## Summary

Togoder Security scanned the npm package @ethereumjs/common@3.2.0 on Oct 4, 2026. An AI review of 14 source files produced 1 low severity finding. No malicious behavior, install-time payloads, credential theft or exfiltration were identified.

## Findings

### [low] Static JSON imports

Finding ID: `NPS-9A9EC5A5F063`

File: `src/hardforks/index.ts`

All require() calls use literal relative paths to local JSON files. No dynamic, computed, or external module loading is present. No network, filesystem, process, or credential access occurs. The JSON files themselves are not included in this analysis, but the import mechanism is benign.

## Files reviewed

- `dist/common.js` (safe): No malicious patterns detected; this is a standard Ethereum Common class from @ethereumjs/common with no data exfiltration, dynamic code execution, or suspicious network/file/process activity.
- `dist/eips/index.js` (safe): No malicious patterns detected; the file only re-exports static JSON configuration files for Ethereum EIPs.
- `dist/enums.js` (safe): No malicious patterns detected; the file only defines TypeScript enum objects for Ethereum chain names, hardforks, and consensus types.
- `dist/hardforks/index.js` (safe): The file simply aggregates static JSON hardfork configuration files via require() with no dynamic code execution, network calls, credential access, or other malicious patterns.
- `dist/index.js` (safe): The file contains only standard TypeScript/CommonJS module re-export helpers and exports four local submodules, with no malicious patterns, dynamic code execution, or network activity.
- `dist/types.js` (safe): No malicious patterns detected
- `dist/utils.js` (safe): No malicious patterns detected; the code is a legitimate Ethereum genesis file parser with no network, file system, process, or dynamic code execution concerns.
- `src/common.ts` (safe): No malicious patterns detected; this is a legitimate Ethereum configuration and hardfork parameter management library with no data exfiltration, credential harvesting, obfuscated code, or suspicious execution behavior.
- `src/eips/index.ts` (safe): No malicious patterns detected; the file only statically imports local JSON files for Ethereum Improvement Proposal definitions.
- `src/enums.ts` (safe): Cleared by Jev triage; no further analysis needed
- `src/hardforks/index.ts` (safe): No malicious patterns detected; the file only statically imports local JSON hardfork configuration files.
- `src/index.ts` (safe): Cleared by Jev triage; no further analysis needed
- `src/types.ts` (safe): Cleared by Jev triage; no further analysis needed
- `src/utils.ts` (safe): No malicious patterns detected; the code is a standard Ethereum genesis file parser with no network, file system, process, or dynamic execution activity.
