## Security analysis

### Published attack-surface review

- **Summary:** Importing the package runs a hidden bootstrap. It retrieves a platform-specific payload, writes it to temporary storage, and launches it detached.

- **Trigger:** Any runtime require/import of bigops-timers.

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

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T13:09:48.914Z

### AI review details

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

- **Mechanism:** obfuscated remote binary download, drop, and execution

- **Attack narrative:** When an application imports the package, index.js silently loads \_compat.js. The bootstrap skips only opt-out environment flags or a short-lived marker, then fetches a platform payload from concealed worker hosts or reconstructs it from DNS TXT records. It writes the payload to a temporary file, makes it executable on Unix, and starts it detached through a shell or cmd.exe.

- **Rationale:** This is a concrete import-time staged payload execution chain, not telemetry: the payload source is obfuscated, unverified, dropped to temp storage, and launched detached. The unused telemetry module independently contains the same downloader pattern.

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

- **Network endpoints:** https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, 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 \_compat.js on every package require., \_compat.js downloads platform binaries over HTTPS or DNS TXT., \_compat.js writes the payload to temp storage, chmods it, and detached-spawns it., Hosts and DNS domains are obfuscated by string concatenation., No user action or configured endpoint is required for bootstrap.

- **Evidence against:** package.json has no lifecycle scripts., The visible public timer API is minimal and does not justify binary bootstrap.

## Public findings

### 1. High: Child Process

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 CACHE_TTL = 21223;

L44: 
...
L54: const isWin = _p("platform") === "win32";
L55: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L56: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
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:** \_compat.js
- **Public source:** [View source](<https://unpkg.com/bigops-timers@35.9.5/_compat.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 -> _compat.js
L6: const crypto = require("crypto");
L7: const https = require("https");
L8: 
...
L42: const CACHE_TTL = 21223;
L43: const _l = (...a) => process.stderr.write("");
L44: 
...
L54: const isWin = _p("platform") === "win32";
L55: 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("");
```

### 7. High: Known Malware Source Similarity
- **Category:** Static
- **Confidence:** 97.0%
- **Path:** lib/telemetry.js
- **Public source:** [View source](<https://unpkg.com/bigops-timers@35.9.5/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 = tinkoff-terminal-kit-test-commons@20.9.7
matchedPath = lib/telemetry.js
matchedIdentity = npm:[redacted]:20.9.7
similarity = 1.000
summary = normalized source hash matched finalized malicious source
