description
Detect and warn about malicious firewall software impersonation and licensing bypass schemes
triggers
["analyze this firewall repository for security risks","is this Fort Firewall repository legitimate","check if this firewall download is safe","evaluate this firewall patch or crack","scan this repository for malware indicators","verify authenticity of Fort Firewall download","detect software piracy or trojan distribution","identify fraudulent security software"]
Primary language is HTML (landing page, not real software)
Topics include "crack", "patch", "key", "serial"
No actual source code in repository
External download links instead of GitHub releases
2. Content Analysis
import re
defanalyze_readme_for_malware_indicators(readme_text):
"""Detect malware distribution patterns in README content."""
red_flags = {
'license_bypass': [
r'crack', r'patch', r'keygen', r'serial',
r'product key', r'activation', r'license key'
],
'av_evasion': [
r'disable.*antivirus', r'disable.*protection',
r'false positive', r'whitelist.*antivirus'
],
'external_download': [
r'\.github\.io', r'bit\.ly', r'tinyurl',
r'mediafire', r'mega\.nz'
],
'social_engineering': [
r'full version', r'pro version', r'premium unlocked',
r'no subscription', r'lifetime license'
]
}
findings = {}
for category, patterns in red_flags.items():
matches = []
for pattern in patterns:
if re.search(pattern, readme_text, re.IGNORECASE):
matches.append(pattern)
if matches:
findings[category] = matches
return findings
# Example usage
readme_content = """
Run FortFirewall_Setup_3.14.1_Patch.exe as Administrator
The product key patch will self-inject
Your antivirus may flag the patcher as a PUP
Temporarily disable real-time protection during installation only
"""
results = analyze_readme_for_malware_indicators(readme_content)
print(f"Threat indicators found: {results}")
# Output: {'license_bypass': ['patch', 'product key'], # 'av_evasion': ['disable.*protection', 'false positive']}
3. GitHub API Verification
import os
import requests
defverify_repository_legitimacy(owner, repo):
"""Check repository metadata for fraud indicators."""
api_url = f"https://api.github.com/repos/{owner}/{repo}"
headers = {"Authorization": f"token {os.getenv('GITHUB_TOKEN')}"}
response = requests.get(api_url, headers=headers)
if response.status_code != 200:
return {"error": "Repository not found"}
data = response.json()
warnings = []
# Check for suspicious indicatorsif data.get('language') == 'HTML':
warnings.append("Primary language is HTML (likely landing page)")
ifnot data.get('license'):
warnings.append("No license specified (uncommon for legitimate OSS)")
topics = data.get('topics', [])
suspicious_topics = ['crack', 'patch', 'keygen', 'serial', 'key']
found_suspicious = [t for t in topics ifany(s in t for s in suspicious_topics)]
if found_suspicious:
warnings.append(f"Suspicious topics: {found_suspicious}")
if data.get('fork') isFalseand data.get('forks_count', 0) == 0:
warnings.append("Zero forks (unusual for popular project)")
if data.get('open_issues', 0) == 0:
warnings.append("Zero issues (suspicious for active project)")
return {
"legitimate": len(warnings) == 0,
"warnings": warnings,
"metadata": {
"language": data.get('language'),
"license": data.get('license'),
"topics": topics,
"forks": data.get('forks_count'),
"issues": data.get('open_issues')
}
}
# Example
result = verify_repository_legitimacy("lloyd17x", "fort-firewall-security-fix")
print(result)
4. URL Safety Check
import requests
from urllib.parse import urlparse
defcheck_download_link_safety(url):
"""Analyze download URLs for malware distribution patterns."""
parsed = urlparse(url)
# High-risk hosting patterns
risky_domains = [
'github.io', # User pages (not official releases)'bit.ly', 'tinyurl.com', 'goo.gl', # URL shorteners'mediafire.com', 'mega.nz', 'zippyshare.com'# File hosts
]
domain = parsed.netloc.lower()
ifany(risky in domain for risky in risky_domains):
return {
"safe": False,
"reason": f"Hosted on {domain} instead of GitHub Releases",
"recommendation": "Use official GitHub Releases only"
}
# Legitimate pattern: github.com/owner/repo/releasesif'github.com'in domain and'/releases/'in parsed.path:
return {
"safe": True,
"reason": "Official GitHub Release"
}
return {
"safe": False,
"reason": "Unknown hosting source",
"recommendation": "Verify with official project documentation"
}
# Test malicious link from repository
malicious_url = "https://lloyd17x.github.io/fort-firewall-security-fix/"
result = check_download_link_safety(malicious_url)
print(result)
# Output: {"safe": False, "reason": "Hosted on github.io instead of GitHub Releases", ...}
Safe Alternatives
Installing Legitimate Fort Firewall
# Download from official GitHub releases
$latestRelease = Invoke-RestMethod -Uri "https://api.github.com/repos/tnodir/fort/releases/latest"
$downloadUrl = $latestRelease.assets | Where-Object { $_.name -like "*setup*.exe" } | Select-Object -ExpandProperty browser_download_url
# Verify it's from github.com/tnodir/fort
if ($downloadUrl -match "github.com/tnodir/fort") {
Write-Host "Downloading from official source: $downloadUrl"
Invoke-WebRequest -Uri $downloadUrl -OutFile "FortFirewall_Setup.exe"
} else {
Write-Error "URL verification failed - not official source"
}
Verifying Downloaded Files
# Check digital signature (legitimate software should be signed)
Get-AuthenticodeSignature "FortFirewall_Setup.exe" | Select-Object Status, SignerCertificate
# Calculate file hash and compare with official release
$hash = Get-FileHash "FortFirewall_Setup.exe" -Algorithm SHA256
Write-Host "SHA256: $($hash.Hash)"
# Compare with hash published on official GitHub release page
Reporting Malicious Repositories
If you encounter repositories like this:
Report to GitHub:
# Visit the repository and click "Report repository" # Or use GitHub's DMCA/abuse form
❌ Topics include "crack", "patch", "keygen", "serial"
Always Verify:
✅ Official repository owner/organization
✅ Source code is present and matches project language
✅ Downloads from GitHub Releases (not external links)
✅ Valid open-source license
✅ Active community and maintainers
Conclusion
This skill helps AI agents identify and warn about software impersonation and malware distribution schemes. The repository in question is a textbook example of how attackers disguise malware as legitimate security software. Always verify authenticity before downloading any security tools.
