Telegram ‘Mail’ Stealer Log Quietly Exposed 11,839 Logins

In June 2026, a Telegram user quietly uploaded a stealer log labeled "Mail" containing 11,839 records pulled from malware-infected computers. Nobody announced it publicly. There was no press release, no warning, just a file dropped into a channel where anyone could download it. Inside were email addresses, plaintext passwords, and the login URLs tied to each one.

Why This Quiet Leak Deserves Attention

Stealer log dumps like this one rarely make headlines, but that's exactly what makes them dangerous. There's no company statement, no forced password reset, no notification email. The people affected likely have no idea their credentials are sitting in a Telegram channel right now, fully readable, waiting for someone to use them.

What Was Exposed

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

Why This Matters

Because the passwords are stored in plaintext and matched to specific login pages, this data is ready to use the moment someone opens the file. Attackers run these lists through automated credential stuffing tools, quietly testing each email and password pair against email providers, banks, and shopping accounts. Reused passwords make account takeover, identity theft, and financial fraud almost effortless for whoever finds this log.

How This Stealer Log Was Likely Built

Stealer malware infects a device through a cracked download, a fake browser update, or a malicious attachment, then silently scans the browser's saved passwords, autofill entries, and login history. The results are packaged into a log file and shared or sold on Telegram, often for free to build a reputation before larger paid dumps. Because the process runs in the background, victims typically never notice anything happened until their accounts are already compromised.

Check If You Are Affected

If your email or passwords could be part of this 11,839-record leak, silence is not a safe assumption. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs exactly like this one, so you can find out quietly, on your own terms, before an attacker acts on it.
