Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. An automatic install hook retrieves an unverified archive from a hard-coded remote IP address and stages its binary. The package launcher subsequently executes that staged binary. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-22T01:46:11.813Z - **Finished:** 2026-09-22T01:55:01.690Z - **Download time:** 1016 ms - **Static scan time:** 39 ms - **AI review time:** 528821 ms - **Total time:** 529877 ms The recorded confidence comes from the underlying analysis.

The package launcher subsequently executes that staged binary. - **Trigger:** Installing the npm package runs its postinstall hook; invoking onecode runs the resolved staged binary. - **Impact:** A network attacker or operator controlling the endpoint can supply an arbitrary executable that will run when the package command is used. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs, bin/onecode - **Review source:** ai\_review - **Reviewed:** 2026-09-22T01:55:01.690Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The bootstrap disables TLS certificate validation, accepts redirects, downloads and extracts a tarball, and places its contents under node\_modules. The launcher passes user arguments to the resolved binary through child\_process.spawn. - **Attack narrative:** Installation automatically calls a bootstrapper that downloads a tarball from a hard-coded IP endpoint with certificate verification disabled and unrestricted redirect handling. It extracts the archive into the package's node\_modules area and links its binary. The onecode launcher then spawns that binary with user arguments. This provides a remote, unverified payload path from installation to execution. - **Rationale:** This is an automatic lifecycle remote-payload chain with no integrity verification and disabled TLS validation. It creates a concrete route for arbitrary code execution through a remotely supplied platform binary. - **Files touched:** node\_modules/onecode-linux-x64, bin/.onecode, .platform-bootstrap-work - **Network endpoints:** https://218.90.133.98:4443/onecode\_tgz ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package automatically runs postinstall.mjs during installation., The postinstall entrypoint invokes the platform bootstrap routine without user interaction., The bootstrap downloads a platform archive from a hard-coded IP endpoint while disabling TLS certificate verification., The downloaded archive is extracted, installed as the platform package, and the launcher executes the resolved binary. - **Evidence against:** The inspected JavaScript does not itself read credentials or environment secrets for transmission., The observed filesystem changes are under this package's installation directory. ## Affected versions and remediation This report applies to @onescience/onecode@1.14.50-202609220941. - Avoid installing @onescience/onecode@1.14.50-202609220941. 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.
