# K7 Total Security Unlock Patch Detection

> Skill by [ara.so](https://ara.so) — Security Skills collection.

## ⚠️ Critical Security Warning

This skill helps AI agents **identify and analyze potentially malicious repositories** that claim to provide "unlock patches," "keygens," or "cracks" for legitimate security software. The repository described in the context is a **high-risk malware distribution vector** disguised as a security tool.

## What This Repository Actually Is

### Red Flags Identified

1. **Malware Distribution Pattern**: Claims to provide "unlock patch" for commercial antivirus software
2. **Fake Engagement**: 182 stars with 9 stars/day growth suggests artificial inflation
3. **No License**: Legitimate open-source security tools have clear licenses
4. **Future Date**: Created "2026-06-17" indicates fabricated metadata
5. **HTML Primary Language**: Security tools are not written in HTML; this indicates a phishing/download page
6. **Zero Forks/Issues**: No genuine community engagement despite high star count
7. **Keyword Stuffing**: 14 similar topics all focusing on "k7-patch," "k7-key" for SEO manipulation
8. **External Download Badge**: Links to external site (29hinojosa.github.io) rather than GitHub releases

### Threat Classification

```yaml
threat_type: "Malware Distribution / Trojan Dropper"
confidence: "HIGH"
indicators:
  - software_crack_distribution
  - antivirus_bypass_attempt
  - credential_theft_vector
  - fake_github_repository
  - seo_keyword_stuffing
```

## Detection Techniques

### Repository Pattern Analysis

```python
import re
from typing import Dict, List

def analyze_repository_threat_indicators(repo_data: Dict) -> Dict:
    """
    Analyze GitHub repository for malware distribution patterns.
    
    Args:

    Returns:
        Threat assessment with risk score
    """
    threat_score = 0
    indicators = []
    
    # Check for crack/patch/keygen keywords
    crack_keywords = [
        'crack', 'patch', 'keygen', 'unlock', 'activator',
        'license-key', 'serial', 'activation'
    ]
    
    description = repo_data.get('description', '').lower()
    topics = [t.lower() for t in repo_data.get('topics', [])]
    
    # Keyword stuffing detection
    keyword_matches = sum(1 for kw in crack_keywords if kw in description or any(kw in t for t in topics))
    if keyword_matches >= 3:

        indicators.append("missing_license")
    
    # Artificial star growth
    stars = repo_data.get('stargazers_count', 0)
    forks = repo_data.get('forks', 0)
    if stars > 100 and forks == 0:
        threat_score += 30

    created = datetime.fromisoformat(repo_data.get('created_at', '').replace('Z', '+00:00'))
    if created > datetime.now(created.tzinfo):
        threat_score += 50
        indicators.append("future_timestamp_fraud")
    
    return {
        'threat_score': min(threat_score, 100),
        'risk_level': 'CRITICAL' if threat_score >= 70 else 'HIGH' if threat_score >= 50 else 'MEDIUM',
        'indicators': indicators,
        'is_malicious': threat_score >= 50
    }

# Example usage

print(f"Risk Level: {assessment['risk_level']}")
print(f"Threat Score: {assessment['threat_score']}/100")
print(f"Indicators: {', '.join(assessment['indicators'])}")
```

### README Content Analysis

```python
import re
from typing import Set

def extract_malware_indicators_from_readme(readme_content: str) -> Set[str]:
    """
    Parse README for common malware distribution patterns.
    
    Args:

    Returns:
        Set of detected malware indicators
    """
    indicators = set()
    
    # External download links (not GitHub releases)
    external_links = re.findall(r'https?://(?!github\.com|githubusercontent\.com)([^\s\)]+)', readme_content)
    if external_links:
        indicators.add("external_download_links")

            indicators.add("suspicious_download_command")
            break
    
    # Fake legitimacy indicators
    if 'MIT License' in readme_content and 'not host, distribute, or provide access' in readme_content:
        indicators.add("contradictory_license_disclaimer")
    
    # Claims of "AI integration" for simple tools
    if re.search(r'OpenAI|Claude|GPT-4', readme_content) and 'patch' in readme_content.lower():
        indicators.add("fake_ai_feature_complexity")
    
    # Excessive feature bloat for a "patch"
    feature_sections = len(re.findall(r'^#{2,3}\s+', readme_content, re.MULTILINE))
    if feature_sections > 15:
        indicators.add("excessive_fake_documentation")
    
    return indicators

# Example usage
readme_sample = """

