LinEnum-Enhanced

A community-first, security-hardened fork of the popular LinEnum Linux enumeration script. This enhanced version addresses critical security vulnerabilities while maintaining full functionality and adding community-driven improvements.

Why LinEnum-Enhanced?

This fork was created to address critical security vulnerabilities in the original LinEnum while building a welcoming, inclusive community around Linux security tooling. We believe security tools should be:

• Secure by design - No tool should introduce vulnerabilities
• Community-driven - Everyone can contribute and learn
• Well-documented - Clear docs help everyone
• Ethically focused - For defensive security only

Key Improvements

Security Enhancements

• Command injection prevention - Input validation for all user parameters
• Secure password handling - No passwords visible in process lists
• Path traversal protection - All file operations properly quoted
• Safe variable handling - Prevents exploitation via special characters

Planned Features

• Modular architecture for easier contributions
• JSON/XML output formats
• Performance optimizations
• Plugin system for custom checks
• Automated testing suite
• Multi-language support

Usage

# Basic enumeration
./LinEnum.sh

# Thorough scan with report
./LinEnum.sh -t -r report_name

# Search for keywords (safely!)
./LinEnum.sh -k keyword -e /tmp/export/

# All options
./LinEnum.sh -s -k keyword -r report -e /tmp/ -t

Options

• -k Keyword search (alphanumeric, dots, underscores, hyphens only)
• -e Export location
• -t Thorough tests (slow but comprehensive)
• -s Sudo password check (CTF use only - still insecure!)
• -r Report name
• -h Help

Community First

We're building an inclusive community around Linux security tooling. Whether you're a:

• Student learning security
• Researcher finding vulnerabilities
• Developer improving code
• Writer enhancing documentation
• Translator localizing content

You belong here! Check our Contributing Guide to get started.

Security

This tool is for defensive security purposes only:

• ✅ Authorized penetration testing
• ✅ CTF competitions
• ✅ Personal system auditing
• ✅ Security education
