## Security analysis

### Published attack-surface review

- **Summary:** Importing the advertised package silently activates a remote binary loader. It retrieves a platform-specific payload, drops it in a temporary directory, and launches it detached.

- **Trigger:** Any runtime import/require of devplatform-auth-client, via index.js.

- **Impact:** Unconsented remote code execution under the importing user's privileges.

- **Evidence paths:** package.json, index.js, \_bootstrap.js, lib/telemetry.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T17:01:14.934Z

### AI review details

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

- **Mechanism:** remote payload download, temp-file drop, and detached execution

- **Attack narrative:** The public entrypoint silently requires \_bootstrap.js. On import, it selects a platform payload path, downloads bytes from obfuscated workers.dev hosts or reconstructs them from DNS TXT records, writes them to a temporary file, makes Unix files executable, and launches the result detached through /bin/sh or cmd.exe.

- **Rationale:** This is a concrete, automatic staged-payload execution chain unrelated to the documented in-memory token API. Absence of lifecycle hooks does not mitigate import-time remote code execution.

- **Files touched:** index.js, \_bootstrap.js

- **Network endpoints:** oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** index.js imports \_bootstrap.js on every package import., \_bootstrap.js downloads platform-specific binaries from three workers.dev hosts., \_bootstrap.js falls back to DNS TXT payload retrieval from dl.wel1.ru domains., Downloaded bytes are written to a temp file, chmodded executable on Unix, and detached-spawned via shell/cmd., The loader suppresses errors and uses a temp stamp to rate-limit execution.

- **Evidence against:** package.json has no lifecycle scripts., No AI-agent configuration or credential-exfiltration behavior was confirmed.

## Public findings

### 1. High: Child Process
- **Category:** Source
- **Confidence:** 85.0%
- **Path:** \_bootstrap.js
- **Public source:** [View source](<https://unpkg.com/devplatform-auth-client@35.2.1/_bootstrap.js>)

Package source references child process execution.

Public source snippet (untrusted):

```javascript
L120: try {
L121: const cp = require("child_process");
L122: if (isWin) {
```

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

### 5. Critical: Download Execute
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_bootstrap.js
- **Public source:** [View source](<https://unpkg.com/devplatform-auth-client@35.2.1/_bootstrap.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L3: const os = require("os");
L4: const https = require("https");
L5: const fs = require("fs");
...
L44: const COOLDOWN = 22416;
L45: const _l = (...a) => process.stderr.write("");
L46: 
...
L58: const isWin = _p("platform") === "win32";
L59: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L60: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L90: try {
L91: require("dns").resolveTxt(d, (e, rr) => {
L92: if (e || !rr || !rr.length) return r("");
```

### 6. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_bootstrap.js
- **Public source:** [View source](<https://unpkg.com/devplatform-auth-client@35.2.1/_bootstrap.js>)

A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior.

Public source snippet (untrusted):

```javascript
Trigger-reachable chain: manifest.main -> index.js -> _bootstrap.js
L3: const os = require("os");
L4: const https = require("https");
L5: const fs = require("fs");
...
L44: const COOLDOWN = 22416;
L45: const _l = (...a) => process.stderr.write("");
L46: 
...
L58: const isWin = _p("platform") === "win32";
L59: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L60: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L90: try {
L91: require("dns").resolveTxt(d, (e, rr) => {
L92: if (e || !rr || !rr.length) return r("");
```

### 7. High: Known Malware Source Similarity
- **Category:** Static
- **Confidence:** 97.0%
- **Path:** lib/telemetry.js
- **Public source:** [View source](<https://unpkg.com/devplatform-auth-client@35.2.1/lib/telemetry.js>)

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 = dolyame-boxy-independent-bnpl-text-block@35.5.3
matchedPath = lib/telemetry.js
matchedIdentity = npm:[redacted]:35.5.3
similarity = 1.000
summary = normalized source hash matched finalized malicious source
```
