Security & Threat Intelligence

One intrusion, two cyberattackers: Uncovering parallel threat activity
A good reminder that compromises are no longer single-actor events. This research shows how multiple threat actors can exploit the same breach simultaneously, reinforcing the need for layered visibility and rapid response.

Copilot — Cowork general availability

Copilot Cowork is now generally available

Copilot Cowork has moved out of preview and is now generally available. It lets users build agents and skills that automate repetitive, multi-step work across Microsoft 365 — drafting content, producing reports, triaging tickets and more — bringing autonomous task handling to everyday users.

Security — AI agent threats

AutoJack: How a single page can RCE the host running your AI agent

Microsoft’s Security team breaks down “AutoJack,” a technique where a single malicious web page can achieve remote code execution on the machine hosting an AI agent. It’s a clear illustration of the new attack surface that autonomous agents create when they browse and act on untrusted web content.

Security — Email protection

Microsoft Defender email security benchmarking: Key insights from one year of data

Drawing on a full year of benchmarking data, Microsoft shares what it’s learned about email threats and how organisations’ protection stacks up over time. Useful context for anyone tuning their Defender email-security posture.

Security — Industry recognition

Events — Microsoft Build 2026

Build 2026: Furthering Windows as the trusted platform for development(opens in new window) At Build 2026, Microsoft laid out a wave of developer-focused Windows updates aimed at reducing setup friction and making Windows the place to build and run AI agents. Highlights include Coreutils for Windows, WSL containers, one-command Windows Developer Configurations, and a new security layer called Microsoft Execution Containers (MXC) that lets developers tightly control what an AI agent can access. It matters because it signals Microsoft’s push to fold secure, on-device AI agents directly into the Windows developer experience.

Announcements — New Products

Introducing Microsoft Scout: Your always-on personal agent(opens in new window) Microsoft unveiled Scout, an “always-on” personal agent that works in the background across your Microsoft 365 apps, holding your priorities and acting on your behalf rather than just answering one-off questions. Scout is part of a new category Microsoft calls “Autopilots” — agents that run autonomously with their own identity, within the permissions you and your organisation set. (Shared as a video; full write-up is on the Microsoft 365 Blog(opens in new window).)

Industry News — Security

The next frontier in endpoint security: Securing local AI agents with Microsoft Defender(opens in new window) Tied to Build 2026, Microsoft extended its Agent 365 and Defender protections to cover AI agents running locally on a device, not just cloud-based ones. The idea is to give security and IT teams the same visibility, governance, and threat protection over local agents that they already have over human users, helping prevent these autonomous agents from becoming a new enterprise risk.

Introducing Microsoft 365 Business with Copilot: The new standard for small business(opens in new window) Microsoft is launching two new small-business SKUs on 1 July — Business Standard with Copilot and Business Premium with Copilot — with Copilot built directly into Word, Excel, PowerPoint and Outlook. They add 1,000+ connectors (Shopify, Xero, Docusign and more), “Work IQ” business context, and access to OpenAI and Anthropic models. Built-in security controls like sensitivity labels and access revocation ensure Copilot only surfaces what each user is permitted to see.
Introducing a new design for Microsoft 365 Copilot(opens in new window) Microsoft has redesigned the Copilot experience across Microsoft 365, turning the prompt line into a task-aware workspace with a single consistent entry point across apps and a progressive-disclosure interface. Performance improved with load times cut by more than half and complex prompts answering ~10% faster, alongside new agentic modes (Designer, Researcher, and in-app Word/Excel/PowerPoint agents). Microsoft reported usage gains of Word +27%, Excel +33%, PowerPoint +43% and Outlook +30%.

Security / Industry News

The Gentlemen ransomware: Dissecting a self-propagating Go encryptor(opens in new window) Microsoft Threat Intelligence analysed “The Gentlemen,” a ransomware-as-a-service threat (operators tracked as Storm-2697) written in Go that uses per-file Curve25519 + XChaCha20 encryption and spreads aggressively through lateral movement. It employs double extortion, disables Microsoft Defender, and deletes shadow copies and logs to hinder recovery. Activity has been observed globally across education, transport, healthcare and finance sectors.

Security & Threat Intelligence

Configuration becomes vulnerability: Exploitable misconfigurations in AI apps (14 May) Microsoft Defender researchers found that AI and agentic apps deployed on Kubernetes (Mage AI, kagent, AutoGen Studio, MCP servers, and others) are frequently exposed to the internet with weak or missing authentication, enabling remote code execution, credential theft, and data exposure without any zero-day exploit. Defender for Cloud signals show >50% of cloud-native workload exploitations stem from these misconfigurations. https://www.microsoft.com/en-us/security/blog/2026/05/14/configuration-becomes-vulnerability-exploitable-misconfigurations-ai-apps/(opens in new window)

Here’s a summary of the 10 stories posted in the Patrons News channel over the last 7 days, grouped by topic.

Security & Threat Intelligence

SOHO router compromise leads to DNS hijacking and AiTM attacks — Microsoft Threat Intelligence reports that Russian military-linked actor Forest Blizzard (sub-group Storm-2754) has compromised insecure home/small-office routers, redirecting DNS to attacker-controlled infrastructure to enable adversary-in-the-middle attacks against Outlook on the web. Over 200 organisations and 5,000 consumer devices have been impacted since August 2025. https://www.microsoft.com/en-us/security/blog/2026/04/07/soho-router-compromise-leads-to-dns-hijacking-and-adversary-in-the-middle-attacks/
ClickFix campaign uses fake macOS utilities to deliver infostealers — Threat actors are posting fake macOS troubleshooting guides on Medium, Squarespace and Craft pages instructing users to paste Terminal commands that install Macsync, Shub Stealer or AMOS infostealers, which exfiltrate Keychain entries, iCloud data and crypto wallet keys (and sometimes replace Ledger, Trezor and Exodus apps with trojanised versions). https://www.microsoft.com/en-us/security/blog/2026/05/06/clickfix-campaign-uses-fake-macos-utilities-lures-deliver-infostealers/
Multi-stage ‘code of conduct’ phishing leads to AiTM token compromise — A large credential-theft campaign (April 14–16) targeted ~35,000 users across 13,000 organisations in 26 countries, mostly US, using polished “internal regulatory” emails with PDF attachments. The chain ran through CAPTCHAs and staging pages before hitting an AiTM Microsoft sign-in flow that captures auth tokens. https://www.microsoft.com/en-us/security/blog/2026/05/04/breaking-the-code-multi-stage-code-of-conduct-phishing-campaign-leads-to-aitm-token-compromise/
