Dark Web Intel: 3,569,648 Credentials From 3.5ml Full Private Part3

HEROIC analysts have identified a combolist file named 3.5ml full private part3, uploaded to Telegram on January 12, 2026. It contains 3,569,648 records pairing email addresses with plaintext passwords and the URLs those logins unlock. The only way to know if you're affected is to scan your email.

Why a File This Large Is Dangerous

Scale changes how attackers use a leak. A file of this size is valuable enough that multiple groups will likely automate login attempts against it, running each pair against popular sites within hours of the file circulating. With millions of working pairs to test, even a small success rate still hands over thousands of real accounts.

What Was Exposed

• Email Addresses: pinpoints who the account belongs to, which attackers use to personalize follow on scams.
• Plaintext Password: already readable text, so it can be tried against a login page the moment it's downloaded.
• URLs: tells attackers exactly which site or app each stolen password opens.

Why Reused Passwords Make This Worse

Millions of pairs means a large share of them are reused somewhere else, since most people recycle a handful of passwords across many accounts. That turns one leaked login into a master key for email, shopping, or financial accounts tied to the same password. Account takeover and fraudulent purchases are the most common outcomes once a working pair is confirmed.

How a Combolist of This Size Comes Together

Large combolists like this one are typically stitched together from many smaller leaks collected over time, then cleaned, deduplicated, and repackaged as a single file for resale or free distribution. HEROIC analysts confirmed the pairs in this file are formatted for immediate use rather than scraped from an old, dead source.

Is Your Login One of the 3,569,648 in This Leak?

Scan your email to see if it turns up in this file or any other leaked dataset. If it does, change that password everywhere you used it, and set a unique password for every account going forward. Check both your personal and work email, since this kind of file often mixes both.
