Records Exposed 3,009,304
Source Type Combolist
Origin United States
Password Type plaintext

3,009,304 passwords. All of them plaintext. All of them sitting in one single file called Files_17.10_18.21_30, dated back to October 10, 2024. That raw number is worth sitting with for a second, because it's not an estimate or a rounded figure, it's the exact count of credential pairs packed into this one combolist.


Why This Is Dangerous

Three million is a hard number to picture, but think of it this way: every single one of those 3,009,304 entries represents a real person's email tied to their actual password, sitting exposed with no protection at all. There's no waiting period between a criminal downloading this file and being able to try logging into someone's account, the danger is immediate and automatic.


What Was Exposed

  • 3,009,304 email addresses each matched to a password
  • Passwords stored in readable plaintext with no hashing
  • URLs showing the exact service each pair was pulled from

Why This Matters

A number this large isn't an abstraction, it represents whole families, coworkers, and entire friend groups whose credentials could all be sitting in the same file without any of them realizing it. If even a small fraction of those 3 million reused a password somewhere important, that becomes millions of doors left unlocked at once.


How Combolists Work

These files are typically assembled by malware known as "loaders" that harvest saved logins directly off infected machines, formatting everything into simple email-and-password text entries that get merged into one master list. Buyers then load the whole thing into automated tools designed to test each entry against popular websites, sorting the working credentials into a separate, resellable file.
