The Full Logs Stealer Dump Put 3,242 Stolen Credentials Online

What HEROIC Analysts Found

In July 2026, HEROIC's threat intelligence team identified a stealer log file, labeled Full Logs, after it was uploaded to Telegram by an individual user. The file contained 3,242 records, each pairing an email address with a plaintext password and the web address it was used to log into.

Why This Is Dangerous

Stealer logs like this come directly from malware that ran on someone's device and captured their saved logins as they typed. That means the passwords in this file are recent and, in many cases, still active. Because they are stored in plaintext, anyone who gets this file can use the credentials immediately with no extra effort.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated login URLs

Why This Matters

Because stealer log data is pulled straight from an infected device, it tends to be more accurate and current than data from old breaches. Criminals prize logs like this one because the credentials are more likely to still work. That makes them useful for credential stuffing across banking, email, and social media accounts, and for account takeover, identity theft, and financial fraud once a working login is found.

How Stealer Logs Work

A stealer log is generated by malware, often called an info-stealer, that infects a computer and quietly harvests everything saved in the browser: usernames, passwords, cookies, and the sites they belong to. Once collected, the data is packaged into a log file and sold or shared on Telegram channels and dark web marketplaces, sometimes within days of the infection. Unlike a database breach, a stealer log reflects the victim's actual browsing habits and current passwords.

Check If You Are Affected

HEROIC's free breach scanner checks your email address against a database of more than 400 billion breached and leaked records, including stealer logs like Full Logs. If you find a match, change that password right away, along with any other account where you reused it.
