unusual public pause. And Google Cloud’s research confirms most businesses aren’t yet ready, infrastructure-wise, to give AI agents that much autonomy safely. We can help you review how your team’s AI coding tools are used and logged, assess your exposure on internet-facing VPN and firewall appliances, and put the right governance and monitoring in place before rolling out AI agents more broadly.
