HEROIC analysts found a Telegram file simply named 600000, dated April 2021, that actually holds 102,506 records of email addresses, plaintext passwords, and the URLs those logins open. The file name overstates the count, but the real number is still substantial, and every entry in it is a working credential pair. Scan your email now to find out if you are one of the 102,506.

102,506 Passwords, No Encryption in Sight

There is nothing subtle about this file. Every password inside sits in plain readable text, meaning anyone who opens it can start testing logins immediately, with no decoding step and no delay between finding a record and using it.


What the 600000 File Contains

  • Email Addresses: single out which account to target with phishing or password reset attempts.
  • Plaintext Passwords: readable exactly as entered, ready to use the moment they are seen.
  • URLs: show precisely where each password pair logs in, removing any guesswork.

What Happens if Your Password Is in Here

Blunt as it sounds, a plaintext password with an email attached is close to a finished product for an attacker. That combination can be used to log into the exact account it was captured from, and into any other account that happens to share the same password.


Where a File Like 600000 Comes From

A combolist collects email and password pairs from various earlier sources and packages them into a single file for testing against other sites. Its name does not point to any one company being hacked. It is simply a working list built to sort still active logins from dead ones.


Yours Might Be One of the 102,506

Get a clear answer by choosing to scan your email right now. If your address is included, change that password immediately and update it anywhere else you used it, since a plaintext password is usable the instant someone reads it. Check both personal and work email addresses to be thorough.
