Inside the 2,867-Account Stealer Log Shared on Telegram

In March 2025, a stealer log labeled "3.5K MIX" surfaced on a Telegram channel, containing 2,867 sets of stolen login credentials pulled from malware-infected computers. Picture a batch of browsers across dozens of different devices, each one quietly copied by info-stealing malware and bundled together into a single file: emails, plaintext passwords, and the web addresses where they were used, all mixed together and shared with anyone who wanted them.

Why This Is Dangerous

A "mixed" stealer log like this one is dangerous precisely because it isn't tied to one single service. The 2,867 credential sets inside touch a wide mix of sites and accounts, which means the fallout isn't limited to a single platform. Anyone whose login appears in this file has a password sitting in plaintext, ready to be tried against other accounts.

What Was Exposed

• Email addresses
• Plaintext passwords
• Login URLs tied to each account

Why This Matters

Mixed credential dumps are a favorite tool for credential stuffing attacks, where automated tools take a list like this one and try each email and password pair across banking, shopping, and email login pages. Because the passwords were captured in plaintext, there's no encryption standing between an attacker and account takeover. From there, it's a short step to identity theft or financial fraud if any of those accounts hold payment details or personal information.

How Stealer Log Dumps Like This Get Made

Stealer malware infects a device through things like cracked software, fake installers, or malicious email attachments. Once installed, it silently harvests every saved password, cookie, and autofill entry from the browser and sends it back to whoever is running the malware. Logs from many infected devices then get bundled together, exactly like this "3.5K MIX" file, and passed around on dark web forums and Telegram channels.

Check If You Are Affected

With 2,867 accounts in this single leak, there's a real chance your email address is one of them. HEROIC's free breach scanner checks your information against more than 400 billion leaked records, including stealer logs like this one, so you can find out in seconds and take action before anyone else does.
