Xavier_Ulp Dump Contains Exactly 281,573 Leaked Passwords

Not a rounded estimate, not a ballpark figure, but an exact count: 281,573. That is precisely how many records sit inside the Xavier_Ulp - 376293 Xavier_Group dump uploaded to Telegram in April 2026, each one pairing an email address with a plaintext password and a matching URL.

Why This Is Dangerous

A specific number like this tells you the leak was carefully cataloged, wich means whoever compiled it treated the data as a real, organized asset rather than a messy pile of scraps. That level of organization makes it easier for buyers or other criminals to sort, search, and act on the information quickly. Because the passwords are plaintext, there is nothing standing between that organized list and immediate misuse.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs tied to each login
• 281,573 total records confirmed exposed

Why This Matters

An exact figure like 281,573 makes the scope of this breach hard to dismiss as exaggeration. Every one of those records belongs to a real person who now has to worry about whether their password shows up somewhere it should not. If even a fraction of these people reused their password on other accounts, the fallout could reach far beyond the original 281,573 records.

How Stealer Logs Work

This breach is a stealer log, meaning the data most likely came from infostealer malware that infected devices and quietly recorded saved browser passwords, cookies, and autofill entries. That harvested information gets sent back to whoever controls the malware, then organized into precise files like this one before being shared or sold. It is a process that occured quietly on each infected device long before the finished file ever showed up on Telegram.

Check If You Are Affected

With numbers this specific, it is worth getting an equally specific answer about your own exposure. HEROIC's free breach scanner checks your email or password against a database of more than 400 billion leaked records, giving you a fast, clear result you can actually trust.
