Records Exposed 3,111,338
Source Type Combolist
Origin United States
Password Type plaintext

3,111,338 passwords are now sitting in plaintext on a Telegram channel, free for anyone to download. The file responsible, "Files_17.10_18.21_75," was uploaded on October 10, 2024, and it's been quietly available ever since.

Why This Is Dangerous

Plaintext means readable. No decryption, no password cracking tools, no technical skill of any kind is required to use what's inside this file. Whoever downloads it can start testing logins immediately.

What Was Exposed

  • Just over 3.1 million email and username combinations
  • Passwords stored with absolutely no encryption
  • The URLs each login was captured alongside

Why This Matters

A combolist this size doesn't discriminate. It contains logins for everyday people, small business owners, and anyone else whose credentials ended up in an older breach that eventually fed into this file. Reusing a password anywhere near this list is a gamble most people don't realize they're taking.

How a File Like This Comes Together

Rather than a single hack, a combolist like this one is compiled over time from multiple smaller breaches, then cleaned up and packaged for distribution. The process is almost entirely automated, scripts pull emails and passwords from raw breach data, filter out duplicates, and format everything into one neat, dangerously usable file, ready to garuntee results for whoever downloads it.

More than 400 billion leaked records sit in HEROIC's database, including this specific combolist. A free scan of your email address will tell you imediately whether you're one of the 3,111,338 people whose data is now in circulation.
