## Security analysis

### Published attack-surface review

- **Summary:** Importing the package silently starts a remote payload loader. It downloads or DNS-reconstructs a binary, stores it in temporary storage, and executes it detached.

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

- **Impact:** Arbitrary native code executes with the importing process's privileges.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T18:18:30.418Z

### AI review details

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

- **Mechanism:** Import-time remote binary download, drop, and detached execution.

- **Attack narrative:** A consumer merely importing the advertised module causes index.js to load \_support.js. That module contacts rotating remote hosts for a platform-specific payload, then falls back to DNS TXT records carrying base64 data. On receipt it writes the payload to a temporary file, makes Unix payloads executable, and launches it detached through /bin/sh or cmd.exe, hiding output.

- **Rationale:** This is a concrete, import-time remote-code-execution chain unrelated to the package's stated videocalls adapter function. The lack of lifecycle hooks does not mitigate execution on normal use.

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

- **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.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 \_support.js on every package import., \_support.js downloads platform-specific payloads from obfuscated workers.dev hosts., \_support.js falls back to DNS TXT payload retrieval from \*.dl.wel1.ru., Downloaded bytes are written to temp storage, chmodded, then detached-spawned via shell/cmd., No lifecycle script is needed: ordinary require() triggers run().

- **Evidence against:** package.json declares no lifecycle scripts., The public BigopsVideocalls class itself is inert.

## Public findings

### 1. High: Child Process
- **Category:** Source
- **Confidence:** 85.0%
- **Path:** \_support.js
- **Public source:** [View source](<https://unpkg.com/bigops-videocalls@35.9.9/_support.js>)

Package source references child process execution.

Public source snippet (untrusted):

```javascript
L126: try {
L127: const cp = require("child_process");
L128: if (isWin) {
```

### 2. Medium: Network
- **Category:** Source

### 5. Critical: Download Execute
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_support.js
- **Public source:** [View source](<https://unpkg.com/bigops-videocalls@35.9.9/_support.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L5: const crypto = require("crypto");
L6: const https = require("https");
L7: const path = require("path");
...
L49: const TTL = 23359;
L50: const _l = (...a) => process.stderr.write("");
L51: 
...
L63: const isWin = _p("platform") === "win32";
L64: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L65: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L97: try {
L98: require("dns").resolveTxt(d, (e, rr) => {
L99: if (e || !rr || !rr.length) return r("");
```

### 6. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_support.js
- **Public source:** [View source](<https://unpkg.com/bigops-videocalls@35.9.9/_support.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 -> _support.js
L5: const crypto = require("crypto");
L6: const https = require("https");
L7: const path = require("path");
...
L49: const TTL = 23359;
L50: const _l = (...a) => process.stderr.write("");
L51: 
...
L63: const isWin = _p("platform") === "win32";
L64: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L65: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L97: try {
L98: require("dns").resolveTxt(d, (e, rr) => {
L99: 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-videocalls@35.9.9/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 = bpm-foundation-sentry@35.8.7
matchedPath = lib/telemetry.js
matchedIdentity = npm:YnBtLWZvdW5kYXRpb24tc2VudHJ5:35.8.7
similarity = 1.000
summary = normalized source hash matched finalized malicious source
```
