The Mail Acces 1178 Leak: 955 Passwords Exposed. Yours Might Be One.

HEROIC analysts flagged a stealer log file named "Mail Acces 1178 Mix Fr Jb Valid 100," uploaded to a Telegram channel in August 2025. The file contains 955 records marketed by its uploader as "valid," meaning the email addresses, plaintext passwords, and login URLs inside are claimed to be currently working.

Why This Is Dangerous

This is not a stale, years-old dump. The "valid" label means someone has likely tested these credentials and confirmed they still log in, which makes the data far more useful to an attacker than an unverified list. There is no guesswork involved, just a direct path into 955 email accounts.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated mail login pages

Why This Matters

An inbox is often the gateway to everything else a person owns online. Whoever holds this list can reset passwords on banking, shopping, and social accounts, read private conversations, and lock the real owner out entirely. If any of these passwords are reused elsewhere, the damage from credential stuffing can spread far beyond the original mailbox.

Yours Might Be One: Inside a Verified Stealer Log

Verified, or "valid," logs like this one start the same way as any stealer log: infostealer malware infects a device, often through pirated software or a malicious attachment, and quietly copies saved browser passwords and the web addresses they belong to. Before selling or sharing the file, the person behind it runs a checker tool that tests each login and strips out anything dead, leaving only working accounts like the 955 found here.

Check If You Are Affected

The only way to know if your email is one of the 955 in this file, or in any other leak, is to check. HEROIC's free breach scanner searches more than 400 billion leaked records in seconds, so you can find out today and change any exposed passwords before someone else uses them.
