Change Your Password: File 93 Leaked 3.75 Million Logins

Go change your password. That's the short version of what you need to know about Files_17.10_18.21_93, a combolist uploaded to Telegram on October 10, 2024 that turned out to hold 3,750,460 email and plaintext password pairs once researchers looked inside it.

Why This Is Dangerous

The reason the advice comes before the explanation is simple, plaintext credentials paired with working URLs don't require any decoding or cracking. An attacker can act on this data the second they open the file, which means the window between exposure and actual damage can be measured in minutes rather than days.

What Was Exposed

• Email addresses connected to millions of accounts
• Passwords stored with zero encryption
• URLs pointing directly to the affected services

Nearly 3.75 million lines is enough to automate attacks against dozens of platforms in parallel, which is exactly what tools built for this purpose are desgined to do.

Why This Matters

This file was one of several released around the same date under a similar naming pattern, suggesting an uploader working through a much larger archive in pieces. Even if your specific email isn't in this file, a seperate one from the same series might still contain it.

How a Combolist This Size Gets Used

Once a file like this circulates, it typically feeds directly into credential stuffing tools that automatically try each pair against major websites. Any successful login gets pulled out into a smaller, more valuable list. The original 3.75 million records become the starting pool for a much more targeted second wave of attacks.

Check If You Are Affected

Before assuming you're in the clear, run a free check with HEROIC's scanner, which compares your email against more than 400 billion leaked records collected from breaches just like this one. It takes seconds, and if you get a hit, changing that password is the one step that actually matters.
