The package installs and exposes that archive's binary for execution when the onecode CLI is run. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 96.0% - **Started:** 2026-08-09T22:31:57.844Z - **Finished:** 2026-08-09T22:33:05.582Z - **Download time:** 767 ms - **Static scan time:** 43 ms - **AI review time:** 66927 ms - **Total time:** 67738 ms ## Security analysis ### Published attack-surface review - **Summary:** npm install fetches an unverified native archive from a fixed external IP with TLS certificate validation disabled. The package installs and exposes that archive's binary for execution when the onecode CLI is run. - **Trigger:** npm install, followed by invoking onecode - **Impact:** A network attacker or remote host operator can replace the native executable users later run. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs, bin/onecode - **Review source:** ai\_review - **Reviewed:** 2026-08-09T22:33:05.582Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall remote native-payload download, extraction, and launcher linking - **Rationale:** The source establishes a real unverified remote-native-payload delivery path, but the extracted payload is unavailable here, so concrete malicious behavior beyond that delivery mechanism cannot be established. - **Files touched:** postinstall.mjs, platform-bootstrap.mjs, bin/.onecode, node\_modules/onecode-\-\, .platform-bootstrap-work, .platform-version, .opencode, .oneskills - **Network endpoints:** https://218.90.133.98:4443/onecode\_tgz ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Critical Vulnerability - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall.mjs on npm install., platform-bootstrap.mjs downloads an archive from 218.90.133.98:4443 during postinstall., Download disables TLS verification and accepts redirects without integrity verification., Downloaded archive is extracted and its native binary is installed, linked, and later launched by bin/onecode. - **Evidence against:** No credential harvesting or outbound data-exfiltration code found., No source evidence of destructive actions or writes outside this package installation., Agent-related directories are linked under the package root, not a foreign user control surface. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts.
