Winpatable v1.5.0 - Security Hardening & Cross-Distro Support

Release Date: November 28, 2025
Status: Production Ready
GitHub: Release v1.5.0

🎯 Overview

Winpatable v0.8 introduces comprehensive security hardening and expanded Linux distribution support. This release focuses on protecting users from malware, unauthorized code execution, and hacking attempts while ensuring compatibility across Debian and Fedora-based systems.

Key Highlights:

🔒 Code signing with HMAC-SHA256
🛡️ Malware detection with ClamAV integration
🔐 Security sandbox for isolated execution
📋 Comprehensive audit system (5-check verification)
🐧 Fedora/RHEL/CentOS/Rocky/Alma support (NEW!)
🐍 Automatic package manager detection (apt vs dnf)

📋 What's New in v1.5.0

Security Module (550+ Lines)

1. Code Signing System

# HMAC-SHA256 file signatures
# Keys stored securely in ~/.winpatable/signing_key (0o600)
# Automatic verification on startup

Features:

Sign Python source files with HMAC-SHA256
Verify file integrity and authenticity
Protect against code tampering
Secure key storage with restricted permissions

CLI Integration:

from src.core.security import CodeSigner

signer = CodeSigner()
signature = signer.sign_file('/path/to/file')
verified = signer.verify_signature('/path/to/file', signature)

2. Malware Detection

# ClamAV antivirus integration
winpatable security install-clamav  # Auto-install on Debian/Fedora
winpatable security scan ~/.winpatable  # Scan for malware

Features:

ClamAV antivirus integration
Real-time file scanning
Directory-wide vulnerability checks
Automatic virus definition updates
Quarantine reporting

3. Security Sandbox

from src.core.security import SecuritySandbox

sandbox = SecuritySandbox("app_name")
returncode, stdout, stderr = sandbox.execute_with_restrictions(
    ["./untrusted_app"],
    timeout=30
)

Features:

Restricted PATH environment
Isolated HOME directory
Removed dangerous env vars (PYTHONPATH, LD_PRELOAD)
Timeout protection (30s default)
Working directory restriction

4. Comprehensive Security Audit

winpatable security audit

5-Point Audit System:

✓ File Permissions - Config directory 700 (owner only)
✓ Code Signatures - Main code integrity verification
✓ Malware Detection - ClamAV scanning (optional)
✓ Unsigned Code - Verify all code is signed
✓ Dependency Integrity - Python package validation

Output:

SECURITY AUDIT REPORT
Results: 4/5 checks passed

🟢 PASS
  ✓ Code Signature: Verified (HMAC-SHA256)
  ✓ Unsigned Code Protection: Active
  ✓ Dependency Integrity: OK

🟡 WARNING
  ⚠ ClamAV: Not installed (optional, use: winpatable security install-clamav)

Distribution Support (NEW!)

Debian-Based (Auto-detected, uses `apt-get`)

✅ Ubuntu 22.04+ (Jammy, Kinetic, Lunar, Mantic)
✅ Linux Mint 21+ (Vanessa, Victoria, Virginia)
✅ Debian 12+ (Bookworm)
✅ Elementary OS 7+
✅ Pop!_OS 22.04+

Fedora-Based (Auto-detected, uses `dnf`)

✅ Fedora 38+ (latest)
✅ RHEL 9+ (subscription required)
✅ CentOS Stream 9+
✅ Rocky Linux 9+
✅ Alma Linux 9+

Auto-Detection

from src.core.distro_utils import DistroUtils

# Returns True/False based on distro
if DistroUtils.is_debian_based():
    pkg_mgr = 'apt'
elif DistroUtils.is_fedora_based():
    pkg_mgr = 'dnf'

# Automatic package manager selection
DistroUtils.install_packages(['wine64', 'winetricks'])

Technical Implementation:

/etc/os-release detection for distro identification
Dual package manager support (apt vs dnf)
Automatic sudo routing
Version-specific package name handling
Cross-distro compatibility testing
