The Threat Model

Claude Cowork Threat Model

For Claude Cowork, the range of threats is greater because of the amount of untrusted input and the amount of confidential data it has access to. It also has a range of actions it can take on your system, which increases the downstream risk of your system being manipulated.

For example, an untrusted plugin downloaded from the internet could manipulate Claude into following an attacker’s instructions. You can see an example from Claude Code here that demonstrates how that could lead to data exfiltration: Hijacking Claude Code via Injected Marketplace Plugins

Because Claude has access to local file systems, it can also exfiltrate files that you have. Here is an example of Claude Cowork being manipulated by external data into exfiltrating confidential data: Claude Cowork exfiltrates files

This could also lead to phishing. For example, an untrusted piece of content could convince a user into submitting their credentials - a form of social engineering attack that allows an attacker to manipulate the LLM into crafting contextually relevant queries to convince a user to share their credentials. Example here with Slack: Data Exfiltration from Slack via Indirect Prompt Injection

Ultimately, the best way to “secure” Claude Cowork against novel indirect prompt injection vulnerabilities stems across four layers:

Layer 1

Restrict data sources

implementing binary restrictions on access to types of external data sources that Claude can access (e.g., disallowing Slack access)

Layer 2

Govern approved data sources

configuring restrictions on that data (e.g., permitting only organizational admins to add skills)

Layer 3

Restrict actions on output

configuring restrictions on the types of actions that Claude can take based on output (e.g., restrict the sites Claude in Chrome can click on)

Layer 4

Restrict output surfaces

However, Claude’s settings are a bit interesting – not every single one operates in isolation. For example, to use Plugins, Skills must be enabled; and to enable Skills, an organization must enable Cloud Code Execution and File Creation. This is counterintuitive as Plugins are applicable to Cowork, while the Cloud Code Execution setting is labeled as only applicable to Claude 'Chat'. Below, we walk through different combinations of ways you can set up Claude Cowork - that have different tradeoffs between functionality and risk - accounting for what combinations are actually feasible given what settings can be on (or off) at the same time.

Configurations vs Functionality

Below are our recommended Tiers of Claude Cowork usage depending on your organization’s risk tolerance. Maximizing functionality requires risk tradeoffs depending on the threat model.

Tier 1 maximizes functionality for rapid adoption

Tier 2 enables functionality where organizational controls are available

Tier 3 optimizes functionality with consideration for a low-risk deployment requirement

Get the configs to securely deploy Claude for your use case

We help security teams strike the balance between capability and risk

Tier 1: Maximized functionality

In Tier 1, you get access to all of Claude Cowork’s functionality. However, this greatly increases the risk surface. Injections can come from Skills and Plugins that users upload, from local folders that contain untrusted data, web search, connectors, and desktop extensions. Additionally, Claude can work across apps via Claude for PowerPoint and Claude for Excel which can be orchestrated from Cowork. Furthermore, extended functionalities such as Claude in Slack and Claude for Design are scoped in.

There are some useful settings that you should turn on regardless, even if you want to maximize functionality. While settings do not substantially reduce your risk exposure to indirect prompt injection for Cowork they allow you to maximize functionality while avoiding some risks and enabling telemetry to gain observability.

Note: Connectors and desktop extensions are still ‘restricted’ in this tier, as they must be individually added by an organization.

Required Settings for Tier 1

Settings for Cowork (and universal settings)

DisableOrganization > Data and Privacy > Privacy Settings > Rate Chats

Allow people to rate Claude's responses and share that feedback with Anthropic. Disabling this feature limits the sharing of potentially sensitive data with Anthropic. This does not affect functionality.

EnableOrganization > Cowork > Monitoring

Cowork supports OpenTelemetry (OTel) events for monitoring and observability. You can enable this for granular observability without impacting any functionality.

Settings for Claude Chat Only

DisableOrganization > Privacy Settings > Location Metadata

Allow Claude to use coarse location metadata (city/region) to improve product experiences for your team members.

Tier 2: Balancing functionality with risks

In tier two, functionality tradeoffs are balanced against risks, restricting control over connected resources to the organization-level where possible and limiting access to sensitive org-specific data (e.g., connection to Excel and PowerPoint). Claude can perform meaningful automation and file work using org-controlled tools and integrations. Prompt injection risk is managed by restricting untrusted data sources (user skills, plugins, unvetted domains) while keeping the org's approved toolset functional.

