SunCloudNew 1738 - 700 LogsFile sounds like an internal file name, and that's basically what it is, a stealer log dumped on Telegram May 23, 2026 holding 16,180 stolen credential pairs with real consequences for the people inside it.


Why This Is Dangerous

The fallout from a leak like this doesn't stay contained to the moment of infection. Every password in SunCloudNew 1738 sits in plaintext, so once the file starts circulating, each of the 16,180 victims faces ongoing risk from anyone who downloads a copy, not just the original attacker.


What Was Exposed

  • 16,180 email addresses paired with stolen passwords
  • Plaintext password values, unprotected by encryption
  • URLs pinpointing exactly which service each login was taken from

Why This Matters

The real consequence of a leak like this shows up weeks or months later, when a victim discovers a stranger logged into an old account, or a password reset email arrives for a service they forgot they used. Don't asume a stranger logging into an old account is a coincidence. By the time that happens, the credentials from SunCloudNew 1738 have likely already been copied and shared far beyond the original file.


How SunCloudNew Style Logs Get Produced

Files like this one come from infostealer malware running on infected machines, quietly pulling saved browser logins and packaging them for the attacker. The name SunCloudNew 1738 - 700 LogsFile suggests it's one file in a numbered series, wich points to an operator running the same malware campaign repeatedly and releasing fresh batches as new victims get infected.
