929,033 people had their login details packaged into a file labeled "File number 328" from the 1106.Url_Login_Password series, uploaded to Telegram on June 17, 2024, the same day two other files from the same operation also went public.


Why This Is Dangerous

Seeing multiple files drop from the same source on a single day is a sign of an active, ongoing credential theft operation rather than a one time incident. File 328 alone contains 929,033 email, password, and URL combinations, each one ready to be tested against real accounts.


What Was Exposed

  • 929,033 unique email addresses
  • Plaintext passwords with absolutely no protection layer
  • URLs showing exactly which service each login belongs to

Why This Matters

When a threat actor is prolific enough to release multiple numbered files in the same day, it usually means their malware infrastructure is still actively collecting data from victims. Anyone caught in file 328 should asume their credentials could occassionally resurface again in a future numbered release.


How This Stealer Log Series Works

The 1106.Url_Login_Password operation appears to rely on infostealer malware that continuously harvests saved logins from infected machines, then splits the haul into separate numbered files for distribution. This keeps individual files manageable in size while still delivering a steady, near constant supply of fresh credentials to buyers.
