## Security analysis

### Published attack-surface review

- **Summary:** Importing the declared main entrypoint triggers a hidden downloader. It retrieves an unverified native payload, stores it in a temporary directory, and executes it detached.

- **Trigger:** require/import of the package main entrypoint

- **Impact:** Arbitrary remote code execution under the importing user's permissions.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-06T01:15:50.119Z

### AI review details

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

- **Mechanism:** remote binary download/DNS payload staging and detached execution

- **Attack narrative:** Requiring index.js silently loads \_bootstrap.js. Its async initializer selects a platform payload path, downloads bytes from hard-coded worker domains or reconstructs bytes from DNS TXT records, writes them as a temporary executable, chmods Unix payloads, then launches them detached through /bin/sh or cmd.exe. The hidden network hosts, payload staging, and execution are unrelated to the advertised minimal SDK.

- **Rationale:** The declared entrypoint performs concrete, automatic remote payload execution at import time. No install hook is needed for this to be a malicious RCE chain.

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

- **Network endpoints:** oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev/pkg/package, c.sdk.dl.wel1.ru, c.ext.dl.wel1.ru, c.pkg.dl.wel1.ru, c.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 binaries from obfuscated worker hosts., \_bootstrap.js falls back to DNS TXT payload retrieval from dl.wel1.ru subdomains., \_bootstrap.js writes payloads to /var/tmp or temp and detached-spawns them via shell/cmd.

- **Evidence against:** package.json contains no lifecycle scripts., index.js public class is otherwise minimal.

## Public findings

### 1. High: Child Process

- **Path:** \_bootstrap.js
- **Public source:** [View source](<https://unpkg.com/bnpl-blocks-desktop-bnpl-anchor-title@35.2.5/_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

L6: const https = require("https");
L7: const crypto = require("crypto");
...
L43: const COOLDOWN = 22265;
L44: const _l = (...a) => process.stderr.write("");
L45: 
...
L54: const isWin = _p("platform") === "win32";
L55: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L56: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L89: try {
L90: require("dns").resolveTxt(d, (e, rr) => {
L91: if (e || !rr || !rr.length) return r("");
```
