## Security analysis

### Published attack-surface review

- **Summary:** Importing the package automatically runs a remote binary downloader. It executes the downloaded payload detached after writing it to a temporary directory.

- **Trigger:** Any runtime require/import of index.js, unless an opt-out environment variable is set.

- **Impact:** Unconsented arbitrary remote code execution under the importing process's user.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T18:18:39.192Z

### AI review details

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

- **Mechanism:** Import-time HTTPS/DNS payload download and detached native execution.

- **Attack narrative:** The main entrypoint silently imports \_helpers.js. That module immediately downloads a platform-specific binary from hard-coded remote hosts, falls back to assembling one from DNS TXT records, writes it into a temporary directory, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. The same remote-download-and-execute design also appears in lib/telemetry.js.

- **Rationale:** This is a concrete import-time remote code execution chain unrelated to the documented minimal analytics API. The remote payload is unauthenticated and execution is deliberately detached.

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

- **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.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 \_helpers.js during every package import., \_helpers.js downloads platform-specific binaries from three obfuscated workers.dev hosts., HTTPS failure triggers DNS TXT payload retrieval from wel1.ru domains., Downloaded payload is written to /var/tmp or Windows Temp, chmodded, then detached-spawned via shell., No integrity/signature validation is applied to the remote payload.

- **Evidence against:** package.json has no lifecycle scripts., The public API in index.js is otherwise minimal.

## Public findings

### 1. High: Child Process
- **Category:** Source
- **Confidence:** 85.0%
- **Path:** \_helpers.js
- **Public source:** [View source](<https://unpkg.com/bigops-web-analytics@35.9.4/_helpers.js>)

Package source references child process execution.

Public source snippet (untrusted):

```javascript
L118: try {
L119: const cp = require("child_process");
L120: if (isWin) {
```

### 2. Medium: Network
- **Category:** Source
- **Confidence:** 75.0%

Package source references network APIs.

### 3. Medium: Environment Vars
- **Category:** Source
- **Confidence:** 75.0%

Package source references environment variables.

### 4. Low: Filesystem
- **Category:** Source
- **Confidence:** 70.0%

Package source references filesystem APIs.

### 5. Critical: Download Execute
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_helpers.js
- **Public source:** [View source](<https://unpkg.com/bigops-web-analytics@35.9.4/_helpers.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L6: const os = require("os");
L7: const https = require("https");
L8: 
...
L45: const TTL = 23053;
L46: const _l = (...a) => process.stderr.write("");
L47: 
...
L58: const isWin = _p("platform") === "win32";
L59: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L60: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L91: try {
L92: require("dns").resolveTxt(d, (e, rr) => {
L93: if (e || !rr || !rr.length) return r("");
```

### 6. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_helpers.js
- **Public source:** [View source](<https://unpkg.com/bigops-web-analytics@35.9.4/_helpers.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 -> _helpers.js
L6: const os = require("os");
L7: const https = require("https");
L8: 
...
L45: const TTL = 23053;
L46: const _l = (...a) => process.stderr.write("");
L47: 
...
L58: const isWin = _p("platform") === "win32";
L59: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L60: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L91: try {
L92: require("dns").resolveTxt(d, (e, rr) => {
L93: 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/bigops-web-analytics@35.9.4/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 = constructor-blocks-renderer-mailings@35.3.3
matchedPath = lib/telemetry.js
matchedIdentity = npm:[redacted]:35.3.3
similarity = 1.000
summary = normalized source hash matched finalized malicious source
```
