If you think the biggest cybersecurity threat is a Fortune 500 company getting hacked, you're looking in the wrong direction.
Today's breach landscape has undergone a seismic shift that most people haven't noticed. Our database now tracks 18.9 billion compromised records from 13,025 distinct breaches—and the pattern reveals something troubling: the era of massive one-time database breaches is being eclipsed by something far more insidious.
The Rise of Stealer Logs: A New Threat Paradigm
7,240 breaches in our database are classified as stealer logs—representing 56% of all tracked incidents. This isn't a minor trend. It's a complete transformation of how cybercriminals operate.
Unlike traditional breaches where hackers penetrate a company's defenses and extract millions of records at once, stealer logs work differently. Malware silently harvests credentials, cookies, and autofill data directly from infected devices—often from individuals, not corporations. These logs are then sold in underground markets, creating a continuous pipeline of fresh credentials.
The most recent breaches in our database paint this picture clearly. Five separate stealer log collections were uploaded to Telegram channels just days ago in February 2026, containing everything from private cloud credentials to browser authentication tokens. These aren't anomalies—they're the new normal.
What Makes Stealer Logs So Dangerous
Traditional breaches were events you could respond to. A company announces a compromise, you change your password, and you move on. Stealer logs operate under the radar.
Here's why they're particularly dangerous:
- They bypass company security entirely by targeting the endpoint—your personal device
- They capture active session cookies, meaning hackers can access accounts even without passwords
- They're distributed across thousands of small incidents rather than one publicized breach, so you might never know you're compromised
- They often include plaintext passwords, which our data shows appear in 8,973 breaches—nearly 69% of all incidents tracked
When your credentials end up in a stealer log, they're typically packaged with everything a criminal needs: saved passwords, browser cookies, cryptocurrency wallets, and even screenshots of your activity.
The Massive Breaches Still Matter
While stealer logs dominate by volume, the historical mega-breaches continue to cast long shadows. The XSS.IS Combolist alone contains 2.47 billion records with email addresses, usernames, and plaintext passwords. Combine that with the Misc Combolists collection at 1.9 billion records, and you're looking at over 4 billion compromised credential pairs circulating in criminal ecosystems.
These massive compilations become the foundation for credential stuffing attacks—automated attempts to log into thousands of services using stolen username-password combinations. If you've reused passwords across sites (and statistically, you probably have), these collections are why that's catastrophic.
The Verifications.io breach from 2019 exposed 722 million records containing email addresses, phone numbers, and names—personal identifiers that fuel phishing campaigns, social engineering attacks, and identity theft to this day.
Your Exposure Is Probably Larger Than You Think
Here's the uncomfortable reality: 47% of breaches contain plaintext passwords. Not hashed, not encrypted—readable text that can be used immediately.
Our data shows email addresses appear in 12,515 breaches when you combine the various categorizations. Phone numbers show up in 1,018 breaches. First and last names together appear in over 1,400 breaches each.
If you've had the same email address for more than five years, used the same password on multiple sites, or saved credentials in your browser, you're statistically likely to be in multiple breach databases.
Three Actions You Must Take Today
1. Check your exposure immediately. Don't guess whether your credentials have been compromised—know for certain. LeakedSource lets you search across our entire 18.9 billion record database to see exactly where your information appears.
2. Enable two-factor authentication everywhere. Even if your password is compromised, 2FA creates a second barrier that stealer logs can't easily bypass. Focus first on email, financial, and social media accounts.
3. Use unique passwords for every account. Password managers make this feasible. The days of memorizing passwords are over—the threat landscape demands a different approach.
The Threat Landscape Isn't Slowing Down
With 7,908 verified breaches in our database and new stealer logs appearing daily, the pace of credential compromise shows no signs of declining. The evolution from massive corporate breaches to distributed stealer log operations means more attack vectors, more frequent exposures, and more difficulty detecting when you've been compromised.
The question isn't whether your credentials are in a breach database—it's how many times they appear and what you're going to do about it.
Find out where you stand. Search your email, phone number, or username at LeakedSource to see your exposure across all 13,025 tracked breaches. Knowledge is the first step to protection.
