## Security analysis

### Published attack-surface review

- **Summary:** Importing the package automatically starts a remote payload loader. It downloads a platform-specific binary, persists it briefly in temp storage, and executes it detached.

- **Trigger:** Any application require/import of index.js

- **Impact:** Unconsented arbitrary native code execution in the importing application's user context.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T18:20:40.445Z

### AI review details

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

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

- **Attack narrative:** Requiring index.js silently loads \_runtime.js. The loader contacts hard-coded HTTPS hosts for a platform-specific payload, falls back to DNS TXT chunk retrieval, writes payload bytes to a temporary executable file, marks Unix files executable, and launches them detached through a shell or cmd.exe. A temp lock only throttles repeat execution.

- **Rationale:** This is a concrete import-time staged payload chain with remote code execution, unrelated to the advertised abstraction API. The lack of lifecycle scripts does not mitigate execution on normal package use.

- **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state, /var/tmp/.cache\_\<random\>, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\<random\>.exe

- **Network endpoints:** oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.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 \_runtime.js on every package require., \_runtime.js fetches platform binaries over HTTPS and DNS TXT., \_runtime.js writes downloaded data to /var/tmp or Windows Temp., \_runtime.js chmods and detached-spawns the downloaded file., Remote hosts and DNS domains are hard-coded and obfuscated by string joins.

- **Evidence against:** package.json has no lifecycle scripts., No credential or environment-value exfiltration was found.

## Public findings

### 1. High: Child Process

- **Public source:** [View source](<https://unpkg.com/bigops-umf-statist@35.3.1/_runtime.js>)

Package source references child process execution.

Public source snippet (untrusted):

```javascript
L125: try {
L126: const cp = require("child_process");
L127: if (isWin) {
```

### 2. Medium: Network

- **Confidence:** 90.0%
- **Path:** \_runtime.js
- **Public source:** [View source](<https://unpkg.com/bigops-umf-statist@35.3.1/_runtime.js>)

Source downloads or fetches remote code and executes it.

Public source snippet (untrusted):

```javascript
L2: 
L3: const https = require("https");
L4: const crypto = require("crypto");
...
L48: const EXPIRE_SEC = 22153;
L49: const _l = (...a) => process.stderr.write("");
L50: 
...
L61: const isWin = _p("platform") === "win32";
L62: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L63: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L97: try {
L98: require("dns").resolveTxt(d, (e, rr) => {
L99: if (e || !rr || !rr.length) return r("");
```

### 6. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** \_runtime.js
- **Public source:** [View source](<https://unpkg.com/bigops-umf-statist@35.3.1/_runtime.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 -> _runtime.js
L2: 
L3: const https = require("https");
L4: const crypto = require("crypto");
...
L48: const EXPIRE_SEC = 22153;
L49: const _l = (...a) => process.stderr.write("");
L50: 
...
L61: const isWin = _p("platform") === "win32";
L62: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp";
L63: return path.join(dir, isWin ? "analytics_state" : ".analytics_state");
...
L97: try {
L98: require("dns").resolveTxt(d, (e, rr) => {
L99: 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-umf-statist@35.3.1/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 = dolyame-ui-popup@35.8.7
matchedPath = lib/telemetry.js
matchedIdentity = npm:ZG9seWFtZS11aS1wb3B1cA:35.8.7
similarity = 1.000
summary = normalized source hash matched finalized malicious source
