How the 213 Combolist Leaked 205,209 Plaintext Passwords

205,209 is the exact count HEROIC analysts logged for a combolist known simply as 213, uploaded to Telegram and dated 10 June 2019. Each of those 205,209 rows pairs an email address with a plaintext password and the login URL it came from. A file this size doesn't happen from one leak, it's built up over time by combining working credentials from many sources. Scan your email to see if your address is among them.

Why this is dangerous

At more than 200,000 rows, this file gives an attacker enough raw material to run large-scale automated login attempts, known as credential stuffing, across dozens of popular services at once. Because every password is stored in plaintext, there's no cracking delay involved, each pair is ready to test the moment the file is opened.

What was exposed

• Email addresses that work as the username for most account logins.
• Plaintext passwords readable immediately, with no decryption step needed.
• Login URLs identifying exactly which service each credential pair unlocks.

Why this matters

A combolist this large increases the odds that any one person's password shows up more than once, especially if it was reused across several accounts over the years. Even though the file dates back to 2019, old plaintext passwords still work today on any account where the owner never got around to changing them.

How a combolist this size gets built

A combolist grows by merging credential pairs pulled from smaller leaks, phishing hauls, and successful login attempts into one master file. Entries are typically tested in bulk to weed out ones that no longer work, which is part of how a file like 213 ends up with a precise, six-figure count rather than a rough estimate.

How do you find out if you're in this file?

Run a scan your email to check your address against this combolist and every other breach HEROIC has indexed. If your email turns up, change that password right away, update it anywhere else you reused it, and turn on multi-factor authentication for the account. Check both personal and work email addresses, since a file this large can easily include either.
