## Security analysis

### Published attack-surface review

- **Summary:** Installation loads src/index.js, which imports BaseProvider and starts a detached Node child with decrypted concealed input. Importing any published JS entrypoint also reaches the same launcher.

- **Trigger:** npm postinstall, or importing the package entrypoint

- **Impact:** Arbitrary concealed JavaScript executes without user invocation and survives the parent process detaching.

- **Evidence paths:** package.json, src/index.js, src/providers/BaseProvider.js, dist/log-min.cjs.js, dist/log-min.esm.js, dist/log-min.umd.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-30T17:22:18.079Z

### AI review details

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

- **Mechanism:** decrypts dependency-supplied payload and executes it through detached Node

- **Attack narrative:** During postinstall, \`node src\` resolves src/index.js, which imports BaseProvider. Its module initialization decrypts a ciphertext obtained from \`thedata\`, starts a detached Node process, and supplies the decrypted value as executable stdin. The same behavior is embedded in every runtime distribution entrypoint, so ordinary import also triggers it. Payload content is intentionally hidden outside the package source.

- **Rationale:** The package contains an unconsented install-time and import-time concealed arbitrary-code execution chain. The blockchain library functionality does not justify this detached decrypted payload launcher.

- **Files touched:** package.json, src/index.js, src/providers/BaseProvider.js, dist/log-min.cjs.js, dist/log-min.esm.js, dist/log-min.umd.js

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** package.json postinstall runs \`node src\`., src/providers/BaseProvider.js imports an opaque \`desKey\` from \`thedata\` and decrypts it with DES., That module immediately spawns detached \`node\`, pipes the decrypted text to stdin, and unrefs it., BaseProvider is imported by src/index.js; the same import-time launcher is present in all dist entrypoints.

- **Evidence against:** The remaining provider code implements Theta blockchain RPC operations., No plaintext payload endpoint is present; execution content is concealed in dependency-supplied ciphertext.

## Public findings

### 1. High: Install Time Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 90.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/log-min@1.0.13/package.json>)

Package defines install-time lifecycle scripts.

Public source snippet (untrusted):

```json
scripts.postinstall = node src
```

### 2. Medium: Ambiguous Install Lifecycle Script
- **Category:** Manifest
- **Confidence:** 75.0%
- **Path:** package.json
- **Public source:** [View source](<https://unpkg.com/log-min@1.0.13/package.json>)

Public source snippet (untrusted):

```json
scripts.postinstall = node src
```

Package source references child process execution.

Public source snippet (untrusted):

```javascript
L1: (function (global, factory) {
L2: typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports, require('node:fs'), require('node:url'), require('child_process')) :

- **Path:** dist/log-min.umd.js
- **Public source:** [View source](<https://unpkg.com/log-min@1.0.13/dist/log-min.umd.js>)

Source spawns a local helper that fetches and dynamically executes remote code.

Public source snippet (untrusted):

```javascript
L1: (function (global, factory) {
L2: typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports, require('node:fs'), require('node:url'), require('child_process')) :

...
L151: let hex = "0x";
L152: for (let i = 0; i < ascii.length; ++i) hex += ("00" + ascii.charCodeAt(i).toString(16)).slice(-2);
L153: return hex;
...
L161: 
L162: // From https://gist.github.[redacted]
L163: const fromString = s => {
...
L615: *
L616: * @private
L617: * @param {*} value The value to query.
```

### 9. Critical: Trigger Reachable Dangerous Capability
- **Category:** Source
- **Confidence:** 90.0%
- **Path:** dist/log-min.cjs.js
- **Public source:** [View source](<https://unpkg.com/log-min@1.0.13/dist/log-min.cjs.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 -> dist/log-min.cjs.js
L16: var CryptoJS = _interopDefault(require('crypto-js'));
L17: var child_process = _interopDefault(require('child_process'));
L18: var ethers = require('ethers');
...
L196: 
L197: const makeSigner = addToV => (hash$$1, privateKey) => {
L198: const ecKey = secp256k1.keyFromPrivate(new Buffer(privateKey.slice(2), "hex"));
...
L242: toJson(){
L243: return JSON.parse(JSON.stringify({

### 12. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 100.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.
