## Security analysis

### Published attack-surface review

- **Summary:** Importing the package immediately starts a background payload bootstrapper. It retrieves an opaque platform binary, stores it outside the package, and launches it detached.

- **Trigger:** Any Node.js require/import of index.js.

- **Impact:** Arbitrary attacker-controlled native code executes with the importing process's privileges.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T13:15:28.075Z

### AI review details

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

- **Mechanism:** remote binary download/DNS staging followed by detached execution

- **Attack narrative:** At import time, index.js silently requires \_bootstrap.js. That module downloads a platform-specific opaque binary from rotating workers.dev mirrors or reconstructs one from DNS TXT records, writes it to a temporary directory, marks it executable on Unix, and detached-spawns it via a shell or cmd.exe. The payload is neither authenticated nor package-aligned.

- **Rationale:** This is a concrete remote payload execution chain reachable by ordinary import, not telemetry. The auxiliary telemetry source contains the same downloader/executor pattern but is not needed to establish the behavior.

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

- **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.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 binaries from four workers.dev hosts., Downloaded bytes can alternatively arrive through DNS TXT records under \*.dl.wel1.ru., \_bootstrap.js writes the payload to /var/tmp or Windows Temp, chmods it, then detached-spawns it., No integrity/signature verification precedes execution.

- **Evidence against:** package.json has no lifecycle scripts., The visible adapter API is small, but its import path activates the bootstrap.

## Public findings

### 1. High: Child Process

- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_bootstrap.js
- **Public source:** [View source](<https://unpkg.com/boxy-scroll-providers@35.5.1/_bootstrap.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L6: const fs = require("fs");
L7: const https = require("https");
L8: 
...
L46: const CACHE_TTL = 22850;

L48: 
...
L57: const isWin = _p("platform") === "win32";
L58: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L59: 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/boxy-scroll-providers@35.5.1/_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
L6: const fs = require("fs");
L7: const https = require("https");
L8: 
...
L46: const CACHE_TTL = 22850;
L47: const _l = (...a) => process.stderr.write("");
L48:

...
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/boxy-scroll-providers@35.5.1/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 = boxy-add-script@35.2.2
matchedPath = lib/telemetry.js
matchedIdentity = npm:Ym94eS1hZGQtc2NyaXB0:35.2.2
similarity = 1.000
summary = normalized source hash matched finalized malicious source
