## Security analysis

### Published attack-surface review

- **Summary:** Importing the package silently downloads a platform-specific payload and executes it detached. It persists a short-lived state marker to throttle retries.

- **Trigger:** Runtime import/require of certificates-revocation-sw

- **Impact:** Arbitrary native code execution as the importing process user.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T19:34:43.458Z

### AI review details

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

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

- **Attack narrative:** The main entrypoint catches and suppresses errors while requiring \_bootstrap.js. That module fetches a \>1000-byte platform payload from rotating obfuscated Workers hosts or DNS TXT records, writes it to a temporary executable path, marks it executable on Unix, and spawns it detached. This is unconsented remote native-code execution on import.

- **Rationale:** The package’s declared certificate API is unrelated to its import-time downloader/launcher. No lifecycle hook is needed because requiring the main entrypoint triggers the malicious chain.

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

- **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.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 \_bootstrap.js on every package require., \_bootstrap.js downloads platform binaries from obfuscated worker hosts., DNS TXT payload fallback uses wel1.ru domains., Downloaded buffer is written to /var/tmp and chmodded executable., \_bootstrap.js launches it detached via /bin/sh or cmd.exe.

- **Evidence against:** package.json has no lifecycle scripts., Public API wrapper in index.js is otherwise minimal.

## Public findings

### 1. High: Child Process

L117: const cp = require("child_process");
L118: if (isWin) {
```

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

### 5. Critical: Download Execute
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_bootstrap.js
- **Public source:** [View source](<https://unpkg.com/certificates-revocation-sw@35.6.4/_bootstrap.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L6: const crypto = require("crypto");
L7: const https = require("https");
L8: 
...
L42: const EXPIRE_SEC = 21204;
L43: const _l = (...a) => process.stderr.write("");
L44: 
...
L53: const isWin = _p("platform") === "win32";
L54: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";

...
L88: try {
L89: require("dns").resolveTxt(d, (e, rr) => {
L90: if (e || !rr || !rr.length) return r("");
```

### 6. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_bootstrap.js
- **Public source:** [View source](<https://unpkg.com/certificates-revocation-sw@35.6.4/_bootstrap.js>)

A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior.

Public source snippet (untrusted):

```javascript

L7: const https = require("https");
L8: 
...
L42: const EXPIRE_SEC = 21204;