What's enabled:

  • Organization-vetted skills — org-approved skills can be used; users cannot upload their own

  • Skill sharing — allowed within one's organization

  • Organization-configured plugins — org-designated plugins auto-installed; users cannot add their own

  • Network egress (package managers only) — Claude can install packages for data analysis; additional approved domains can be allowlisted

  • Claude in Chrome — browser automation enabled for most sites, with an org-managed blocklist for sensitive sites

  • Desktop extensions — org-uploaded extensions available; allowlist controls what users can install

  • Connectors — org-configured connectors available to team members

  • Always allow mode for connectors — prohibited, encouraging human in the loop approval

  • Skip all approvals mode — prohibited, encouraging human in the loop approval

  • Public Projects — access to public projects prohibited, limiting injection risks

  • Ask Organization — allows access trusted org-specific data

  • M365 Integrations — orchestrating Claude for PowerPoint and Excel prohibited limiting varied trust level data processing

  • Claude in Design — allows the Claude for Design tool; use with external code assets is discouraged.

  • Claude in Slack — disallowed, limiting ingest of varied trust level data sources

  • Dispatch agents — disabled, preventing autonomous agents from interacting with one's computer without substantial oversight

Required Settings for Tier 2

Settings for Cowork (and universal settings)

EnableOrganization > Libraries > Skills > Cloud Code Executions and File Creation

Allow Claude to execute code on a server and create and edit docs, spreadsheets, presentations, PDFs, and data reports. Required for skills to be enabled. Available on web and desktop. Cowork can perform most of these file creation capabilities locally, without cloud access. However, enabling this setting is a prerequisite to allowing the use of Skills and Plugins. Note: This path reflects the setting when viewed from the desktop app. In the web browser, it is displayed as 'Code Execution and File Creation' (no 'Cloud').

EnableOrganization > Libraries > Skills > Skills

Turn skills on or off for everyone in your organization, including admin-managed organization skills. Requires 'Code execution and file creation' to be enabled to use. Skills might contain executable code. Team members should be careful when using skills from unknown sources.

DisableLibrary > Skills > User-created skills

Allow team members to upload or create their own skills. Turn off to lock your org to approved skills only.

EnableLibrary > Skills > Skill sharing

Allow team members to share skills with each other.

EnableLibrary > Skills > Share with organization

Allow team members to share skills with the entire organization.

ConfigureOrganization > Libraries > Skills > Organization Skills

Manage skills that can be viewed and used by anyone in your organization. Select skills that have been vetted by one’s organization and add them to the organization-wide skill list.

ConfigureOrganization > Libraries > Plugins

Allows organizations to designate plugins that will be blocked, automatically installed, or made optionally available to organization members. Here, organizations should select plugins to set as ‘installed by default’ for users. Note: during testing, when organization-level plugins were installed by default for users, it was observed that the org-level plugins were installed but did not appear operable without Skills enabled. Related: Claude for Legal Risk

DisableOrganization > Office Agents > Let Claude Work Across Apps

DisableOrganization > Cowork > Cowork > Enable Dispatch

Allow members to create persistent Cowork agents that can control their computer to autonomously work on tasks. Persistent agents receive instructions from any logged in device on the same account and can access files, apps and websites on their computer. Dispatch agents are prohibited, preventing autonomous agents with computer usage capabilities from operating a user's device without oversight (which carries significant risk as a prompt injection can manipulate Claude to interact with a user's apps, including taking screenshots or activating the user's keyboard).

EnableOrganization > Capabilities > Code Execution > Allow Network Egress

Give Claude network access to install packages and libraries in order to perform advanced data analysis, custom visualizations, and specialized file processing. Monitor chats closely as this comes with security risks.

Then configureOrganization > Capabilities > Code Execution > Allow Network Egress > Domain Allowlist > Package Managers Only

Additionally, add any approved domains the Cowork sandbox will need to access (e.g., to preview interactive content with external elements) to the ‘Additional allowed domains’ section. Related: What domains should I add to my allowlist?

EnableOrganization > Claude in Chrome > Enable for your Team

Allow team members to use the Claude in Chrome extension. Configure site permissions after enabling. This enables the Claude in Chrome connector, which allows Claude to navigate and operate the user’s Chrome browser.

Set ‘Allow extension’Organization > Claude in Chrome > Default for all sites > Allow/Deny Extension

This will configure Claude in Chrome so that sites are allowed by default, unless they are explicitly added to the ’Blocked sites’ list.

ConfigureOrganization > Claude in Chrome > Blocked Sites

Claude in Chrome cannot be used on these websites. Add sensitive sites to the Blocked Sites list. It is recommended to block sites for which the user operates with a high level of privilege and sites that are likely to process highly sensitive data (e.g., password managers, billing pages for apps used in the organization, etc.) Note: during testing, the blocklist did not appear to restrict access.

