Files_17.10_18.21_35 sounds like a random file name, and it is, but hidden behind it are 3,412,586 real login combinations that were dumped on Telegram on October 10, 2024 for anyone to download.

Why This Is Dangerous

Combolists like Files_17.10_18.21_35 get traded and resold constantly on dark web forums and Telegram channels alike. Once a file this large is public, it doesn't stay in one place, it gets copied, repackaged, and passed around, wich means the exposure from this single leak keeps spreading long after the original upload.


What Was Exposed

  • Email addresses gathered from previously compromised sources
  • Passwords listed in plain, readable text
  • URLs tying each credential pair to the site it was used on

Why This Matters

Criminals don't need to hack anything new when a list like this exists, they just need a script that tries each of the 3,412,586 combinations against other popular websites. If even a small percentage of people reused their password somewhere else, that's still tens of thousands of accounts that can be taken over with almost no effort.


How This Type of List Gets Assembled

Rather than a single breach, a combolist is usually stitched together over time from many smaller sources, old database leaks, stealer logs, and public dumps that get merged and deduplicated. By the time Files_17.10_18.21_35 reached Telegram, it had likely passed through several hands, each one adding more records before the final version was shared.


Check If You Are Affected

It's easy to asume a file like this doesn't concern you, but with 3.4 million records inside, the odds say otherwise for a lot of people. Use HEROIC's free scanner to check your email against more than 400 billion breached and leaked records and get a clear, immediate answer.
