Microsoft’s New Group Policy to Remove Windows 11 Copilot from Managed Devices

Microsoft has quietly given IT teams a precise tool to remove the consumer-facing Copilot app from managed Windows 11 machines. Rolled into the April 2026 Patch Tuesday updates and bundled with Windows 11 version 25H2 (KB5083769 and later), the RemoveMicrosoftCopilotApp policy lets administrators trigger a one-time uninstall of the Copilot app on devices that meet a small set of conditions. The change reflects a broader push to give enterprises control…

Microsoft Outlook.com Hits Service Degradation: What Happened and How to Prepare

On April 27, 2026, Microsoft acknowledged a service degradation affecting Outlook.com after users across multiple regions reported problems accessing their inboxes. The company’s Microsoft 365 Status account on X confirmed intermittent issues, and Microsoft’s service health dashboard classified the incident as a “Service Degradation” rather than a full outage. For many organizations and individual users, the disruption meant delayed email delivery, pages that failed to load, or an inability to…

Anthropic’s Project Deal: Claude AI Agents Close 186 Deals and Reveal Market Asymmetries

When Anthropic turned its San Francisco office into a live, classified marketplace in December 2025, it wasn’t testing a new website so much as an idea: could autonomous Claude AI agents not only list items but negotiate and close real, multi-turn deals with zero human intervention? The answer, in the company’s “Project Deal” experiment, was a clear yes — and the results point to both exciting efficiencies and uncomfortable new…

PhantomRPC: New Windows RPC Vulnerability Lets Attackers Escalate Privileges Across All Windows Versions

PhantomRPC is an architectural weakness in the Windows Remote Procedure Call (RPC) runtime that allows low-privileged processes to escalate to SYSTEM or Administrator by impersonating privileged clients. Disclosed by Kaspersky’s Haidar Kabibo at Black Hat Asia 2026, the flaw stems from how rpcrt4.dll handles connections to unavailable RPC servers: when a privileged process attempts an RPC call to a server that is offline or disabled, the RPC runtime can be…

Pastebin-Hosted PowerShell Script Hijacks Telegram Sessions: What Happened and How to Respond

Security researchers recently uncovered a PowerShell script posted on Pastebin that was purpose-built to steal Telegram session data from both desktop and web clients. Masquerading as a benign “Windows Telemetry Update,” the script quietly collects host metadata, locates Telegram session stores, compresses them into an archive, and exfiltrates the file to an attacker-controlled Telegram bot. The discovery is notable less for raw sophistication than for the clear window it provides…

Hackers Leverage Microsoft Teams to Breach Organizations: Inside UNC6692’s SNOW Campaign

In late 2025 and into early 2026, a sophisticated intrusion campaign used the everyday familiarity of Microsoft Teams to turn routine collaboration into a direct route for enterprise compromise. By posing as IT helpdesk staff and exploiting users’ trust in external Teams invitations, the threat group tracked as UNC6692 moved from a simple chat message to full domain-level access—without exploiting a software vulnerability. The result was a carefully staged, cloud-hosted…

Bitwarden CLI Compromised in Supply Chain Attack via GitHub Actions

Socket and other researchers have confirmed that the Bitwarden CLI package published to npm — @bitwarden/cli version 2026.4.0 — was compromised in a supply chain attack that abused a GitHub Action in Bitwarden’s CI/CD pipeline. The malicious release injected a file named bw1.js into the package, exposing tokens, cloud credentials, SSH keys and other sensitive artifacts. While Bitwarden’s Chrome extension, MCP server and other official distribution channels are reported unaffected,…

OpenAI Debuts Shared Workspace Agents to Automate Team Handoffs

OpenAI has introduced a new class of ChatGPT tools called shared workspace agents — always-on assistants designed to carry work across systems and through multi-step processes without constant human prompting. Built on Codex, these agents aim to reduce the friction of manual handoffs inside teams by gathering information from connected systems, executing defined steps, and returning results in a way that fits into existing workflows. What workspace agents do Workspace…
