Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The source confirms automatic installation metadata reporting and runtime forwarding of local server exchanges to the package's telemetry service. The product-aligned, disclosed destination does not establish malicious intent, but the request and response capture warrants a warning. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-28T22:18:41.459Z - **Finished:** 2026-10-28T22:20:16.596Z - **Download time:** 2051 ms - **Static scan time:** 2252 ms - **AI review time:** 90833 ms - **Total time:** 95137 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:** The runtime can disclose local Slack server request and response contents through telemetry. The destination is Portomatic's collector by default, and token redaction retains the first eight characters. - **Trigger:** The emulator's HTTP server handles requests while telemetry is configured. - **Impact:** Local API content and partial token or secret values may be disclosed to the telemetry recipient. - **Evidence paths:** products/slack/dist/src/http/server.js, products/slack/dist/src/telemetry/http.js, lib/telemetry/client/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-28T22:20:16.596Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The server captures request and response bodies and submits telemetry batches to the configured endpoint, defaulting to telemetry.portomatic.com. - **Rationale:** The source confirms automatic installation metadata reporting and runtime forwarding of local server exchanges to the package's telemetry service. The product-aligned, disclosed destination does not establish malicious intent, but the request and response capture warrants a warning. - **Files touched:** products/slack/dist/src/http/server.js, products/slack/dist/src/telemetry/http.js, lib/telemetry/client/index.js - **Network endpoints:** https://telemetry.portomatic.com/v1/events ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs bin/install.mjs automatically after installation., The install hook reports operating system, architecture, Node version, environment classification, and package manager, then flushes telemetry., Telemetry records device and session identifiers and posts batches to telemetry.portomatic.com by default; an environment variable can override the endpoint., The local HTTP server passes each request to a capture helper that records request and response bodies for telemetry., Token-like values are redacted to their first eight characters, which leaves a partial credential and does not prevent transfer of other request or response content., The README discloses Portomatic telemetry and states that local server requests and responses are sent to the collector. - **Evidence against:** The telemetry destination is Portomatic's product-branded collector, and the README discloses the collection., The install event contains environment metadata; the inspected hook does not collect project files or credentials. ## Affected versions and remediation This report applies to portomatic@0.3.74. - Review the evidence and your use of portomatic@0.3.74 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
