ReconX is a powerful command‑line domain reconnaissance toolkit designed for cybersecurity researchers, penetration testers, and network administrators. It performs layered intelligence gathering including DNS, SSL certificate harvesting, TCP port scanning, brute‑force subdomain discovery, and automated HTML/text report generation.

📝 Report Generation
- Plain‑text reports (timestamped)
- Dark‑themed HTML reports
- Subdomain lists
- Brute‑force discoveries
- SSL certificate details
- Open ports
📦 Batch Scanning

Usage
1) Single Domain Quick Scan
python3 ReconX.py > 1 > example.com
2) Single Domain + Brute Force
python3 ReconX.py > 2 > example.com > /path/to/wordlist.txt
3) Multi‑Domain Batch Scan
python3 ReconX.py > 3 > domains.txt
4) Batch + Brute Mode
python3 ReconX.py > 4 > domains.txt > wordlist.txt
Report Output Location
./reconx_reports/- Text: reconx_domain_YYYYMMDD_HHMMSS.txt
- HTML: reconx_domain_YYYYMMDD_HHMMSS.html
Advanced Notes
DNS Resolver Patching
On Ubuntu 24+, local system DNS can misbehave. ReconX defaults to:
- 8.8.8.8 (Google)
- 1.1.1.1 (Cloudflare)
- 9.9.9.9 (Quad9)
Multi‑Thread Settings
Configurable in the source:
- SUBDOMAIN_THREADS
- PORT_THREADS
- BRUTE_THREADS
Raspberry Pi Notes
No need for sudo unless scanning ports < 1024.
