A network attacker or archive host compromise can stage arbitrary executable content for later user invocation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 96.0% - **Started:** 2026-08-09T22:31:57.851Z - **Finished:** 2026-08-09T22:32:47.597Z - **Download time:** 761 ms - **Static scan time:** 40 ms - **AI review time:** 48944 ms - **Total time:** 49746 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall fetches an unauthenticated remote native archive, extracts it into node\_modules, and exposes its binary through the package launcher. A network attacker or archive host compromise can stage arbitrary executable content for later user invocation. - **Trigger:** npm installation on non-Windows when the platform package is absent. - **Impact:** Unverified native executable is installed and later launched by bin/onecode. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs, bin/onecode - **Review source:** ai\_review - **Reviewed:** 2026-08-09T22:32:47.597Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** TLS-bypassed remote native payload download and installation - **Rationale:** The package creates a concrete install-time remote-payload supply-chain risk, but inspected source does not establish exfiltration, destructive action, or foreign AI-agent control-surface mutation. This warrants a warning rather than a malicious block under the stated policy. - **Files touched:** postinstall.mjs, platform-bootstrap.mjs, node\_modules/onecode-\-\/, bin/.onecode, .platform-version, .platform-bootstrap-work, .opencode, .oneskills, bin/onecode - **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 install., platform-bootstrap.mjs downloads a platform archive from a fixed IP address., TLS validation is disabled with rejectUnauthorized:false., Downloaded archive has no hash/signature verification before extraction., Postinstall extracts the archive and installs/chmods its native binary. - **Evidence against:** No credential, environment, or user-file harvesting is present in inspected source., No source evidence of exfiltration or execution of the downloaded binary during postinstall., Writes are scoped to this package's node\_modules, bin/.onecode, and package asset links. ## 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.

High: Unverified Remote Native Payload Install - **Category:** Source - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() Install-time source downloads a native archive from a fixed external host without transport verification, extracts it, and installs an executable payload. Public source snippet (untrusted): ```json scripts.postinstall = node ./postinstall.mjs Install-time code downloads an unverified remote native archive, stages it locally, activates an executable path, and exposes it to process execution.
