Dark Web Intel: SnowCloud Stealer Log Exposes 2,135,139 Logins

Dark web intel teams flagged a large file circulating on Telegram in July 2025, labeled SNOWCLOUD-VALIDSULP-FROMTRAFFIC.txt_part_11. It is only one part of a larger series, and this single piece alone contains 2,135,139 records, making it one of the bigger stealer logs to surface this year.

Why This Is Dangerous

A file of this size definately raises the stakes. Over two million records means over two million chances for someone's password to be reused somewhere important, and the fact that it was split into numbered parts suggests the group behind it is organized enough to process and resell data at scale.

What Was Exposed

• 2,135,139 total records
• Email Addresses
• Plaintext Passwords
• URLs linking each credential to its login page

Why This Matters

Large stealer log dumps like this one tend to circulate quietly for weeks or months before wider attention catches up to thier scale. That head start gives criminals plenty of time to test logins, sell access, and move on to the next target before victims even know their information is out there.

How Stealer Logs Work

Traffic logs like this one are built by malware sitting on infected devices, scooping up saved browser credentials, then routing them to a collector who sorts everything into files by validity, hence the valid label in the file name. Only working, live logins make the cut, which is part of why dark web intel analysts treat these dumps as high priority.

Check If You Are Affected

With over two million records involved, checking your exposure is worth doing right away. HEROIC's free breach scanner searches more than 400 billion compromised records, this dump included, so you can find out in seconds if your email or passwords appear.
