The rounded name hides a precise count: HEROIC analysts confirmed the combolist file labeled 1.4k valids, uploaded to Telegram on January 12, 2026, actually holds exactly 1,431 records of email addresses, plaintext passwords, and the URLs those logins open. The only way to know if you're affected is to scan your email.


Why Every One of These 1,431 Pairs Still Works

The word valid in this file's name isn't marketing. It means each of the 1,431 pairs was tested and confirmed to log in successfully before the file was shared. That single step removes the guesswork attackers usually face, since there is nothing dead or outdated left to sort through.


What Was Exposed

  • Email Addresses: identifies the account owner and gives attackers a target for phishing attempts.
  • Plaintext Password: stored as readable text and already confirmed to work on first use.
  • URLs: shows attackers precisely which login page each confirmed password belongs to.

Why a Small, Confirmed File Is Still a Big Problem

A smaller file with every login confirmed working is often more dangerous than a much larger one full of dead entries, since attackers can move straight to using the accounts instead of filtering first. That means account takeover, unauthorized purchases, or a locked out inbox can happen within hours of this file spreading.


How Logins Get Verified Before Being Labeled Valid

After a batch of stolen credentials is collected, attackers often run automated tools that attempt to log into each account and keep only the pairs that succeed. What remains gets packaged and labeled valid, exactly like this 1.4k valids file, then sold or shared since confirmed logins carry more value than untested ones.


Is Your Password One of the 1,431 Confirmed Valid?

Scan your email to check whether your address appears in this file or any other leaked dataset. If it does, change that password everywhere it was reused and set a unique password for each account going forward. This applies to personal and work email alike, since a confirmed combolist rarely separates the two.
