The 3.5ml_mix Dump Holds Exactly 2,470,788 Stolen Login Pairs

2,470,788 email and password pairs surfaced in a combolist file called 3.5ml_mix, uploaded to Telegram in January 2026. HEROIC analysts reviewed the file and confirmed it holds live email addresses, plaintext passwords, and the URLs they unlock. The only way to know if you're affected is to scan your email.

Why This Combo of Data Travels So Fast

A combolist pairs a working email address directly with its plaintext password, so there is no cracking or guessing involved. Anyone who downloads this file can try each pair against email providers, banking apps, or shopping sites right away. Because the passwords are already readable, the gap between finding this file and breaking into an account is close to zero.

What Was Exposed

• Email Addresses: identifies exactly who you are and gives attackers a direct channel for targeted phishing.
• Plaintext Password: readable the moment it was downloaded, so it can be used to log in immediately, with no cracking required.
• URLs: shows attackers exactly which site or service each password unlocks, making targeted login attempts fast and easy.

What Happens If These Credentials Get Reused

If any of these passwords match ones used on other accounts, attackers can walk straight into email, banking, or shopping logins without guessing anything. A hijacked email often becomes the key to resetting passwords on dozens of other services, opening the door to identity theft and financial fraud. Even an account that seems unimportant can be used to send phishing messages to your contacts.

How a Combolist File Like This Gets Built

A combolist is assembled by collecting email and password pairs from many smaller leaks and scraped credential dumps, then merging them into one large file for resale or free distribution. HEROIC analysts reviewed this file and found the pairs still active and formatted for direct use. Unlike a single company's systems being broken into, a combolist draws from many sources at once, which is why the same password often shows up tied to several different accounts.

Is Your Email One of the 2,470,788 Exposed in 3.5ml_mix?

The fastest way to find out is to scan your email against this and other leaked datasets. If your email turns up, change the password tied to it everywhere you reused it, and give each account its own unique password going forward. This applies whether the exposed address is a personal inbox or a work email, since attackers do not treat the two differently.
