Stop scrolling for a second. A combolist called "Files_17.10_18.21_61" dumped 4,980,304 plaintext email and password pairs onto Telegram on 10-Oct-2024, and if you haven't checked whether your information is in it, that's a gap worth closing right now, not after something goes wrong.


Why This Is Dangerous

Nearly 5 million working login pairs is more then enough for large scale automated attacks against banks, email providers, and shopping sites. This isn't theoretical risk sitting in some dusty archive, it's active data that criminals are testing against real accounts as you read this.


What Was Exposed

  • 4,980,304 email addresses tied directly to plaintext passwords
  • URLs showing exactly which accounts each stolen login belonged to
  • Credential data with absolutely no encryption slowing anyone down

Why This Matters

Every day this file stays uncontained, more of those nearly 5 million accounts get tested, cracked, or drained. There's no benefit to waiting, and honestly, a lot of people just don't relize how quickly stolen credentials get put to use once they hit a public channel.


How This Combolist Came Together

Files with this timestamp style naming convention are typically automated exports from stealer malware campaigns or large scraping operations, merged and packaged for quick distribution. The size alone, nearly 5 million lines, suggests multiple smaller batches were consolidated into one release.


Check If You Are Affected

Don't put this off. HEROIC's free scanner checks your email against more than 400 billion leaked records, including this exact combolist, and gives you a definite answer in under a minute so you can lock down your accounts before anyone else gets to them first.
