Claude prompts and tool outputs can be captured and sent without an explicit setup command. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.14.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installation automatically alters Claude Code and VS Code AI telemetry configuration. It registers hook commands that collect session content and transmit traces to Flow. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-11T01:48:25.134Z - **Finished:** 2026-09-11T01:49:24.733Z - **Download time:** 759 ms - **Static scan time:** 737 ms - **AI review time:** 58102 ms - **Total time:** 59599 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:** Installation automatically alters Claude Code and VS Code AI telemetry configuration. It registers hook commands that collect session content and transmit traces to Flow. - **Trigger:** npm installation runs the postinstall lifecycle hook. - **Impact:** Claude prompts and tool outputs can be captured and sent without an explicit setup command. - **Evidence paths:** package.json, dist/setup.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T01:49:24.733Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic AI-agent configuration mutation and telemetry hook registration. - **Attack narrative:** Installing the package invokes its setup program automatically. Before any credential check, setup applies Claude Code hook configuration and detected VS Code Copilot telemetry configuration. The hooks execute this package on prompt and tool events; its runtime builds and sends observability traces containing prompt and tool-output material to the Flow service. This is an unconsented postinstall change to broad, foreign AI-agent control surfaces. - **Rationale:** The automatic lifecycle chain mutates Claude Code and VS Code AI configuration and enables telemetry hooks without a user setup command. This meets the install-control-surface blocking rule. - **Files touched:** package.json, dist/setup.js, ~/.claude/settings.json, VS Code User/settings.json - **Network endpoints:** https://flow.ciandt.com ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The postinstall hook automatically launches dist/setup.js., Setup immediately invokes configuration routines before checking for credentials., Those routines modify Claude Code hook settings and detected VS Code Copilot telemetry settings, a broad foreign AI control surface., The installed hooks capture Claude prompts and tool output and send traces to the Flow endpoint. - **Evidence against:** No self-dependency or downloaded executable payload is declared., The only fixed service host is the package-aligned Flow domain. ## Affected versions and remediation This report applies to @ciandt-flow/flow-ai-obs@0.14.0. - Avoid installing @ciandt-flow/flow-ai-obs@0.14.0. 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.
