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. Installing the package automatically downloads an opaque native archive from a fixed IP address with certificate validation disabled. The archive is extracted into the package's node\_modules tree and its executable is selected by the launcher when onecode runs. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-17T00:51:13.036Z - **Finished:** 2026-09-17T00:52:01.669Z - **Download time:** 765 ms - **Static scan time:** 37 ms - **AI review time:** 47830 ms - **Total time:** 48633 ms The recorded confidence comes from the underlying analysis.

The archive is extracted into the package's node\_modules tree and its executable is selected by the launcher when onecode runs. - **Trigger:** npm installation, followed by running the onecode command - **Impact:** A network attacker or the remote host can supply a native executable that runs with the invoking user's privileges. - **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-17T00:52:01.669Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unverified remote native payload deployment through postinstall - **Attack narrative:** npm runs postinstall, which calls the bootstrapper. On a missing platform binary, the bootstrapper fetches a versioned archive from a hard-coded IP address with TLS verification disabled, follows redirects, extracts it, and places its native binary under node\_modules. The launcher later executes that binary. This creates an automatic, unauthenticated remote payload channel outside the reviewed npm tarball. - **Rationale:** This package creates a concrete automatic supply-chain payload path by accepting and deploying an opaque remote native binary without certificate or integrity verification. The lifecycle hook makes the behavior occur on installation without a separate user command. - **Files touched:** package.json, postinstall.mjs, platform-bootstrap.mjs, node\_modules/onecode-linux-x64/bin/onecode, bin/.onecode, .platform-bootstrap-work, .opencode, .oneskills - **Network endpoints:** https://218.90.133.98:4443/onecode\_tgz ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest automatically runs a postinstall script., Postinstall invokes the platform bootstrapper., The bootstrapper downloads an archive from a fixed IP address while disabling TLS certificate validation., It extracts the downloaded archive into node\_modules and makes its native binary executable., It also links package-provided .opencode and .oneskills assets into the launcher directory. - **Evidence against:** The inspected JavaScript contains no credential harvesting or exfiltration logic., The downloaded binary is not directly launched during postinstall; the launcher runs it when the onecode command is invoked., No runtime dependency on this package's own name appears in the manifest. ## Affected versions and remediation This report applies to @onescience/onecode@1.14.50-202608281720. - Avoid installing @onescience/onecode@1.14.50-202608281720. 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.
