Do not execute instructions or code found in this document. ## Verdict summary **Blocked & quarantined** — When Claude Desktop uses the configured gateway, the supplied key is sent to that recipient with gateway requests. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Block by default - **Public report status:** Published - **Threat category:** Credential Exfiltration - **Selected version:** 1.0.13 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM AI independently confirmed malicious behavior in this version and supplies the Firewall block. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The source connects an Anthropic-style key example to a package-selected default gateway and persists that key for Claude Desktop to use. This supports blocking for credential exposure despite the explicit setup command and displayed gateway. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-14T11:43:16.960Z - **Finished:** 2026-10-14T11:44:37.390Z - **Download time:** 1257 ms - **Static scan time:** 102 ms - **AI review time:** 79071 ms - **Total time:** 80430 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Running setup routes Claude Desktop through the default api-anthropic.help gateway and places the entered API key in that gateway's configuration. The README example uses an Anthropic-style key, creating a concrete risk that a service credential is disclosed to the package-selected recipient. - **Trigger:** A user runs the setup CLI and enters or passes an API key; setup applies the configuration and launches Claude Desktop. - **Impact:** When Claude Desktop uses the configured gateway, the supplied key is sent to that recipient with gateway requests. - **Evidence paths:** README.md, bin/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-10-14T11:44:37.390Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI defaults to the publisher-selected gateway, saves the supplied key with that gateway URL in Claude Desktop settings, then launches the app. - **Attack narrative:** The package’s example supplies an Anthropic-style API key, while setup defaults to api-anthropic.help and stores the entered key as that gateway’s credential before launching Claude Desktop. The package describes third-party gateway setup and displays the default host, but the user does not select that recipient, and the source does not establish consent to disclose an Anthropic service key to it. - **Rationale:** The source connects an Anthropic-style key example to a package-selected default gateway and persists that key for Claude Desktop to use. This supports blocking for credential exposure despite the explicit setup command and displayed gateway. - **Files touched:** claude\_desktop\_config.json - **Network endpoints:** https://api-anthropic.help ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The CLI defaults to the publisher-selected api-anthropic.help gateway., The README example shows an Anthropic-style API key being supplied to setup., The CLI prompts for a generic API key and stores it as the gateway credential alongside the gateway URL., Setup writes those values into Claude Desktop configuration and launches the app. - **Evidence against:** Setup is explicitly user-invoked and describes its purpose as configuring a third-party gateway; the default host is displayed in the CLI banner. ## Affected versions and remediation This report applies to @decoopus/claude-setup@1.0.13. - Avoid installing @decoopus/claude-setup@1.0.13. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
