Records Exposed 530
Source Type Stealer log
Origin United States
Password Type plaintext

A small file called Good Emails made its way onto Telegram in February 2026, and inside it were 530 records that had already been sorted and labeled as "good," meaning working, real login combinations pulled from an infostealer log.


Why This Is Dangerous

The word "good" in the title is what makes this file worth paying attention to despite its small size. Someone took the time to sort through a larger batch of stolen data and pull out the entries that were confirmed to still work, which means every one of these 530 records is more likely to be active right now.


What Was Exposed

  • 530 total records
  • Email addresses
  • Plaintext passwords
  • URLs tied to each login

Why This Matters

It started, most likely, with malware quietly installed on someone's computer through a cracked download or a fake update prompt. That malware copied saved browser passwords in the background without the user ever noticing, then sent everything back to whoever was running the infection.


How Stealer Logs Work

From there, the raw stolen data gets sorted. Someone tests each login to see wich ones still work, throws out the dead or duplicate entries, and keeps only the "good" ones, exactly what happened here. The result is a smaller but more dangerous file, since every entry left has already been proven functional, and it gets shared or sold seperate from the original, messier batch.


Check If You Are Affected
