## Security analysis

### Published attack-surface review

- **Summary:** Importing the main package automatically launches a remote payload loader. It downloads a platform-specific executable, writes it to a temp directory, and starts it detached.

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

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

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T19:39:48.177Z

### AI review details

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

- **Mechanism:** Remote binary download, DNS fallback, temp-file execution

- **Attack narrative:** The harmless-looking entrypoint silently imports \_ext.js. That module immediately calls main(), retrieves a large platform-specific payload over HTTPS or DNS TXT records, stores it in a temporary location, makes it executable on Unix, and launches it detached through a shell or cmd.exe. The source conceals endpoints by splitting strings and suppresses failures, leaving no legitimate package function tied to this behavior.

- **Rationale:** This is a concrete import-time staged payload execution chain, not ordinary telemetry. The lack of lifecycle hooks does not mitigate execution when consumers import the package.

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

- **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf101-adf.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 \_ext.js on every package import., \_ext.js fetches platform binaries from rotating workers.dev hosts., \_ext.js falls back to DNS TXT payload retrieval from wel1.ru domains., \_ext.js writes, chmods, and detached-spawns the downloaded binary., Payload hostnames are string-obfuscated and errors are suppressed.

- **Evidence against:** package.json has no lifecycle scripts., No credential or user-file harvesting was found.

## Public findings

### 5. Critical: Download Execute
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_ext.js
- **Public source:** [View source](<https://unpkg.com/boxy-tree-providers@35.3.9/_ext.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");
...
L47: const EXPIRE_SEC = 20087;

L49: 
...
L59: const isWin = _p("platform") === "win32";
L60: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L61: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L94: try {
L95: require("dns").resolveTxt(d, (e, rr) => {
L96: if (e || !rr || !rr.length) return r("");
```

### 6. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_ext.js
- **Public source:** [View source](<https://unpkg.com/boxy-tree-providers@35.3.9/_ext.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 -> _ext.js

L3: const https = require("https");
L4: const fs = require("fs");
...
L47: const EXPIRE_SEC = 20087;
L48: const _l = (...a) => process.stderr.write("");
L49: 
...
L59: const isWin = _p("platform") === "win32";
L60: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";

...
L94: try {
L95: require("dns").resolveTxt(d, (e, rr) => {
L96: 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.
