Breach Data Discovery: Find Leaked Credentials Automatically

Introduction to Breach Data Discovery

Credential stuffing attacks are among the most effective ways to gain initial access. When people reuse passwords across services, a breach from one site can compromise accounts on your target. The challenge is finding which credentials have been leaked and mapping them to your target's personnel.

HackFast's breach scanning automates this entire process. Once you've discovered email addresses through OSINT mapping, HackFast can scan for leaked credentials associated with those domains, automatically mapping results to people in your project and alerting you when leaks are found.

How Breach Scanning Works

Breach scanning in HackFast follows a simple workflow:

1. Discover Email Domains: Through OSINT mapping, you find email addresses like user@targetcompany.com
2. Trigger Domain Scan: Manually trigger a breach scan for the domain (targetcompany.com)
3. Automatic Discovery: HackFast searches breach databases for all credentials associated with that domain
4. Intelligent Mapping: Results are automatically matched to people in your project based on email addresses
5. Notification: You receive alerts when leaks are discovered

All discovered credentials are saved with full raw data, ensuring you have complete breach information including passwords, hashes, usernames, and breach source details.

Manual Trigger System

Breach scanning is manual to conserve API credits and give you control:

• Per-Person Scanning: Trigger scans from individual person profiles
• Domain-Level Results: One scan finds all credentials for the entire domain
• 24-Hour Cooldown: Each domain can only be scanned once per 24 hours to prevent duplicate requests
• Persistent Timers: Cooldown timers persist across sessions

The cooldown system ensures you don't waste credits on repeated scans while still allowing you to re-scan domains after the cooldown period expires.

Leaks View: Comprehensive Breach Data

The Leaks tab in OSINT mapping shows all discovered breach data:

• Grouped by Database: See which breach each credential came from
• Summary Statistics: Total leaks, unique emails, and breach sources
• Detailed View: See email, username, password, hash, and breach date for each leak
• Raw Data Access: View the complete original breach entry
• Person Mapping: See which people each leak is associated with

All breach data is stored in its raw format before any parsing, ensuring you have the complete original information from the breach database.

Person Details Integration

When leaks are found, they automatically appear in person profiles:

• Leaked Credentials Section: Shows all breaches associated with that person
• Quick Access: View passwords, hashes, and breach details directly in the profile
• Breach Source: See which database each leak came from
• Breach Date: Know when the breach occurred

This integration makes it easy to see which discovered personnel have leaked credentials, helping you prioritize credential stuffing targets.

Browser Notifications

HackFast sends browser notifications when leaks are discovered:

• Real-Time Alerts: Get notified immediately when leaks are found
• Permission-Based: Browser will request notification permission on first use
• Non-Intrusive: Notifications appear even if HackFast is in the background

This ensures you never miss important credential discoveries, even if you're working on other tasks.

Practical Use Cases

Credential Stuffing Campaigns

Use discovered passwords to attempt login on your target's services. Many people reuse passwords, so a breach from one site might work on your target's login portal.

Password Pattern Analysis

Analyze discovered passwords to identify patterns. If multiple people from the same company use similar password structures, you can craft targeted password attacks.

Social Engineering

Knowing someone's leaked password can inform social engineering attacks. Reference the breach in phishing emails to increase credibility.

Conclusion: Automate Credential Discovery

Breach data discovery transforms credential stuffing from a manual, time-consuming process into an automated workflow. By scanning domains and automatically mapping results to people, HackFast helps you quickly identify which credentials might be valid for your target.
