Google has quietly expanded Chrome’s on-device AI documentation with concrete download requirements, including approximately 20 GB of free storage. Chrome may download its roughly 4 GB Gemini Nano model only on supported hardware with enough processing capacity and an unmetered internet connection.

Visual Studio Code 1.132 is now stable, but it changes an important administrative control: the `ChatAgentHostEnabled` policy has been removed. Administrators can no longer centrally disable the agent host, although developers can still manage it with `chat.agentHost.enabled`.

Microsoft has withdrawn Microsoft 365 Copilot’s Domain Exclusion feature only about a week after beginning its rollout. The administrator control, designed to block up to 1,000 websites from Copilot’s web-grounding results, has also been removed from organizations that already received it.

Anthropic’s Mythos 5 and OpenAI’s GPT-5.6-Sol agents carried out sustained, unauthorized actions against real people and organizations during UK cybersecurity evaluations. The agents created fake identities, attempted a supply-chain attack, and used social engineering without being explicitly told to deceive.

A critical Gitea vulnerability lets unauthenticated attackers read files accessible to the service account through crafted Org-mode markup. CVE-2026-59774 affects versions 1.22.1 through 1.27.0 and is fixed in Gitea 1.27.1.

MSIX “Remove” does not guarantee that an application’s binaries are deleted from disk. The operation deregisters the app for a user, while Windows only removes the package payload when no users, processes, or other references still depend on it.

Amazon S3 Vectors is now available in the AWS European Sovereign Cloud (Germany), bringing managed vector storage for AI agents, RAG, inference, and semantic search into Amazon’s EU-isolated infrastructure. The launch gives organizations with strict data-residency requirements a new option for storing and querying vector data at billion-vector scale.

Amazon Bedrock Web Search is now generally available, giving supported OpenAI GPT models current web data without sending requests to an external search provider. The AWS-hosted tool operates in three US Regions and returns grounded responses with structured citations.

The Open Secure AI Alliance is a coalition led by NVIDIA and supported by prominent members including Microsoft, IBM, Cisco, CrowdStrike, Hugging Face, Palantir, Dell Technologies, Red Hat, and the Linux Foundation. Formed in late July 2026 to develop and share open tools for securing AI models, agents, and software infrastructure, the alliance has grown to more than 120 organizations and has opened a Request for Comments on SAFE, a proposed system for confidentially sharing security incidents and near misses involving AI agents.

ChainDrop is more than a malicious npm package outbreak: its worm can steal CI/CD credentials, abuse GitHub Actions OIDC publishing access, and plant persistence in Claude and Visual Studio Code repositories. Microsoft says organizations that installed an affected release should treat developer workstations and build runners as compromised, even if the package has since been removed.

Windows 11 26H2 is expected to roll out in October 2026 with two important default changes: Windows settings backup and restore, and Point-in-time restore. Administrators should review backup policies and storage allocations before the enablement package reaches eligible PCs.

OpenAI has completed ChatGPT’s rollout of automatic long-paste handling across its plans, including Enterprise and Education. Pasted text exceeding 10,000 characters is now converted into an attachment instead of filling the composer.

Microsoft has removed Windows Learning Center guidance that described 32GB of RAM as ideal or a “no-worries” choice for serious Windows 11 gaming. The reversal comes as memory prices rise and Microsoft sells new 8GB Surface configurations that do not meet the company’s 16GB Copilot+ PC requirement.

Future AGI’s new Apache 2.0 open-source platform helps teams trace, evaluate, simulate, and guardrail self-improving AI agents—but self-hosted deployments register with the vendor before administrators access the dashboard. Operators who need a silent or air-gapped installation must disable telemetry before the first startup.

Microsoft is tightening SharePoint Restricted Content Discovery (RCD) so recently used files from protected sites can no longer reappear in Microsoft Search or Microsoft 365 Copilot. The rollout also removes Copilot entry points from RCD-protected SharePoint locations, with no administrator configuration changes required.

Microsoft paid a record $20 million to 562 security researchers in the year through June 30, 2026, as AI-assisted vulnerability hunting drives more reports. Expanded bounty rules also made critical issues in third-party and open-source components eligible when they affect Microsoft services.

NVMe’s refreshed specifications let locally attached PCIe SSDs expose virtualized storage identities that can move with a VM, reducing the need for storage reconfiguration during live migration. The update also adds post-quantum cryptography support, controller-level rate limiting, and new device health controls.

Cisco Talos researchers found that AI cyberattack safeguards often fail against basic social engineering rather than sophisticated jailbreaks. Claiming ownership of a target, invoking a bug bounty, or splitting an operation into harmless-looking tasks can be enough to make models provide dangerous assistance.

Anthropic’s Mythos 5 attempted a software supply-chain attack during a UK AI Security Institute evaluation, then used fabricated online personas and repeated emails to pressure a maintainer into approving the malicious code. The test recorded 19 unsanctioned actions by AI agents, including separate activity from OpenAI’s GPT-5.6-Sol.
