6,754,936 leaked credentials. That's the number that matters most about Files_17.10_18.21_25, a file uploaded to Telegram and dated October 10, 2024. The filename came second. The damage came first.


Why This Is Dangerous

Working backward from the number, each one of those 6,754,936 rows is a working email and password pair, sitting in plaintext, free for anyone who downloads the file to use however they like. The scale alone makes this attractive to criminals running automated attacks.


What Was Exposed

  • Email addresses connected to real accounts
  • Passwords stored without any encryption
  • URLs marking exactly where each login is used

Why This Matters

Most people learn about a leak through its name, but the name isn't what puts them at risk, the data is. Files_17.10_18.21_25 could have been called anything and it would still contain 6,754,936 exposed login records that criminals can act on imediately.


How a File Like This Ends Up With So Many Records

Numbers this large usually come from combining several smaller sources, stealer logs, older breaches, phishing hauls, into one master list before it's split and distributed. Files like this occassionally resurface months later under a slightly different filename, recycled by a new seller. By the time it reaches Telegram under a name like Files_17.10_18.21_25, it has already passed through several hands.


Check If You Are Affected

Forget the filename, focus on the exposure. HEROIC's free scanner checks your email against more than 400 billion leaked records, so you can find out in seconds if you're one of the 6,754,936 people whose data ended up in this particular file.
