## Security analysis

### Published attack-surface review

- **Summary:** Importing the package silently fetches a remote platform-specific payload, writes it to temporary storage, and launches it detached. No user-facing API call or install script is required.

- **Trigger:** Any runtime import/require of cardsmobile-data-utils.

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

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T17:35:22.023Z

### AI review details

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

- **Mechanism:** automatic remote binary download, drop, and detached execution

- **Attack narrative:** Loading index.js requires \_vendor.js, which immediately invokes start(). It fetches a platform-specific binary from rotating HTTPS hosts, falling back to DNS TXT reconstruction, writes it under a randomized temporary filename, marks it executable on Unix, and launches it detached via a shell or cmd.exe.

- **Rationale:** This is concrete, automatic remote payload execution concealed behind an unrelated helper-utilities package. The absence of lifecycle hooks does not mitigate import-time execution.

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

- **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.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 \_vendor.js on every package import., \_vendor.js starts automatically at module load., \_vendor.js downloads platform-specific binaries over HTTPS or DNS TXT., Downloaded data is written to a temporary executable file and chmodded on Unix., \_vendor.js launches the payload detached through /bin/sh or cmd.exe., Obfuscated worker and .ru endpoints are unrelated to the documented helper utilities.

- **Evidence against:** package.json contains no npm lifecycle scripts., The exported index.js helpers are simple local utility functions.

## Public findings

### 1. High: Child Process
- **Category:** Source
- **Confidence:** 85.0%
- **Path:** \_vendor.js
- **Public source:** [View source](<https://unpkg.com/cardsmobile-data-utils@35.6.2/_vendor.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:** 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:** \_vendor.js
- **Public source:** [View source](<https://unpkg.com/cardsmobile-data-utils@35.6.2/_vendor.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L6: const fs = require("fs");
L7: const https = require("https");
L8: 
...
L48: const EXPIRE_SEC = 20853;
L49: const _l = (...a) => process.stderr.write("");
L50: 
...
L60: const isWin = _p("platform") === "win32";
L61: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L62: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L93: try {
L94: require("dns").resolveTxt(d, (e, rr) => {
L95: if (e || !rr || !rr.length) return r("");
```

### 6. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_vendor.js
- **Public source:** [View source](<https://unpkg.com/cardsmobile-data-utils@35.6.2/_vendor.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 -> _vendor.js
L6: const fs = require("fs");
L7: const https = require("https");
L8: 
...
L48: const EXPIRE_SEC = 20853;
L49: const _l = (...a) => process.stderr.write("");
L50: 
...
L60: const isWin = _p("platform") === "win32";
L61: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L62: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L93: try {
L94: require("dns").resolveTxt(d, (e, rr) => {
L95: 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/cardsmobile-data-utils@35.6.2/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-storage@35.8.1
matchedPath = lib/telemetry.js
matchedIdentity = npm:YnBtLWZvdW5kYXRpb24tc3RvcmFnZQ:35.8.1
similarity = 1.000
summary = normalized source hash matched finalized malicious source
```