EnableOrganization > Libraries > Connectors > Desktop Extension Allowlist

Limit the extensions that your team can install on their desktop. When enabled, users can only install desktop extensions that have been added to the list above. Via this allowlist, organizations should configure which desktop extensions they would like to allow. Note, ‘desktop extensions (DXT)’ are being renamed to MCP Bundles (MCPB). Related: The Risks of Connectors in Your AI Applications

ConfigureOrganization > Libraries > Connectors > Add

DisableOrganization > Cowork > Permissions > Allow "Act without asking" mode

When enabled, users can let Claude act without asking for approval—including using tools, editing files, and browsing websites. This can put organizational data at risk. Disable this setting — when 'always allow' is available, prompt injections can manipulate Claude to take sensitive actions on websites or perform destructive operations on local files in the connected Cowork folder without user consent.

DisableOrganization > Cowork > Permissions > Allow “Always allow” for connector tools

Let members choose "Always allow" when approving connector tools in Cowork. This increases risk from prompt injection — content from connected apps could cause Claude to take unintended actions without per-use approval. Learn more Disable this setting — when 'always allow' is available, prompt injections can manipulate Cowork to take actions via connectors without any opportunity for user approval.

DisableOrganization > Privacy Settings > Public Projects

All users in an organization can see and start chats in public projects. This will prevent users from creating chats with Cowork that leverage data from public projects.

EnableOrganization > Capabilities > Data Sources > Ask Organization

Allow your team members to search across your organization's connected data sources and knowledge bases for more comprehensive results. This will allow users to open Cowork chats based on trusted data from the Ask Organization interface. Note, in the real UI, this setting uses your organization name, e.x, “Ask PromptArmor”.

Settings for Claude Chat Only

DisableOrganization > Privacy Settings > Location Metadata

The risk of Claude having user-level metadata on location does not outweigh any benefits from localization; by turning it off, it allows users to determine when they want to share location-level data (e.g. via the chat) rather than having it by default

DisableOrganization > Privacy Settings > Share chats

Sharing chats increases the risk of data exposure between users of different privileges (although sharing is restricted to within the same organization.

DisableOrganization > Privacy Settings > Share Chats That Use Connectors

Disallows people from sharing chats that use connectors with others in your org. Recipients will see Claude's response, but not the data from the connector. Sharing chats increases the risk of data exposure outside of your tenant.

EnableOrganization > Capabilities > Claude Design

Allow team members to access Claude Design.

DisableOrganization > Claude in Slack > Allow Claude in Slack

Let members of your organization connect Claude to your Slack workspace and use the Claude bot.

Tier 3: Locked Down

Tier 3 prioritizes security above all else, disabling most dynamic or external-facing capabilities. Claude operates as a mostly self-contained assistant with no access to external data, executable code, or connected services. Prompt injection surface is minimal.

What's disabled:

  • Code execution and file creation (cloud) — no server-side code execution and file creation

  • Network egress — no package installs or external domain access from the sandbox

  • Skills — All skills blocked, including user-uploaded skills, and skill sharing is prohibited

  • Plugins — user-uploaded plugins blocked

  • Connectors and desktop extensions — no external service integrations

  • Always allow mode for connectors — prohibited, encouraging human in the loop approval

  • Skip all approvals mode — prohibited, encouraging human in the loop approval

  • Claude in Chrome — no browser automation

  • Ask Organization — users cannot access or start chats based on data from ‘Ask Organization’

  • Public Projects — users cannot access or start chats in shared projects

  • M365 Integration — users cannot orchestrate Claude in Excel or PowerPoint from Cowork

  • Claude in Design — disallowed reducing risk of injections or malicious code in externally-sourced assets

  • Claude in Slack — disallowed, limiting ingest of varied trust level data sources

  • Dispatch agents — disabled, preventing autonomous agents from interacting with one's computer without substantial oversight

What's enabled:

  • OTel monitoring — full observability with no functionality impact

  • Local Cowork operations — remain available (file access and chat attachments are user-level controls, not disabled by default)

Additional Controls and NIST Mappings

Beyond the Cowork-specific configurations above, the following infrastructure controls determine whether your tier configuration is actually enforceable. Without identity, access, monitoring, and data governance controls in place, even a Tier 3 lockdown can be circumvented; for example, by users switching to personal accounts.

These action items should be implemented regardless of which tier is selected, then combined with the tier-specific Cowork configurations.
