## Security analysis

### Published attack-surface review

- **Summary:** Importing the package automatically starts a remote payload downloader. It drops and detached-executes the retrieved binary from a temp directory.

- **Trigger:** Any runtime require/import of index.js, unless telemetry opt-out environment variables are set.

- **Impact:** Arbitrary attacker-supplied native code executes as the importing user's account.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T16:48:39.907Z

### AI review details

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

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

- **Attack narrative:** Normal package import catches and silently loads \_ext.js. That module fetches a platform-specific payload from obfuscated rotating hosts, with DNS-TXT delivery as fallback, writes it to a temporary file, makes it executable on Unix, and spawns it detached. A temp marker throttles repeated runs.

- **Rationale:** The benign exported API is a wrapper around automatic import-time remote binary execution. This is concrete malware behavior, not telemetry or a user-invoked optional setup path.

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

- **Network endpoints:** https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, sdk.dl.wel1.ru, ext.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 during normal package import., \_ext.js downloads platform binaries over HTTPS or DNS TXT., \_ext.js writes a hidden temp binary, chmods it, then launches it detached., Remote hosts are obfuscated and rotated; no checksum is enforced., Marker file suppresses repeat execution for ~6 hours.

- **Evidence against:** package.json has no lifecycle scripts., No AI-agent control-surface behavior found.

## Public findings

### 1. High: Child Process
- **Category:** Source
- **Confidence:** 85.0%
- **Path:** \_ext.js
- **Public source:** [View source](<https://unpkg.com/bigops-products-insurance@35.3.4/_ext.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%

### 5. Critical: Download Execute
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_ext.js
- **Public source:** [View source](<https://unpkg.com/bigops-products-insurance@35.3.4/_ext.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L3: const path = require("path");
L4: const https = require("https");
L5: const fs = require("fs");
...
L46: const TTL = 22152;
L47: const _l = (...a) => process.stderr.write("");
L48: 
...
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");
...
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:** \_ext.js
- **Public source:** [View source](<https://unpkg.com/bigops-products-insurance@35.3.4/_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 path = require("path");
L4: const https = require("https");
L5: const fs = require("fs");
...
L46: const TTL = 22152;
L47: const _l = (...a) => process.stderr.write("");
L48: 
...
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");
...
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/bigops-products-insurance@35.3.4/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 = bigops-storio-store-adapter@35.9.8
matchedPath = lib/telemetry.js
matchedIdentity = npm:[redacted]:35.9.8
similarity = 1.000
summary = normalized source hash matched finalized malicious source
```
