Once a criminal has the file Files_17.10_18.21_43 in hand, they're holding 5,079,875 working email and password combinations pulled together and posted to Telegram in October 2024. What happens next depends entirely on what they choose to do with it.


Why This Is Dangerous

With a combolist this size, an attacker can run automated credential stuffing scripts against banking portals, streaming services, and email providers all at once. Because every password here is stored in plaintext, there's no cracking step required, wich means the attack can start within minutes of downloading the file.


What Was Exposed

  • 5,079,875 email and password combinations in one file
  • Passwords recorded in plain, unencrypted text
  • URLs tying each credential pair back to its original login page

Why This Matters

Attackers with a file like this can do more than just log into one account. They can take over email addresses and use password reset tools to spread into other services, drain loyalty points or gift card balances, or resell verified working logins to seperate buyers at a markup. A single leaked password can turn into a chain of compromised accounts before the victim even notices.


How a File Like This Gets Made

Combolists like Files_17.10_18.21_43 are typically assembled by combining data from older breaches with fresh output from infostealer malware. Someone runs the merged list through a checker tool that confirms which logins still work, discards the dead ones, and packages the surviving accounts into a clean file ready for resale or free distribution on Telegram.


Check If You Are Affected

Knowing what attackers can do with a file this size should be reason enough to check your own exposure. HEROIC's free scanner searches more than 400 billion leaked records and will show you imediately if your email and password ended up in this combolist or one just like it.
