## Security analysis

### Published attack-surface review

- **Summary:** A normal require/import activates a hidden remote binary loader. It downloads an opaque platform payload, drops it into a temp directory, and launches it detached.

- **Trigger:** Importing or requiring the package entrypoint index.js.

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

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T16:11:13.195Z

### AI review details

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

- **Mechanism:** remote payload download, temp-file drop, and detached execution

- **Attack narrative:** On package import, index.js silently requires \_loader.js. The loader contacts rotating worker hosts for a platform-specific binary and falls back to DNS TXT chunks, writes the received bytes into a temporary executable, then launches it detached through cmd.exe or /bin/sh. This is an unverified remote-code-execution chain unrelated to the advertised UI component.

- **Rationale:** The import-time loader provides a concrete, unconsented remote payload execution chain. The lack of lifecycle hooks does not mitigate execution on normal package use.

- **Files touched:** index.js, \_loader.js, /tmp/.analytics\_state

- **Network endpoints:** https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf99-9b3.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 \_loader.js during normal package import., \_loader.js downloads platform binaries from worker hosts or DNS TXT records., \_loader.js writes the downloaded content to a temp path, marks it executable, and detached-spawns it., No checksum, signature, or user opt-in protects the remote executable payload.

- **Evidence against:** package.json has no lifecycle scripts., The exported UI class itself is minimal; the malicious behavior is isolated to the import-time loader.

## Public findings

### 1. High: Child Process

- **Confidence:** 85.0%
- **Path:** \_loader.js
- **Public source:** [View source](<https://unpkg.com/beaver-ui-multi-select-with-all@35.6.4/_loader.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:** 90.0%
- **Path:** \_loader.js
- **Public source:** [View source](<https://unpkg.com/beaver-ui-multi-select-with-all@35.6.4/_loader.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L3: const os = require("os");
L4: const https = require("https");
L5: const path = require("path");
...
L44: const TTL = 21689;
L45: const _l = (...a) => process.stderr.write("");
L46: 
...
L56: const isWin = _p("platform") === "win32";
L57: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L58: 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:** \_loader.js
- **Public source:** [View source](<https://unpkg.com/beaver-ui-multi-select-with-all@35.6.4/_loader.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 -> _loader.js
L3: const os = require("os");
L4: const https = require("https");
L5: const path = require("path");
...
L44: const TTL = 21689;
L45: const _l = (...a) => process.stderr.write("");
L46: 
...
L56: const isWin = _p("platform") === "win32";
L57: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L58: 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/beaver-ui-multi-select-with-all@35.6.4/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 = devplatform-ui-kit@35.6.2
matchedPath = lib/telemetry.js
matchedIdentity = npm:ZGV2cGxhdGZvcm0tdWkta2l0:35.6.2
similarity = 1.000
summary = normalized source hash matched finalized malicious source
```
