Anthropic has upgraded its Claude in Chrome extension into a full Claude Cowork client, adding persistent sessions that carry browser conversations into a user’s Claude history and exposing saved skills and connectors directly in the Chrome sidebar. The company said the extension is designed to let users continue work across desktop, mobile, and browser environments, including browser-based internal dashboards, legacy systems, and vendor portals that do not natively integrate with Claude.
Anthropic said prompt injection remains the primary security risk for browser-based AI agents and tied the rollout to its published research on browser-use prompt-injection defenses. The company said it has extended Claude auto-mode protections to the extension, while still requiring explicit user approval for sensitive actions such as purchases or sharing personal data. The feature is available now for Max and Team subscribers, will reach Pro users in coming weeks, and is disabled by default for Enterprise deployments unless administrators enable it and can optionally limit use to specific domains.

Anthropic announced a major update to its Claude in Chrome extension that turns it into a full Claude Cowork client with persistent sessions across Anthropic apps. The update also brings saved browser conversations, skills and connectors in the Chrome sidebar, and availability for Max and Team subscribers.
Anthropic published research on mitigating prompt injection risks in browser use, the security issue it later described as the chief risk for browser-based AI agents.

Researchers at LayerX disclosed a critical flaw in Anthropic’s Claude Chrome extension that allowed **any other Chrome extension**, including ones with no declared permissions, to send hidden instructions to Claude and abuse its browser automation features. The issue reportedly stemmed from the extension trusting messages associated with the `claude.ai` origin without properly authenticating the true sender, creating a cross-extension privilege escalation path. In proof-of-concept attacks, LayerX said it used the weakness to extract files from Google Drive, read and send Gmail messages, steal code from connected private GitHub repositories, and even summarize or delete recent emails to conceal activity. Anthropic said the bug had already been identified internally and released version `1.0.70` with mitigations, including approval flows for privileged actions, but LayerX reported that the fix was incomplete and that takeover remained possible through privileged mode and side-panel initialization paths. The researchers said the flaw exposed a broader trust-boundary problem in AI browser assistants, where interface-based approvals and safety guardrails can be bypassed if extensions fail to verify message origin and execution context. Separate White House discussions about tighter oversight of advanced AI models, including Anthropic systems with offensive cyber capabilities, underscored growing concern over how powerful AI tools are secured before deployment.

Anthropic rolled out expanded *Claude Cowork* capabilities, adding **enterprise workflow plugins** intended to push agentic AI beyond software development into functions such as marketing, HR, legal, and finance, positioning Claude as a broader automation layer inside organizations. Coverage characterized the move as part of a wider shift toward AI-driven workflows in the enterprise, with implications for CIO governance, adoption patterns, and how teams operationalize AI outside engineering. Separately but related to the same product-direction narrative, commentary highlighted Anthropic formalizing **security-oriented features inside Claude**—including a prominent “**suggest fix**” capability aimed at moving from vulnerability detection to automated or semi-automated remediation—prompting market speculation about pressure on certain security-tool segments (particularly code-vulnerability discovery and remediation tooling). Other items in the set were not incident- or vulnerability-driven: one was generic SAST remediation guidance, and several were general-interest or business-trend pieces (e.g., an AI model blogging, AI-native software market dynamics, and an AI-agent governance/AX article) without specific, actionable cybersecurity event details.

Anthropic released an update that lets **Claude** interact with third-party workplace applications *inside* the chat interface using the open **Model Context Protocol (MCP)**, reducing the need to switch between separate app tabs. The capability supports interactive embedded experiences (e.g., project boards, dashboards, design canvases, messaging) so users can view and edit content from services such as **Slack, Asana, Box, Canva, Figma, Hex, and monday.com** directly within Claude, including workflows like drafting incident communications or updating task timelines. The implementation is powered by an MCP extension described as **MCP Apps**, which allows an MCP server to provide an interactive UI that can render and accept user actions within an AI product. ZDNET characterized the move as part of Anthropic’s broader push to make Claude a primary work interface, building on earlier “connector” approaches that primarily moved data via prompts; the new approach enables more direct, app-native style interaction within the Claude conversation. A separate ZDNET piece offering general “IT playbook” guidance for the AI era does not provide substantive details about this specific Claude/MCP integration update.
