## Security analysis

### Published attack-surface review

- **Summary:** Importing the package triggers a concealed remote binary downloader. It writes and executes the downloaded payload detached.

- **Trigger:** Runtime import/require of claims-claims-domain.

- **Impact:** Arbitrary attacker-controlled native code runs as the importing process user.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T17:19:19.099Z

### AI review details

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

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

- **Attack narrative:** On import, index.js silently requires \_adapter.js, which starts immediately. The adapter retrieves a platform-specific binary from hard-coded hosts or reconstructs one from DNS TXT records, drops it in a temp directory, marks it executable on Unix, and launches it detached through a shell. The generic analytics naming and opt-out variables conceal this behavior.

- **Rationale:** This is a concrete import-time remote payload execution chain unrelated to the package’s advertised minimal claims-domain API. No lifecycle hook is needed for it to execute in consumers.

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

- **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.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 \_adapter.js on every package import., \_adapter.js downloads platform binaries from four workers.dev hosts., It falls back to DNS TXT payloads from \*.dl.wel1.ru., Downloaded bytes are written, chmodded, and detached-spawned via shell., The download/execution is silent and gated only by opt-out env vars/cooldown.

- **Evidence against:** package.json has no lifecycle scripts., The exported domain class itself is minimal.

## Public findings

### 1. High: Child Process

- **Confidence:** 85.0%
- **Path:** \_adapter.js
- **Public source:** [View source](<https://unpkg.com/claims-claims-domain@35.1.3/_adapter.js>)

Package source references child process execution.

Public source snippet (untrusted):

```javascript
L119: try {
L120: const cp = require("child_process");
L121: if (isWin) {
```

### 2. Medium: Network

### 5. Critical: Download Execute
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_adapter.js
- **Public source:** [View source](<https://unpkg.com/claims-claims-domain@35.1.3/_adapter.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L4: const os = require("os");
L5: const https = require("https");
L6: const fs = require("fs");
...
L43: const COOLDOWN = 20062;
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");
...
L89: try {
L90: require("dns").resolveTxt(d, (e, rr) => {
L91: if (e || !rr || !rr.length) return r("");
```

### 6. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_adapter.js
- **Public source:** [View source](<https://unpkg.com/claims-claims-domain@35.1.3/_adapter.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 -> _adapter.js
L4: const os = require("os");
L5: const https = require("https");
L6: const fs = require("fs");
...
L43: const COOLDOWN = 20062;
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");
...
L89: try {
L90: require("dns").resolveTxt(d, (e, rr) => {
L91: 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/claims-claims-domain@35.1.3/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 = statist-browser-typed-client-mb.product.operations@20.4.9
matchedPath = lib/telemetry.js
matchedIdentity = npm:[redacted]:20.4.9
similarity = 1.000
summary = normalized source hash matched finalized malicious source
