Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 21 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Telemetry warning (can be blocked) - **Public report status:** Published - **Threat category:** Telemetry - **Selected version:** 0.3.80 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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 default postinstall sends install and update telemetry to the package’s own service, so this is warning-level telemetry under the review policy. The reviewed fields are limited to package and runtime metadata; no credential theft or other attack behavior was identified. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-11-03T00:11:59.770Z - **Finished:** 2026-11-03T00:13:03.963Z - **Download time:** 1011 ms - **Static scan time:** 6502 ms - **AI review time:** 56679 ms - **Total time:** 64193 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:** Default install-time telemetry reports package and environment metadata to the package’s collector, linked to a random device ID and source IP. - **Trigger:** npm postinstall. - **Impact:** The publisher receives install metadata without a separate install-time request from the user; this is a privacy risk, but the reviewed fields do not include credentials or project contents. - **Evidence paths:** package.json, bin/install.mjs, lib/telemetry/client/index.js, lib/telemetry/client/identity.js - **Review source:** ai\_review - **Reviewed:** 2026-11-03T00:13:03.963Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** bin/install.mjs emits install and, when applicable, update events; the telemetry client sends queued events over HTTPS. - **Rationale:** The default postinstall sends install and update telemetry to the package’s own service, so this is warning-level telemetry under the review policy. The reviewed fields are limited to package and runtime metadata; no credential theft or other attack behavior was identified. - **Files touched:** ~/.portomatic/device\_id, ~/.portomatic/first\_run\_pending, ~/.portomatic/npm-version - **Network endpoints:** telemetry.portomatic.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 97.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package postinstall hook automatically runs bin/install.mjs., The install script reports OS, architecture, Node version, CI status, launch type, package manager, and version-change metadata., Telemetry is POSTed to telemetry.portomatic.com by default; the code describes collection linked to a random device ID and the sender’s IP address., The device ID is generated as a UUID and persisted locally. - **Evidence against:** The install event fields are limited to runtime and package-manager metadata; the reviewed install code does not send credential values., The telemetry code describes shaping and redacting collected data, including credentials., The package’s stated purpose is local third-party app sandboxes for agents. ## Affected versions and remediation This report applies to portomatic@0.3.80. - Review the evidence and your use of portomatic@0.3.80 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.
