HEROIC Uncovers Mix 20.06 1231 Leak of 174,784 Passwords

While monitoring dark web channels in June 2025, HEROIC analysts came across a stealer log file labeled simply "mix 20.06 1231," quietly uploaded to a Telegram channel on 19-Jun-2025. Buried inside were 174,784 records, each combining a stolen email address, a plaintext password, and the website URL where that login was captured.

Why the Mix 20.06 1231 Leak Is So Dangerous

The generic, throwaway name of this file is part of what makes it dangerous. Files like "mix 20.06 1231" often slip past attention because they do not carry a recognizable brand name, yet the data inside is just as real and just as usable as any named breach.

Every password in this dump was stored in plaintext, so there is nothing standing between an attacker and a working login.

What Was Exposed in This Stealer Log

• Email addresses belonging to real people
• Plaintext passwords with no encryption
• URLs identifying the exact site each login was used on

Why the 174,784 Exposed Records Matter

Because so many people reuse the same password on multiple sites, a single leaked email and password pair can unlock far more than one account. Attackers automate this process, feeding stolen pairs into scripts that quietly test them across banking, shopping, and email platforms in what is known as credential stuffing.

A successful match can lead directly to account takeover, and from there to identity theft or financial fraud that the victim may not notice untill the damage is already done.

How This Stealer Log Ended Up on Telegram

Stealer logs are produced by infostealer malware, malicious code that infects a device through a pirated program, a fake installer, or a booby trapped attachment. Once active, it scans the browser for saved passwords, autofill records, and open sessions.

Everything it collects is compiled into a single file and given a short, forgettable name like "mix 20.06 1231" before being posted for anyone on Telegram to grab. Generic naming like this is common when a log is shared quickly, without much effort to seperate or organize the stolen data.
