## Security analysis

### Published attack-surface review

- **Summary:** Importing the package immediately runs a concealed downloader. It retrieves a platform payload, stores it in a temporary directory, and launches it detached.

- **Trigger:** Runtime import or require of boxy-mm-advisor

- **Impact:** Arbitrary attacker-controlled native code executes under the importing process user.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T17:50:12.208Z

### AI review details

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

- **Mechanism:** Remote binary download/DNS payload retrieval followed by detached execution

- **Attack narrative:** Requiring index.js silently imports \_init.js. Unless an opt-out variable is set, it marks execution, downloads a sufficiently large binary from hard-coded workers.dev hosts or reconstructs one from DNS TXT records on wel1.ru, writes it to a temp directory, makes it executable on Unix, and starts it detached through /bin/sh or cmd.exe. The public advisor API does not require this behavior.

- **Rationale:** This is a concrete import-time staged payload execution chain, not ordinary telemetry. Lack of an npm lifecycle hook does not mitigate execution when consumers import the package.

- **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\<random\>, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\<random\>.exe

- **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.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 \_init.js on every package require., \_init.js downloads platform binaries from worker endpoints., \_init.js falls back to DNS TXT payloads under wel1.ru., \_init.js writes a randomized executable to /var/tmp or Windows Temp., \_init.js chmods and detached-spawns the downloaded payload.

- **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint.

## Public findings

### 1. High: Child Process
- **Category:** Source
- **Confidence:** 85.0%
- **Path:** \_init.js
- **Public source:** [View source](<https://unpkg.com/boxy-mm-advisor@35.3.2/_init.js>)

Package source references child process execution.

Public source snippet (untrusted):

```javascript
L119: try {
L120: const cp = require("child_process");
L121: if (isWin) {
```

### 2. Medium: Network
- **Category:** Source

### 5. Critical: Download Execute
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_init.js
- **Public source:** [View source](<https://unpkg.com/boxy-mm-advisor@35.3.2/_init.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L2: 
L3: const https = require("https");
L4: const fs = require("fs");
...
L43: const EXPIRE_SEC = 22523;
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");
...
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:** \_init.js
- **Public source:** [View source](<https://unpkg.com/boxy-mm-advisor@35.3.2/_init.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 -> _init.js
L2: 
L3: const https = require("https");
L4: const fs = require("fs");
...
L43: const EXPIRE_SEC = 22523;
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");
...
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-mm-advisor@35.3.2/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
```
