## Verdict summary
**Blocked & quarantined** — The remote server can supply a native executable that is installed into the consumer dependency tree and executed when the CLI is used.

- **Verdict:** Malicious
- **Product-default install policy:** Block
- **Firewall policy:** Matched malicious
- **Public report status:** Published
- **Threat category:** Install Hook Abuse
- **Selected version:** 1.14.50-202609141712
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. 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.

Installation downloads an unverified native archive from a fixed IP address while disabling TLS certificate validation. It extracts and marks the supplied binary executable; the onecode launcher later spawns it.

## Security analysis

### Published attack-surface review

- **Summary:** Installation downloads an unverified native archive from a fixed IP address while disabling TLS certificate validation. It extracts and marks the supplied binary executable; the onecode launcher later spawns it.

- **Trigger:** npm installation, followed by running the onecode command

- **Impact:** The remote server can supply a native executable that is installed into the consumer dependency tree and executed when the CLI is used.

- **Evidence paths:** package.json, postinstall.mjs, platform-bootstrap.mjs, bin/onecode

- **Review source:** ai\_review

- **Reviewed:** 2026-09-14T09:19:45.751Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Postinstall remote native payload download, extraction, and launcher execution

- **Attack narrative:** On installation, the package runs its bootstrapper automatically. The bootstrapper fetches a versioned archive from a hard-coded IP address with certificate validation disabled, extracts it into node\_modules, and marks its native binary executable. The shipped launcher selects that cached binary and spawns it when the user runs onecode. This gives the remote host control over executable code placed in the consumer installation without a source-visible integrity check.

- **Rationale:** This is an automatic lifecycle-based remote native payload installer that disables TLS verification and has no visible integrity validation. The later launcher execution completes a concrete remote code delivery path.

- **Files touched:** package.json, postinstall.mjs, platform-bootstrap.mjs, node\_modules/onecode-linux-x64/bin/onecode, bin/.onecode, bin/onecode

- **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., The postinstall script invokes the platform bootstrapper., The bootstrapper downloads an archive from a hard-coded IP address with TLS certificate checks disabled., The downloaded archive is extracted into node\_modules, its binary is made executable, and the launcher spawns that binary.

- **Evidence against:** No source in this snapshot directly harvests credentials or uploads local files., The postinstall script does not directly execute the downloaded binary.

## Affected versions and remediation

This report applies to @onescience/onecode@1.14.50-202609141712.

- Avoid installing @onescience/onecode@1.14.50-202609141712. 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.
