Our data breach tracker shows the most recent ransomware attacks. We index data directly from threat actor leak sites and track various ransomware threat actors and where they’re leaking the stolen data.
This gives security teams early access to breach data. See how the Breachsense tracker works for details on what we index and how we verify it. For monthly trends and analysis, check our ransomware reports. If your company gets hit, or your vendor leaks your data in their breach, you can respond before attackers exploit it.

How to Search for Data Leaks
Data leaks surface across multiple sources. Knowing where to search helps you find exposed credentials before attackers exploit them.
For security teams: Data leak monitoring continuously searches for your domains across dark web marketplaces and breach forums. Get alerts when employee credentials or company data surfaces.
For penetration testers: Our API integrates full credential details directly into your testing workflow. For a quick check, the dark web scan shows an overview of the credentials we’ve indexed for any domain.
What sources matter most for data leak search:
- Third-party breaches - When vendors get breached, your data may be exposed. Search for your domains in breach compilations.
- Infostealer logs - Malware harvests credentials directly from browsers. These logs appear on infostealer channels within hours of infection.
- Ransomware leak sites - The breach tracker above shows companies hit by ransomware. Search for your vendors here.
- Dark web marketplaces - Stolen credentials are bought and sold on darknet markets. Continuous monitoring catches your data when it’s listed for sale.