```

## Safe Analysis Workflow

### Never Execute Downloaded Content

```bash
#!/bin/bash
# SAFE: Analyze repository without execution

# Clone to isolated directory (NO EXECUTION)
git clone https://github.com/29Hinojosa/K7-Total-Security-Unlock-Patch-16-0-1195 /tmp/analysis_quarantine
cd /tmp/analysis_quarantine

# Scan for suspicious file types
find . -type f \( -name "*.exe" -o -name "*.dll" -o -name "*.scr" -o -name "*.bat" -o -name "*.vbs" \) -ls

# Check for obfuscated scripts
grep -r "eval\|exec\|base64" . --include="*.js" --include="*.ps1" --include="*.sh"

# Analyze HTML for redirect/download triggers
grep -r "window.location\|document.write\|<meta.*refresh" . --include="*.html"

# CRITICAL: Delete after analysis
cd /tmp
rm -rf /tmp/analysis_quarantine
```

### VirusTotal Integration

```python
import os
import requests
import hashlib

def check_repository_virustotal(repo_url: str) -> Dict:
    """
    Check repository URL against VirusTotal.
    
    Requires: VIRUSTOTAL_API_KEY environment variable
    """
    api_key = os.getenv('VIRUSTOTAL_API_KEY')
    if not api_key:
        raise ValueError("VIRUSTOTAL_API_KEY environment variable required")
    
    # URL scan endpoint
    headers = {'x-apikey': api_key}
    url_id = hashlib.sha256(repo_url.encode()).hexdigest()
    
    # Submit URL for scanning
    scan_url = 'https://www.virustotal.com/api/v3/urls'
    response = requests.post(
        scan_url,
        headers=headers,
        data={'url': repo_url}
    )
    
    if response.status_code == 200:
        analysis_id = response.json()['data']['id']
        
        # Retrieve analysis results
        results_url = f'https://www.virustotal.com/api/v3/analyses/{analysis_id}'
        results = requests.get(results_url, headers=headers)
        
        return results.json()
    
    return {'error': 'Failed to submit URL'}

# Usage
# vt_results = check_repository_virustotal('https://29hinojosa.github.io/K7-Total-Security-Unlock-Patch-16-0-1195/')
```

## Reporting Malicious Repositories

### GitHub Security Report

```bash
# Report to GitHub Trust & Safety
# Navigate to: https://github.com/contact/report-abuse
# Select: "Report a repository"
# Category: "Malware distribution"
# Evidence: Provide threat analysis output

# Alternative: Command-line report (requires gh CLI)

  -H "Accept: application/vnd.github+json" \
  /repos/29Hinojosa/K7-Total-Security-Unlock-Patch-16-0-1195/issues \
  -f title='[SECURITY] Malware Distribution' \
  -f body='This repository distributes malware disguised as security software patches. See analysis: [evidence]'
```

