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. Installing the package automatically retrieves a native archive from a fixed remote host with TLS verification disabled. The archive is extracted into node\_modules and made executable without a checksum or signature verification. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-21T10:26:25.926Z - **Finished:** 2026-09-21T10:36:21.665Z - **Download time:** 765 ms - **Static scan time:** 43 ms - **AI review time:** 594931 ms - **Total time:** 595739 ms The recorded confidence comes from the underlying analysis.

The archive is extracted into node\_modules and made executable without a checksum or signature verification. - **Trigger:** npm postinstall during package installation. - **Impact:** A network attacker or the remote host can supply an unverified native payload that will be available to the installed CLI. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-21T10:36:21.665Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall calls the bootstrapper, which downloads a platform tarball, extracts it with tar, and installs its binary. - **Rationale:** Automatic installation of an unverified native payload with disabled TLS validation is a concrete supply-chain risk. The snapshot does not itself prove the remote payload's malicious content or execution, so a warning is appropriate rather than a block. - **Files touched:** package.json, postinstall.mjs, platform-bootstrap.mjs, node\_modules, 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:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package automatically runs a postinstall script., The postinstall script invokes the platform bootstrapper., The bootstrapper defaults to a fixed IP-address HTTPS host and disables TLS certificate validation., It downloads, extracts, and installs a native platform archive without an integrity check. - **Evidence against:** The inspected launcher only resolves and runs the installed platform binary; no credential harvesting or data-exfiltration code was found in this snapshot., The remote archive contents are not present in the package, so its payload cannot be confirmed by static inspection. ## Affected versions and remediation This report applies to @onescience/onecode@1.14.50-202609211543. - Review the evidence and your use of @onescience/onecode@1.14.50-202609211543 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.
