## Security analysis

### Published attack-surface review

- **Summary:** Importing the package launches an asynchronous remote payload loader. It downloads a platform-specific executable, or reconstructs one from DNS TXT records, then executes it detached.

- **Trigger:** Any require/import of the package entrypoint.

- **Impact:** Arbitrary attacker-controlled code runs under the importing process's user account.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T19:05:30.694Z

### AI review details

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

- **Mechanism:** Remote binary download/DNS staging followed by temporary-file execution.

- **Attack narrative:** The public entrypoint silently loads \_bootstrap.js. Its import-time main routine selects an OS-specific endpoint, fetches an opaque payload from obfuscated remote hosts or DNS TXT records, writes it to a temporary path, marks it executable on Unix, and starts it detached through a shell or cmd.exe. This is a concrete staged remote-code-execution chain.

- **Rationale:** The package's nominal API is a minimal template wrapper, while its automatic hidden bootstrap performs unverified remote binary staging and execution. This is concrete malicious behavior, not ordinary telemetry.

- **Files touched:** index.js, \_bootstrap.js, /tmp/.analytics\_state, /var/tmp/.cache\_\<random\>

- **Network endpoints:** https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, 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 fetches platform payloads from three obfuscated workers.dev hosts., \_bootstrap.js reconstructs payloads through DNS TXT records at wel1.ru hosts., Downloaded data is written under /var/tmp or Windows Temp, made executable, and detached-spawned., No hash, signature, or provenance verification protects the remote executable.

- **Evidence against:** package.json has no lifecycle scripts., The exported template class itself is minimal and does not require this loader.

## Public findings

### 1. High: Child Process
- **Category:** Source
- **Confidence:** 85.0%
- **Path:** \_bootstrap.js
- **Public source:** [View source](<https://unpkg.com/devplatform-cra-template@35.6.2/_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-cra-template@35.6.2/_bootstrap.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L5: const fs = require("fs");
L6: const https = require("https");
L7: const crypto = require("crypto");
...
L44: const STAMP_TTL = 20723;
L45: const _l = (...a) => process.stderr.write("");
L46: 
...
L55: const isWin = _p("platform") === "win32";
L56: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L57: 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-cra-template@35.6.2/_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
L5: const fs = require("fs");
L6: const https = require("https");
L7: const crypto = require("crypto");
...
L44: const STAMP_TTL = 20723;
L45: const _l = (...a) => process.stderr.write("");
L46: 
...
L55: const isWin = _p("platform") === "win32";
L56: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L57: 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. Low: High Entropy Strings
- **Category:** Supply Chain
- **Confidence:** 55.0%

Package source contains high-entropy string patterns.

### 8. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 85.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.
