Look Before You Scan
Active scanning alerts defenders and consumes scope time. Passive recon gathers intelligence from existing data — Shodan, DNS records, certificate transparency, paste sites — before you touch the target network.
HackFast Passive Recon panel on Attack Surface consolidates host summaries, service tiles, and expandable details so you can map the environment quietly and plan targeted active tests.
Passive Recon Panel Features
- Host summary with key metadata at a glance
- Stat tiles for quick counts — ports, services, technologies
- Coloured sections for organized scanning progress
- Expandable service details without panel clutter
- Status badge and skeleton placeholders during data load
- Manual host JSON paste at panel bottom for custom imports
Educational: Passive vs. Active Recon
| Type | Examples | Detection Risk |
|---|---|---|
| Passive | DNS lookup, CT logs, Shodan, OSINT | Very low |
| Light active | HTTP banner grab, TLS handshake | Low–medium |
| Heavy active | Full port scan, vulnerability scan | High |
Start passive, identify high-value targets, then run focused active scans through HackFast fusion agents only where scope allows.
Workflow: Passive to Active
- Import or gather passive data into Attack Surface
- Review Passive Recon panel — note unexpected services
- Use AI Insights Briefing for structured target summary
- Plan active scans on highest-value hosts only
- Deploy targeted nmap or ffuf from Chats with agent confirm
