Stealer Log Uploaded by a Telegram User Exposes 8,775 Records

What HEROIC Analysts Found

In July 2026, HEROIC analysts identified a stealer log file that had been uploaded to a public Telegram channel by an individual user. The file contained 8,775 records pulled from malware-infected devices, including email addresses, plaintext passwords, and the exact web addresses those logins belong to.

Why This Is Dangerous

Stealer logs like this one are especially risky because the passwords inside are stored in plaintext and paired directly with the website each one unlocks. There is no cracking or guessing involved. Anyone who downloads this file can simply copy a login and the matching URL, then sign in as if they were the real account owner.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linking each login to the site it belongs to

Why This Matters

Because the same email and password combinations often get reused across multiple accounts, this kind of leak fuels credential stuffing attacks, where automated tools try the same login on banking sites, email providers, and social media until one works. Anyone whose credentials appear in this file is at risk of account takeover until they change their passwords.

How Stealer Logs Work

A stealer log is the output of infostealer malware, a type of program that quietly runs on an infected computer and collects saved passwords, browser autofill data, and session details before sending everything back to the attacker in a single file. Once collected, these logs are often shared or sold in Telegram channels and dark web forums, exactly how this file surfaced, giving buyers ready-made lists of working logins.

Check If You Are Affected

If you think your email address might be part of this or another leak, HEROIC's free breach scanner checks it against a database of more than 400 billion leaked records. Run a quick search to see if your information has been exposed and get guidance on securing your accounts.
