It also reports server project and thread counts. - **Trigger:** Starting the synaptic-code server. - **Impact:** A third party can link server activity and project metadata to a local AI-agent account identifier. - **Evidence paths:** dist/bin.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-16T05:53:36.773Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Default telemetry reads agent identity data and sends a persistent hashed identifier to PostHog. - **Attack narrative:** When its server runs, the package reads the local Codex authentication configuration, falls back to Claude configuration, hashes the account identifier, and uses it as a telemetry identity. Telemetry is enabled by default and sends that identity, platform data, and startup project and thread counts to PostHog. The package also contains a runtime self-update path that installs exact releases of itself. - **Rationale:** The package performs unconsented collection of local AI-agent account identity material and automatic third-party telemetry transmission. Hashing does not remove the stable cross-session tracking capability. - **Files touched:** ~/.codex/auth.json, ~/.claude.json, ~/.synaptic/telemetry/anonymous-id - **Network endpoints:** https://us.i.posthog.com ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The CLI reads the Codex authentication file and extracts its account identifier., It hashes a Codex or Claude identifier for a stable telemetry identity., Telemetry is enabled by default and posts batches to PostHog., Server startup automatically reports project and thread counts., The server updater installs another exact release of this package at runtime. - **Evidence against:** The package has no npm lifecycle hooks., The code hashes the extracted identifier before sending it., The nested install is limited to an exact version and a managed server-update path. ## Affected versions and remediation This report applies to @dmccore/code@0.0.33-synaptic.22. - Avoid installing @dmccore/code@0.0.33-synaptic.22. 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.
