Your Data May Be Exposed: The MegaCloud 12.12 Leak Hit 30,935 Accounts

HEROIC analysts logged a combolist file titled "31K FRESH Mix HITS By MegaCloud 12.12" after it was uploaded to Telegram in December 2024. Despite the "31K" in its name, the file we verified contains 30,935 records combining email addresses, plaintext passwords, and site URLs.

Why the MegaCloud 12.12 Leak Is Dangerous

Every record in this file pairs a working email address with a readable, plaintext password. There is no cracking step for an attacker to work through, just automated tools feeding the list into login forms across the web to see which accounts open up.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs

Why Nearly 31,000 Exposed Accounts Matters

A list of this size gives attackers a large enough pool to run automated credential stuffing at scale. If your password shows up here and you have reused it elsewhere, your email, banking, or social accounts could be tested and compromised without you ever noticing until the damage is done.

How a "Fresh Mix" Combolist Like This Is Assembled

Sellers who label a file "fresh" are marketing it as recently collected and likely to still work. In practice, these mixes are usually assembled by merging credentials from several smaller sources, breaches, stealer logs, or older leaks, into one file, then branded under a name like MegaCloud to build the seller's reputation on Telegram.
