How the Mix Mail Access Stealer Log Leaked 14,339 Passwords

In early May 2026, HEROIC threat intelligence analysts identified a stealer log file uploaded to Telegram under the name "Mix Mail access," containing 14,339 records. Despite the name suggesting a single mailbox, the file is a mixed batch covering email addresses, plaintext passwords, and the URLs of the login pages each credential was stolen from.

How a Batch of 14,339 Logins Ends Up on Telegram

This kind of file is the direct output of infostealer malware, malicious software that infects a device (often through a pirated download, fake software crack, or malicious email attachment) and quietly harvests everything saved in the browser: usernames, passwords, and the exact web address each one belongs to. Once collected, the data is packaged into a single log and uploaded, in this case to a Telegram channel where it can be downloaded or purchased by anyone.

What Was Exposed in the Mix Mail Access Log

• Email addresses
• Plaintext passwords
• URLs of the login pages tied to each credential

Why This Matters for the 14,339 People in This File

Because the passwords are stored as plain, readable text, no cracking is required. Anyone with the file can attempt to log in immediately. Since people frequently reuse passwords, attackers routinely take a batch like this and test the same email and password combination across banking, shopping, and social media sites, a tactic known as credential stuffing. A single reused password can open the door to account takeover, financial fraud, or identity theft.

Why Stealer Logs Keep Growing in Size

Unlike a single hacked website, stealer logs pull data from whatever accounts happen to be saved on an infected device at the time, which is why they can mix hundreds or thousands of unrelated accounts and services into one file. A log of 14,339 records like this one likely represents credentials collected from many different infected computers and combined into a single dump before being sold or shared.

Check If Your Email Was in This Batch

With more than 14,000 records in circulation, it is worth checking whether your email address is among them. HEROIC's free breach scanner searches over 400 billion leaked records, including stealer logs like this one, so you can see your exposure and update any reused passwords before someone else logs in first.
