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. An explicit CLI service-install operation creates a persistent per-user Synaptic Code server. No install-time mutation or credential-exfiltration chain was confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-08-20T17:12:36.426Z - **Finished:** 2026-08-20T17:14:52.266Z - **Download time:** 1530 ms - **Static scan time:** 33118 ms - **AI review time:** 101191 ms - **Total time:** 135840 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:** An explicit CLI service-install operation creates a persistent per-user Synaptic Code server. No install-time mutation or credential-exfiltration chain was confirmed. - **Trigger:** User runs synaptic-code service install or service update. - **Impact:** A background service restarts automatically and executes the package-managed server runtime. - **Evidence paths:** package.json, dist/bin.mjs, dist/service-launcher.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-20T17:14:52.266Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-level systemd persistence plus pinned npm runtime installation. - **Rationale:** This is not concrete malicious install-time behavior, but its explicit background-service persistence and runtime installation are sufficiently security-relevant to warn. No exfiltration or stealth execution was verified from source. - **Files touched:** dist/bin.mjs, dist/service-launcher.mjs, ~/.config/systemd/user/synaptic-code.service - **Network endpoints:** https://registry.npmjs.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for warning:** Explicit service install writes, enables, and starts a per-user systemd service with lingering., The generated unit restarts indefinitely and executes the package-managed launcher., Service setup installs an exact package version into its own runtime directory via npm. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The persistence path is a documented explicit CLI subcommand, not install-time behavior., No source evidence found of credential harvesting or exfiltration. ## Affected versions and remediation This report applies to @dmccore/code@0.0.33-synaptic.13. - Review the evidence and your use of @dmccore/code@0.0.33-synaptic.13 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.
