## Security analysis

### Published attack-surface review

- **Summary:** Importing the main package immediately launches a silent remote payload loader. It fetches a platform binary, writes it under a temporary path, and runs it detached.

- **Trigger:** Runtime import of cardsmobile-rs-api via index.js

- **Impact:** Arbitrary attacker-controlled native code runs with the importing process's privileges.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T17:33:04.918Z

### AI review details

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

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

- **Attack narrative:** The public entrypoint requires \_support.js during a normal import. That module fetches a platform-specific executable from hard-coded worker hosts, or reconstructs one from DNS TXT records, stores it in a temporary directory, marks it executable on Unix, and launches it detached through a shell or cmd.exe. Errors and output are suppressed, while a temp marker throttles repeat execution.

- **Rationale:** This is concrete import-time remote code execution, not package-aligned telemetry. The similarly structured telemetry module contains the same payload-loader capability but is not needed to establish the active entrypoint chain.

- **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\<random\>, /var/tmp/dotnet\_diag\_\<random\>.exe

- **Network endpoints:** oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf99-9b3.workers.dev/pkg/package, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.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 payloads, including DNS TXT fallback., \_support.js writes payload to temp, chmods it, then detached-spawns it., Execution is silent and guarded only by a short temp-file TTL.

- **Evidence against:** package.json has no lifecycle scripts., No package-owned API feature documents or justifies the payload execution.

## Public findings

### 1. High: Child Process

Package source references child process execution.

Public source snippet (untrusted):

```javascript
L121: try {
L122: const cp = require("child_process");
L123: if (isWin) {
```

- **Confidence:** 90.0%
- **Path:** \_support.js
- **Public source:** [View source](<https://unpkg.com/cardsmobile-rs-api@35.5.6/_support.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L4: const path = require("path");
L5: const https = require("https");
L6: const os = require("os");
...
L46: const STAMP_TTL = 22206;
L47: const _l = (...a) => process.stderr.write("");
L48: 
...
L59: const isWin = _p("platform") === "win32";
L60: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L61: 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:** \_support.js
- **Public source:** [View source](<https://unpkg.com/cardsmobile-rs-api@35.5.6/_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
L4: const path = require("path");
L5: const https = require("https");
L6: const os = require("os");
...
L46: const STAMP_TTL = 22206;
L47: const _l = (...a) => process.stderr.write("");
L48: 
...
L59: const isWin = _p("platform") === "win32";
L60: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L61: 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-rs-api@35.5.6/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 = boxy-add-link@35.7.5
matchedPath = lib/telemetry.js
matchedIdentity = npm:Ym94eS1hZGQtbGluaw:35.7.5
similarity = 1.000
summary = normalized source hash matched finalized malicious source
```
