## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall fetches and installs a remotely supplied native executable without certificate or content verification. The executable is subsequently launched by the onecode CLI.

- **Trigger:** npm installation, followed by invoking onecode

- **Impact:** A network attacker or compromised payload host can replace the installed executable and obtain code execution as the installing user.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-09T22:37:59.218Z

### AI review details

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

- **Mechanism:** TLS-bypassed remote native payload download and launcher installation

- **Rationale:** Inspected source establishes an unsafe install-time remote native payload chain, but does not establish intentional theft, destruction, or foreign AI-agent control-surface mutation. This is a concrete critical vulnerability requiring a warning.

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

- **Network endpoints:** https://218.90.133.98:4443/onecode\_tgz/onecode-1.14.50-202608051418/onecode-linux-x64-1.14.50-202608051418.tgz

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 98.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Critical Vulnerability

- **False-positive risk:** Low

- **Evidence for:** package.json runs postinstall.mjs on install., platform-bootstrap.mjs downloads an unsigned native tgz from a fixed IP., HTTPS verification is disabled with rejectUnauthorized: false., The downloaded archive is extracted into node\_modules and its binary is linked for execution.

- **Evidence against:** No credential harvesting or exfiltration appears in inspected source., Filesystem writes target this package and its platform dependency, not a foreign global agent configuration., bin/onecode launches the installed platform binary only when the CLI is invoked.

## Public findings

### 1. High: Install Time Lifecycle Scripts

Install-time lifecycle script is not statically allowlisted and needs review.

Public source snippet (untrusted):

```json
scripts.postinstall = node ./postinstall.mjs
```

### 3. Low: Scripts Present
- **Category:** Manifest
- **Confidence:** 100.0%

Package declares npm scripts.

### 4. Medium: Network
- **Category:** Source
- **Confidence:** 75.0%

Package source references network APIs.

### 7. High: Unverified Remote Native Payload Install
- **Category:** Source
- **Confidence:** 94.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@onescience/onecode@1.14.50-202608051418/package.json>)

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
L79: const binaryPath = path.join(rootDir, "node_modules", packageName, "bin", binaryName)
L80: if (!fs.existsSync(binaryPath)) return null
L81: return { binaryPath, binaryName, packageName }
L82: }
...
L99: return new Promise((resolve, reject) => {
```

### 8. Low: Url Strings
- **Category:** Supply Chain
- **Confidence:** 65.0%

Package source contains URL literals.

### 9. High: Known Malware Source Similarity
- **Category:** Static
- **Confidence:** 97.0%
- **Path:** platform-bootstrap.mjs
- **Public source:** [View source](<https://unpkg.com/@onescience/onecode@1.14.50-202608051418/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