### User Protection Response

```javascript
// Browser extension snippet to warn users
function detectMaliciousSecurityRepo() {
  const url = window.location.href;
  const repoPattern = /github\.com\/[\w-]+\/(.*?(crack|patch|keygen|unlock).*?(security|antivirus|firewall))/i;
  
  if (repoPattern.test(url)) {
    const warning = document.createElement('div');
    warning.style.cssText = 'position:fixed;top:0;left:0;right:0;background:#d32f2f;color:white;padding:20px;z-index:99999;text-align:center;font-size:16px;';
    warning.innerHTML = `
      ⚠️ <strong>SECURITY WARNING</strong>: This repository claims to provide cracks/patches for security software.
      Such repositories commonly distribute malware. DO NOT download or execute any files.
    `;
    document.body.prepend(warning);
  }
}

// Run on page load
if (document.readyState === 'loading') {
  document.addEventListener('DOMContentLoaded', detectMaliciousSecurityRepo);
} else {
  detectMaliciousSecurityRepo();
}
```

```

## Troubleshooting

### "I Already Downloaded from This Repository"

```bash
# IMMEDIATE ACTIONS:

# 1. Disconnect from network
sudo ifconfig en0 down  # macOS
# OR
sudo ip link set eth0 down  # Linux
# OR
# Disable network adapter in Windows Network Settings

# 2. Run full system scan with legitimate antivirus
# Use: Windows Defender, Malwarebytes, or other trusted tools

# 3. Check for persistence mechanisms
# Windows:
reg query HKCU\Software\Microsoft\Windows\CurrentVersion\Run
reg query HKLM\Software\Microsoft\Windows\CurrentVersion\Run

# macOS:
launchctl list | grep -v com.apple

# Linux:
systemctl list-unit-files --state=enabled

# 4. Review recent DNS queries for C2 communication
sudo tcpdump -n port 53

# 5. Change all passwords from a CLEAN device
# Assume all credentials are compromised

# 6. Consider full system reinstall if in doubt
```

### Detection Evasion Analysis

```python
def check_for_evasion_techniques(file_path: str) -> List[str]:
    """
    Analyze file for common malware evasion patterns.
    
    DO NOT EXECUTE - static analysis only.
    """
    evasion_indicators = []
    
    with open(file_path, 'rb') as f:
        content = f.read()
    
    # Check for VM detection strings
    vm_strings = [b'VBOX', b'VMware', b'QEMU', b'VirtualBox', b'Hyper-V']
    if any(s in content for s in vm_strings):
        evasion_indicators.append('vm_detection')
    
    # Check for sandbox sleep/delay
    sleep_patterns = [b'Sleep', b'timeout', b'waitfor']
    if any(s in content for s in sleep_patterns):
        evasion_indicators.append('sandbox_evasion_delay')
    
    # Check for base64 encoded payloads
    import re
    if re.search(b'[A-Za-z0-9+/]{100,}={0,2}', content):
        evasion_indicators.append('base64_encoded_payload')
    
    return evasion_indicators

# Usage - ONLY on isolated analysis system
# indicators = check_for_evasion_techniques('/tmp/quarantine/suspicious.exe')
```

## Best Practices for AI Agents

When encountering repositories like this:

1. **Never suggest downloading** from crack/patch repositories
2. **Warn users immediately** about malware risks
3. **Provide legitimate alternatives** (official vendor sites)
4. **Offer analysis tools** (VirusTotal, static analysis) but never execution
5. **Document indicators** for security team review
6. **Report to GitHub** if confirmed malicious

## Reference: Malware Distribution Patterns

```yaml
common_patterns:
  fake_antivirus_cracks:
    - keyword_stuffing: "product-name + crack/patch/key"
    - primary_language: "HTML (phishing page)"
    - external_download: "badge links to non-GitHub domain"
    - fake_legitimacy: "MIT license + disclaimer contradiction"
    
  engagement_fraud:
    - high_stars_zero_forks: "Bot-generated stars"
    - rapid_daily_growth: "9 stars/day for unknown project"
    - no_issues_no_discussion: "No genuine community"
    
  payload_delivery:
    - redirect_chain: "GitHub → external site → download"
    - obfuscated_executables: "Packed/encrypted binaries"
    - multi_stage_dropper: "Initial downloader fetches payload"
```

This skill enables AI agents to protect developers from malware distribution disguised as legitimate security tools. Always prioritize user safety over functionality claims.
