What Is a Stealer Log? Evolution Logs 65 Leaked 9,896 Records

If you've never heard the term "stealer log" before, the Evolution Logs Free 65 dump from May 1, 2026 is about as clear an example as you'll find. A Telegram user handed out 9,896 records for free, all pulled from computers infected by information-stealing malware, branded under the batch name "1100 Pcs" to signal how many machines were hit.

Why This Is Dangerous

A stealer log is dangerous precisely because it's not a guess or a leaked database dump from some old website, it's a live snapshot of what was sitting in a person's browser the moment their machine got infected. That means the credentials inside are often current, still working, and tied directly to accounts people log into every day.

What Was Exposed

• Email addresses harvested straight from browser autofill and saved logins
• Plaintext passwords with no hashing or protection whatsoever
• URLs pinpointing exactly which sites and services each credential unlocks

Why This Matters

Nearly 10,000 records is a large enough batch that it's not just a handful of unlucky people, it's a genuine cross section of everyday internet users. Because the file was given away for free, it will likely get copied, reposted, and recirculated on other channels for months, wich means the exposure window here doesn't close after one day, it keeps going.

How Stealer Logs Work

Here's the short version: malware sneaks onto a device (often through cracked software or a phishing link), scans the browser's password manager and autofill data, then exports everything into a text file. That file, the "log," gets grouped with others from the same malware campaign and named for tracking purposes, like "Evolution Logs Free 65" or the number of PCs it came from. From there it's uploaded to Telegram or dark web forums and either sold or given away.

Check If You Are Affected

Understanding what a stealer log is only helps if you actually check whether you're in one. HEROIC's free scanner cross references your email against more than 400 billion leaked and stolen records, including logs exactly like this 9,896-record dump, so you don't have to asume you're safe, you can just find out.
