4,686,725 Passwords Leaked in a Single Telegram Combolist

4,686,725. That's how many email and password combinations sat inside a file called Files_17.10_18.21_96 when it appeared on Telegram on October 10, 2024. It's a number large enough to represent a mid-sized city, except every single entry here is a real account somebody trusted to stay private.

Why This Is Dangerous

What makes a number like this genuinely alarming isn't just its size, it's the fact that every password inside was stored in plaintext. There's no barrier at all between the raw data and an attacker's login attempt, so the moment this file changed hands, all 4,686,725 credentials became immediately usable.

What Was Exposed

• Email addresses for millions of individual accounts
• Unencrypted plaintext passwords paired with each address
• URLs revealing exactly which service each login belongs to

Having all three pieces together, email, password, and destination, is what lets criminals skip straight past guesswork and go directly to attempting logins at scale.

Why This Matters

A file this large doesn't stay contained to one download. Copies spread across multiple channels almost imediately after release, meaning the real number of people who eventually see this data likely far exceeds whoever grabbed the original upload.

How Combolists of This Scale Get Made

Building a file with nearly five million entries usually means combining several smaller leaks, stealer logs, or breach dumps into one master list, then cleaning duplicates so the final product runs smoothly through automated credential stuffing tools. The scale here suggests a fairly sophisticated aggregation effort behind the scenes.

Check If You Are Affected

With a file this large, the odds that your email is somewhere inside it are worth taking seriously. HEROIC's free scanner checks against a database of over 400 billion leaked records so you can find out in seconds rather than wondering. If you get a match, change that password today.
