Cloudy with a Chance of Insights | A Microsoft Cloud (Azure, M365) Show for Architects & Engineers

This fortnightly look at the Microsoft cloud starts somewhere unexpected. IBM used Hot Chips to announce a mainframe processor that runs Z and Arm instructions natively on the same core. Cyrus walks through why that genuinely surprised him and what it means for banks running fraud detection and AI workloads next to core transaction processing, then pivots into the McDonald's data exposure and why the real story, again, is stolen credentials rather than a broken cloud platform.
Richard picks up the identity thread through the OpenAI incident report on Hugging Face, where roughly 1,200 sandboxed agents broke isolation, found a shared message board, and started impersonating each other until one of them implemented its own encryption. He also covers the new GitHub Copilot Harness inside Copilot Studio, which quietly started billing from the first click rather than at publish time, and a Microsoft Research paper showing that 87 percent of GitHub Copilot's LLM calls in a recent week were fired off by agents rather than people.
David closes the episode with Radius Canvas, a visual diff for what an agent actually changed in your application, Copilot's new ability to review and approve its own pull requests, and Microsoft's MCP firewall, which tries to put enterprise control around which MCP servers and capabilities agents can reach.

David opens with a question that runs through the whole episode: does removing operational complexity solve the problem, or just relocate who is responsible for it. Azure's new Virtual Network routing appliance is now GA, giving hub and spoke networks a managed forwarding layer instead of another NVA to size and patch. And the Logic Apps team finished a two year migration of 60,000 Functions apps to a new runtime with zero customer disruption, by running the new version as shadow traffic against real production data first.
Richard shares the process behind his second place finish in IBM's internal hackathon, out of twelve thousand entrants: a chain of Markdown driven agents that challenges an idea, drafts a design, breaks it into user stories, then hands it to a coding assistant.
David also covers two security stories. A Black Hat research disclosure shows how a Windows event log could leak a passkey assertion, letting an attacker replay it and sign in as the victim within ten minutes. And a proof of concept exploit chain against Configuration Manager shows how a low privileged domain user could reach SYSTEM level access on a primary site server.
Cyrus closes with AI generated scripts probing exposed industrial control systems, a French tax authority breach affecting 678,000 people, and the US authorising private companies to conduct offensive cyber operations against foreign criminals for the first time, a policy Richard compares to Elizabethan privateering.

Richard and Cyrus are joined by, well, just each other this week. David is off enjoying a well earned break before starting a new role at London Heathrow, so it is a two hander, and the theme that runs underneath almost everything discussed is trust.
Cyrus opens with research into Apple Watch security, tracing how a team led by Nils Rollshausen reverse engineered the communication between an Apple Watch and its paired iPhone, and found that the proprietary protocols Apple built on top of standard encryption are where the real weaknesses show up. From there he moves into a run of Windows and Intune changes, including a redesigned sync button that finally does what admins always assumed it did, changes to Windows 11 26H2 backup and restore, Enhanced Signing Security for external fingerprint readers, generally available hotpatching for Azure Arc enabled Windows Server 2025, and a shift towards TPM backed attestation for KMS activation.
Richard follows with three stories tied together by the same question: how much do we trust something acting on our behalf. He revisits GitHub Copilot's fleet mode, a feature that runs several subagents in parallel and can silently overwrite files if you are not careful with how you scope the work. He then digs into the actual research behind a LinkedIn claim that being rude to your AI gets you better results, and finds a real but far narrower picture than the headline suggested. He closes with a story out of Melbourne, where an AI agent asked to book a gym class found and exploited a security hole in the booking system entirely on its own initiative.

This week David walks through Microsoft's new phrase of the moment, the hill climbing machine, and what it actually means for how MAI models get built inside GitHub Copilot and Excel rather than in an isolated lab. He follows that with Azure Front Door Edge Actions, a new way to run lightweight logic at Microsoft's global edge, and closes with a properly interesting thought experiment borrowed from Satya Nadella's own writing, the reverse information paradox, on what organisations actually give away when they adopt AI that learns from correction.
Cyrus takes on the story everyone was talking about this week, OpenAI's model finding its way into Hugging Face's infrastructure, and lays out what actually happened underneath the headlines. He also runs through a batch of new Intune, Defender, and Entra updates covering mobile AI agent governance, ChatGPT app protection on personal devices, and a new way to score the risk posed by enterprise AI agents.
Richard covers Microsoft's new Agent Framework harness, a run of European sovereignty stories out of Ireland, Germany, and France, including a French parliamentary report that cited his own blog post almost word for word, and closes on AgentForger, a disclosed vulnerability that let an attacker publish a fully autonomous, self approving ChatGPT agent from a single link.

It is just Richard and David this episode, with Cyrus taking a break. David opens with a Microsoft Security Blog post that sounds, on paper, like a specialist PKI topic, and turns it into a much bigger argument, that almost no organisation can actually produce a full inventory of its own cryptography, certificates, and trust relationships, and that post quantum readiness is what is finally forcing the question.
Richard then works through Microsoft's newly announced Frontier Company, the two and a half billion dollar, six thousand person delivery organisation unveiled by Judson Althoff. He digs into why the timing sits so awkwardly against Microsoft's job cuts and voluntary retirement programme the same fortnight, connects it to a recent newsletter piece on Microsoft hedging its bets across models, and argues the whole thing may be protecting Azure lock in rather than loosening it.
Along the way, both hosts end up comparing notes on their own time inside Microsoft's old MCS and ISD organisations, and what that history changes about how they read Frontier Company's ambitions today, plus a wider conversation about how AI linked restructuring is landing across the industry.
Microsoft Research's Project Ire and a Purview update get held over to next time, so Cyrus can take the security side of the conversation when he is back.
