PortHunter release

🛡️ PortHunter - Advanced Port & Process Scanner

PortHunter is an advanced PowerShell tool suite for network port analysis and process correlation. It generates professional HTML reports for security audits and system troubleshooting.

📋 Overview

PortHunter includes two complementary scripts designed for different use cases:

Script	Purpose	Method	Speed	Best For
PortHunter_Scan.ps1	Active service discovery & port scanning	Active probing of common ports (TCP/UDP) + banner grabbing	🐢 Slow (minutes)	Service discovery, penetration testing
PortHunter_Established.ps1	Advanced process-port correlation	Local socket inspection (listening + established) — no active probes	🚀 Fast (seconds)	Security audits, troubleshooting

🎯 PortHunter_Scan.ps1

Key Features

• 📡 Active Port Scanning - TCP/UDP scanning of common ports
• 🚩 Banner Grabbing - Service identification via banners
• 🔗 Process Correlation - Attempts to map discovered/open ports to processes when possible
• 📈 Comprehensive Reporting - Detailed statistics and service analysis

Scanning Behavior

• Performs active probes (TCP connect/SYN, UDP probes) against a predefined list of common ports ($commonPorts).
• Attempts banner grabbing to identify service and version information.
• When possible, correlates discovered open ports to local processes (if the target is local or the probe establishes a connection that can be mapped).

Usage

# Basic active scan (TCP + UDP common ports)
.\PortHunter_Scan.ps1

# TCP ports only
.\PortHunter_Scan.ps1 -SkipUDP

# Fast scan mode (reduce ports / parallelism)
.\PortHunter_Scan.ps1 -FastScan

🌐 PortHunter_Established.ps1

Key Features

• 🔍 Multi-Method Correlation - 4 different techniques to identify processes
• 🎯 Confidence System - High/Medium/Low reliability ratings
• 📊 Advanced Reporting - Method details and confidence levels
• ⚡ Optimized Performance - Analyzes only listening ports and established connections (local socket inspection)

Correlation Methods

1. NetStat Analysis - Most reliable native method (parses existing socket table)
2. Active Connection Enumeration - Uses Get-NetTCPConnection / Get-NetUDPEndpoint and related APIs
3. Handle Analysis - System handle inspection (requires admin; uses handle enumeration)
4. Network Statistics - Alternative correlation method (supplemental data)

Usage

# Basic local socket inspection (TCP + UDP)
.\PortHunter_Established.ps1

# Skip UDP endpoints
.\PortHunter_Established.ps1 -SkipUDP

# Fast mode (limited correlation methods)
.\PortHunter_Established.ps1 -FastScan

📊 Detailed Comparison

Feature	PortHunter_Scan	PortHunter_Established
Primary Purpose	Service discovery & active scanning	Process-port correlation (local sockets)
Methodology	Active probing of common ports (TCP/UDP) + banner grabbing	Local socket inspection (listening + established) — no active probes
Ports Analyzed	Common ports + active scanning	Listening ports and established connections only
Speed	Minutes (depends on ports/parallelism)	Seconds
Banner Grabbing	Comprehensive for scanned ports	Limited to existing connections where banner data is available
Confidence Levels	❌ Not available	✅ Implemented (High/Medium/Low)
Multi-Method	❌ Primary method only	✅ 4 methods
Admin Required	Recommended for certain probes (raw socket/UDP)	Recommended for handle analysis and full correlation
Use Case	Penetration testing, discovery	Security audits, troubleshooting

📁 Output Structure

Each script generates timestamped HTML reports:

• AdvancedPortScan_YYYYMMDD_HHMMSS.html (PortHunter_Scan)
• PortScanReport_YYYYMMDD_HHMMSS.html (PortHunter_Established)

Report Sections

• 📈 Summary - Scan statistics
• 🔍 Detailed Analysis - Port and process table
• 🚨 High-Risk Ports - Critical ports highlighted
• ⚙️ Process Summary - Grouped by process
• 🚩 Service Banners - Service identification banners

Best Practices

• Always run as Administrator for complete results
• Verify unknown processes on high-risk ports
• Analyze service banners for vulnerable versions
• Keep reports for audits and future comparisons

🔧 Customization

Modifying High-Risk Ports

# Edit the $HighRiskPorts variable in scripts
$HighRiskPorts = @(21, 22, 23, 25, 53, 135, 139, 443, 445, 993, 995, 1433, 3389, 5900)
