Eleven thousand two hundred fifty two. That's the exact count sitting inside a CryptogoL12-branded stealer log that a Telegram user posted around April 29, 2026. It's smaller than some of the leaks making headlines, but every single one of those rows is a real person's saved login.


Why This Is Dangerous

Size doesn't determine severity here. A stealer log of just over 11,000 entries can still contain banking portals, work email, and personal accounts, all captured at once from the same infected device. Attackers don't care how big the file is, they care whether the credentials still work, and freshly stolen ones usually do.


What Was Exposed

  • Endpoint and host information from compromised devices
  • Email addresses linked to each infected session
  • Plaintext passwords lifted straight from browser storage

Why This Matters

A relatively small stealer log like this one tends to fly under the radar, wich in some ways makes it more dangerous. Nobody's writing news articles about it, so the people affected may never find out unless they actively check. Meanwhile the file keeps circulating quietly among buyers looking for easy targets.


How Stealer Logs Work

These logs come from malware planted on a victim's computer, often hiding inside pirated software or a fake update prompt. Once active, it scrapes whatever the browser has saved: usernames, passwords, cookies, even autofill payment details in some cases. The stolen data gets bundled into a text file and shared or sold, exactly like the one behind this report.
