The combolist "Files_17.10_18.21_62" leaked 4,618,546 plaintext email and password pairs on Telegram on 10-Oct-2024. That's the whole story in one line, and it's already enough reason to check your own exposure.


Why This Is Dangerous

No encryption, no hashing, no delay. Every one of those 4,618,546 credential pairs works the moment someone downloads the file, which is exactly why combolists like this one get weaponized so quickly after they surface.


What Was Exposed

  • 4,618,546 email addresses paired with plaintext passwords
  • URLs tied to the specific accounts each credential unlocked
  • Zero protection standing between the data and anyone who wants it

Why This Matters

Reused passwords turn one leaked account into many. If your credentials are in this file, assume every account using the same password is exposed too, not just the one the data was originally tied to.


How This Combolist Was Made

Timestamp-style filenames like this one usually mark an automated export from a stealer operation or a large scraping job. Multiple smaller sources get merged, cleaned, and released as one file, wich is how a leak this size gets built without any single dramatic hack behind it.


Check If You Are Affected

Skip the guesswork. HEROIC's free scanner checks your email against more than 400 billion leaked records, including this exact combolist, and tells you plainly whether you need to act.
