CLOUDSBASE 261 Leak Exposes Exactly 1,893,682 Records Online

Not 1.9 million, not "almost two million." The file known as CLOUDSBASE 261 contains exactly 1,893,682 stolen records, down to the last entry, uploaded by a Telegram user on 12-Feb-2025. That level of precision is not a coincidence, it is what happens when malware logs every single credential it grabs, one line at a time.

Why This Is Dangerous

An exact figure like 1,893,682 is a reminder that these numbers are not estimates or rounded guesses, they come directly from counting the lines in a stolen file. Each one of those lines is a working, or once working, set of credentials that someone can plug into a login form, wich is exactly why precision matters here.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each login
• 1,893,682 total records exposed

Why This Matters

With nearly 1.9 million records in a single file, the chances that your information is one of them are not small. Attackers who obtain a batch this size often break it into seperate smaller lists and sell pieces of it individually, meaning your data could be recirculating in ways that go far beyond this one original leak.

How Stealer Logs Work

Every entry in a file like CLOUDSBASE 261 traces back to an infected device somewhere, running malware that silently reads saved browser passwords and sends them back to whoever controls the infection. At this scale, it usually means thousands of separate machines were compromised before the results were merged into one large log and released.
