The resulting stable SHA-256 identifier and runtime metadata are sent to PostHog. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 93.0% - **Started:** 2026-08-18T02:35:07.403Z - **Finished:** 2026-08-18T02:37:09.248Z - **Download time:** 2294 ms - **Static scan time:** 33593 ms - **AI review time:** 85958 ms - **Total time:** 121845 ms ## Security analysis ### Published attack-surface review - **Summary:** Running the CLI reads third-party AI-client identity files and uses their identifiers for default-on telemetry. The resulting stable SHA-256 identifier and runtime metadata are sent to PostHog. - **Trigger:** User runs synaptic-code and starts its server runtime. - **Impact:** Links usage telemetry to a Codex or Claude account-derived identifier without an explicit opt-in. - **Evidence paths:** package.json, dist/bin.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-18T02:37:09.248Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** default-on account-derived telemetry exfiltration - **Attack narrative:** The executable prioritizes extracting an account ID from ~/.codex/auth.json or a user ID from ~/.claude.json, hashes it, and uses it as telemetry distinct\_id. Telemetry is enabled by default and a startup heartbeat records usage metadata before posting batches to PostHog. This is not install-time behavior, but it is a concrete runtime collection and third-party transmission path involving foreign AI-client account data. - **Rationale:** The package implements default-on transmission of identifiers derived from foreign Codex/Claude authentication files, rather than using only its own anonymous identifier. Hashing does not remove the stable cross-session tracking capability. - **Files touched:** ~/.codex/auth.json, ~/.claude.json, ~/.synaptic/telemetry/anonymous-id, dist/bin.mjs - **Network endpoints:** https://us.i.posthog.com/batch/ ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Reads Codex auth.json and extracts tokens.account\_id., Uses Codex/Claude account identifiers before an anonymous fallback., Telemetry is enabled by default and targets PostHog., Sends the derived identifier as distinct\_id to PostHog., Records a startup heartbeat automatically. - **Evidence against:** No npm preinstall, install, or postinstall hook., Identifiers are SHA-256 hashed before transmission., No source evidence of archiving configs or publishing data to npm. ## Public findings ### 1.
