## Security analysis

### Published attack-surface review

- **Summary:** npm postinstall can retrieve and install an unverified native executable outside npm integrity controls. The fetched executable is subsequently launched by the onecode command.

- **Trigger:** npm install, followed by invoking the onecode bin command

- **Impact:** A network or server attacker can substitute arbitrary native code that users later execute.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-09T22:32:47.731Z

### AI review details

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

- **Mechanism:** TLS-bypassed remote native archive download, extraction, and binary installation

- **Rationale:** The source establishes a serious unverified remote-native-payload install chain, but does not establish that the payload itself performs malicious actions or that installation mutates a foreign/broad AI-agent control surface.

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

- **Network endpoints:** https://218.90.133.98:4443/onecode\_tgz/onecode-1.14.50-202608061753/onecode-linux-x64-1.14.50-202608061753.tgz

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 96.0%

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

- **Intent class:** Critical Vulnerability

- **False-positive risk:** Low

- **Evidence for:** package.json runs postinstall.mjs on npm install., platform-bootstrap.mjs downloads a versioned archive from a fixed IP and disables TLS verification., Downloaded archive is extracted with tar and its executable is chmodded and linked as bin/.onecode., Redirects are followed without validating destination; no checksum/signature verification exists.

- **Evidence against:** No credential harvesting, environment exfiltration, or destructive host actions found., The launcher only runs the installed platform binary when the user invokes onecode., Asset links target this package's own root, not a foreign global agent configuration.

## Public findings

### 1. High: Install Time Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 90.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@onescience/onecode@1.14.50-202608061753/package.json>)

- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/@onescience/onecode@1.14.50-202608061753/package.json>)

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@1.14.50-202608061753/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@1.14.50-202608061753/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. High: Previous Version Dangerous Delta
- **Category:** Supply Chain
- **Confidence:** 93.0%
- **Path:** bin/onecode
- **Public source:** [View source](<https://unpkg.com/@onescience/onecode@1.14.50-202608061753/bin/onecode>)

This package version adds a dangerous source file absent from the previous stored version; route for source-aware review.

Public source snippet (untrusted):

```text
matchType = previous_version_dangerous_delta
matchedPackage = @onescience/onecode@1.14.50-202607171833
matchedIdentity = npm:QG9uZXNjaWVuY2Uvb25lY29kZQ:1.14.50-202607171833
similarity = 1.000
summary = stored previous version shares package body but lacks this dangerous source file
```
