Securing Microsoft 365 against rogue AI agents and identity threats

Organizations are increasingly facing risks from rogue AI agents that bypass traditional security perimeters by masquerading as legitimate user identities. These autonomous systems can gain persistent background access through unmanaged user consent or by exploiting legacy authentication flows like device-code and Resource Owner Password Credentials. Because these agents often borrow first-party application IDs, they leave no distinct service principal footprint in Microsoft Entra, making them difficult to distinguish from standard user activity.

📰 Ubuntu’s ‘Myna’ AI lets you talk instead of type – but how does it work

As you will know, Ubuntu is adding AI features this year, and Ubuntu founder Mark Shuttleworth hopes the distro will become the OS for the ‘agentic’ era. But big ambitions begin with a small seed, and the first is planted is a speech-to-text tool dubbed Myna. Name: Myna. Age: Minus 4 months (it’ll debut in Ubuntu 26.10, out in October). Appearance: A keyboard shortcut you press to avoid using your keyboard for typing.

📰 Fedora 45 Looks To Finally Offer Install Support For Stratis Storage

Ever since RHEL deprecated their short-lived Btrfs plans, Red Hat engineers over the past decade have been developing Stratis Storage as their storage management solution leveraging XFS, LUKS, DM, and their Rust-based daemon. While Stratis Storage has been available in Fedora Linux going all the way back to Fedora 28, until now there hasn't been the option of using it for the root file-system on new Fedora installations.

Open Memory Protocol enables cross-tool context sharing for AI agents

The Open Memory Protocol (OMP) has launched as a vendor-neutral specification designed to provide a unified memory store for disparate AI tools. This system allows developers to maintain context and user preferences when switching between different platforms like Claude and ChatGPT. By using a shared-memory architecture, compatible clients can read and write to a single user-controlled server instead of maintaining isolated data silos.

Gemini now generates fully editable multi-slide presentations in Google Slides

Google has updated Slides to allow the Gemini AI engine to generate complete, multi-slide presentations from a single text prompt. Unlike previous iterations that produced static templates, this update creates native layouts where every element, including text and images, remains fully editable by the user. The system includes a planning phase where the AI asks follow-up questions regarding the target audience and tone before generating a reviewable outline.
