changedetection.io-osint-processor 0.0.3

OSINT Reconnaissance Processor for changedetection.io with Email Security, DNSSEC, SSH & SMTP

🔍 OSINT Reconnaissance Changedetection.io Processor Agent

Comprehensive network intelligence and security monitoring leveraging changedetection.io

This is a processor agent plugin for changedetection.io change detection and notification dashboard.

Monitor your infrastructure for unexpected changes. Detect unauthorized modifications to SSL/TLS certificates, DNS records, BGP routing, open ports, WHOIS registration details, HTTP security headers, and TLS cipher configurations. Perfect for security teams, DevOps engineers, SRE teams, and OSINT practitioners who need continuous visibility into their infrastructure's security posture. Get instant notifications when certificates are about to expire, DNS records change, new vulnerabilities appear, or network paths are rerouted—before they become security incidents or outages.

Use the existing text filters built into changedetection.io to trim out information you don't need and keep only what's relevant to you. Easily connect change alerts to Discord, Slack, email, and 90+ other notification backends, leveraging the awesomeness of changedetection.io's powerful notification system.

1. Create a watch with URL: https://example.com
2. Select processor: OSINT Reconnaissance

Then see your full OSINT report as a text change which can be easily connected to Discord, email, ntfy, matrix, ms-teams, slack and 90+ other notifications.

✨ Features

Network Intelligence

• DNS Records (A, AAAA, MX, NS, TXT, SOA, CAA)
• DNSSEC Validation (cryptographic signatures, chain of trust)
• WHOIS Lookup (registration, nameservers, expiry)
• BGP/ASN Info (ISP, network ownership)
• Traceroute (network path analysis)
• MAC Address (vendor identification via IEEE OUI)

Email Security

• SPF Records (Sender Policy Framework anti-spoofing)
• DMARC Records (email authentication policy)
• DKIM Records (email signature verification)
• Email security posture assessment

Security Analysis

• SSL/TLS Certificates (subject, issuer, validity, SANs)
• Cipher Suites (SSL 2.0 → TLS 1.3)
• Vulnerability Scanning (Heartbleed, ROBOT, CCS Injection, CRIME, etc.)
• HTTP Security Headers (HSTS)
• SSH Fingerprinting (banner, version, host keys, algorithms)
• SMTP Security (encryption, authentication methods)

Application Layer

• HTTP Fingerprinting (headers, cookies, redirects, CDN/WAF detection)
• Port Scanning (common service ports)
• OS Detection (TTL-based fingerprinting)
• SSH Server Analysis (port 22)
• SMTP Server Analysis (ports 25, 587, 465)

Performance

• Parallel Mode (4-5x faster scans)
• Serial Mode (safer, easier to debug)
• Configurable modules (enable/disable any scan)
• Real-time status updates

Example settings

Pro-tips:

• Use the "Only trigger when unique lines appear in all history" text filter setting to limit to new events that has not been seen before (ignores text moving around like IP addresses in a pool).

⚠️ Note: Requires cryptography>=43,<45 for sslyze compatibility.

🔒 SOCKS5 Proxy Support

The OSINT processor supports SOCKS5 proxies for enhanced privacy and anonymity. This is perfect for:

• 🧅 Tor onion routing (socks5h://127.0.0.1:9050)
• 🛡️ Anonymous reconnaissance without exposing your IP
• 🌍 Geolocation bypass via SOCKS5 proxy servers
• 🔐 Privacy-focused monitoring of sensitive targets

⚠️ CRITICAL SECURITY WARNING: DNS Leaks

Always use socks5h:// (not socks5://) to prevent DNS leaks!

• ✅ socks5h://127.0.0.1:9050 - Remote DNS resolution (secure)
• ❌ socks5://127.0.0.1:9050 - Local DNS resolution (LEAKS YOUR QUERIES)

The h in socks5h:// forces hostname resolution through the SOCKS5 proxy, preventing your DNS queries from leaking to your local DNS server.

What we do to prevent leaks:

• DNS scans use TCP (port 53) through SOCKS5 - no local DNS
• HTTP scans skip local DNS resolution when proxy is configured
• SSH/SMTP pass hostnames to proxy - remote DNS only
• If SOCKS5 connection fails, we block the request (no fallback to direct connection)

Without these protections, your real IP and DNS queries would be exposed even when using a proxy!

Supported Steps:

Step	SOCKS5 Support	Notes
DNS Records	✅ Supported	Uses DNS-over-TCP (port 53) through SOCKS5
HTTP Fingerprinting	✅ Supported	Full proxy support via requests library
SSH Fingerprinting	✅ Supported	TCP connections proxied via python-socks
SMTP Fingerprinting	✅ Supported	MX server scans through SOCKS5 proxy
DNSSEC Validation	⚠️ Partial	DNS-over-TCP possible (not yet implemented)
Email Security (SPF/DMARC/DKIM)	⚠️ Partial	DNS-over-TCP possible (not yet implemented)
WHOIS Lookup	⚠️ Partial	TCP port 43 compatible (library limitation)
TLS Analysis	⚠️ Partial	TCP-based but SSLyze doesn't support SOCKS5
Port Scanning	❌ Not supported	Raw socket connections
Traceroute	❌ Not supported	ICMP/UDP packets incompatible
BGP/ASN Info	❌ Not supported	API lookups (not yet implemented)
OS Detection	❌ Not supported	Raw socket fingerprinting
MAC Address Lookup	❌ Not supported	Layer 2 local network only

Note: When a SOCKS5 proxy is configured, unsupported steps are automatically skipped and listed in the scan output.

⚠️ Important: Only SOCKS5 proxies are supported. HTTP/HTTPS proxies will be rejected with an error message.
