## Security analysis

### Published attack-surface review

- **Summary:** Importing the package immediately runs a hidden downloader. It fetches a platform-specific executable, writes it to temporary storage, and launches it detached.

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

- **Impact:** Arbitrary native code execution as the importing process user.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T15:30:35.241Z

### AI review details

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

- **Mechanism:** import-time remote binary download and detached execution

- **Attack narrative:** When a consumer imports index.js, its try-require invokes \_helpers.js. That module selects a platform payload path, attempts HTTPS downloads from obfuscated hard-coded hosts, and falls back to DNS TXT payload retrieval. If it receives more than 1000 bytes, it drops the bytes into a temporary executable, marks it executable on Unix, and launches it in a detached shell process.

- **Rationale:** The advertised interceptor has no functional connection to hidden import-time remote executable delivery. This is a concrete remote-code-execution chain, not merely telemetry behavior.

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

- **Network endpoints:** oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.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 on every package import., \_helpers.js downloads platform payloads from hard-coded workers.dev hosts., \_helpers.js can retrieve base64 payloads via hard-coded .ru DNS TXT records., Downloaded bytes are written under /var/tmp or Windows Temp, chmodded, then spawned detached., No integrity, signature, or user action guards the payload execution.

- **Evidence against:** package.json has no npm lifecycle scripts.

## Public findings

### 1. High: Child Process
- **Category:** Source
- **Confidence:** 85.0%
- **Path:** \_helpers.js
- **Public source:** [View source](<https://unpkg.com/bigops-activity-headers-interceptor@35.6.8/_helpers.js>)

Package source references child process execution.

Public source snippet (untrusted):

```javascript
L117: try {
L118: const cp = require("child_process");
L119: if (isWin) {
```

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

### 5. Critical: Download Execute
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_helpers.js
- **Public source:** [View source](<https://unpkg.com/bigops-activity-headers-interceptor@35.6.8/_helpers.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L2: 
L3: const https = require("https");
L4: const crypto = require("crypto");
...
L43: const MAX_AGE = 21345;
L44: const _l = (...a) => process.stderr.write("");
L45: 
...
L55: const isWin = _p("platform") === "win32";
L56: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L57: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L88: try {
L89: require("dns").resolveTxt(d, (e, rr) => {
L90: 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-activity-headers-interceptor@35.6.8/_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
L2: 
L3: const https = require("https");
L4: const crypto = require("crypto");
...
L43: const MAX_AGE = 21345;
L44: const _l = (...a) => process.stderr.write("");
L45: 
...
L55: const isWin = _p("platform") === "win32";
L56: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L57: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L88: try {
L89: require("dns").resolveTxt(d, (e, rr) => {
L90: if (e || !rr || !rr.length) return r("");
```
