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 package automatically sends device-linked install metadata and captured local HTTP exchange content to its product telemetry service, creating a concrete data exposure risk. The collector is package-aligned and the runtime discloses the collection, so the evidence supports a warning rather than a malware block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-29T00:27:33.846Z - **Finished:** 2026-10-29T00:33:18.268Z - **Download time:** 1809 ms - **Static scan time:** 2114 ms - **AI review time:** 340498 ms - **Total time:** 344422 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:** Automatic telemetry exposes host metadata and local emulator HTTP request and response content to the product telemetry service. The source shows a disclosure and partial secret redaction, but no opt-in gate for this collection. - **Trigger:** Package installation runs the postinstall hook; starting the emulator activates HTTP exchange capture. - **Impact:** The service receives device-linked installation metadata and potentially sensitive local request and response content; secret-like values are shortened to eight characters. - **Evidence paths:** package.json, bin/install.mjs, lib/telemetry/client/index.js, lib/telemetry/client/identity.js, products/slack/dist/src/http/server.js, products/slack/dist/src/telemetry/http.js, products/slack/dist/src/emulator.js - **Review source:** ai\_review - **Reviewed:** 2026-10-29T00:33:18.268Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The installer emits environment metadata, while the local HTTP server records request and response details for telemetry batches sent to the default service endpoint. - **Rationale:** The package automatically sends device-linked install metadata and captured local HTTP exchange content to its product telemetry service, creating a concrete data exposure risk. The collector is package-aligned and the runtime discloses the collection, so the evidence supports a warning rather than a malware block. - **Files touched:** .portomatic/device\_id, .portomatic/npm-version - **Network endpoints:** https://telemetry.portomatic.com/v1/events ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest runs bin/install.mjs during postinstall, where the package emits install metadata and flushes telemetry., Install telemetry includes operating system, architecture, Node version, CI status, and package manager. The client links events to a persistent device identifier., The local HTTP server captures requests and responses, including URLs, headers, and bodies, and emits them as telemetry events., The client posts telemetry batches to https://telemetry.portomatic.com/v1/events by default., The client prints a first-run notice describing device-linked telemetry and request/response collection; its redaction keeps the first eight characters of sensitive values. The flagged suggested-prompts method is gated on an app manifest feature and an explicit API operation. - **Evidence against:** The recipient is Portomatic's product telemetry service, and the runtime prints a disclosure. The source truncates sensitive values instead of sending them intact; these facts reduce the concern but do not prevent request and response content from being collected. ## Affected versions and remediation This report applies to portomatic@0.3.75. - Review the evidence and your use of portomatic@0.3.75 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.
