Saved Login URLs Exposed in BlackCloud’s 105,184-Record Leak

Buried inside a 105,184-record BlackCloud stealer log is a detail that's easy to overlook but genuinely worth pausing on: every single record includes the exact URL of the site each stolen password unlocks. Uploaded by a Telegram user in early October 2025, this dump doesn't just hand over usernames and passwords, it hands over a map of exactly where to use them.

Why This Is Dangerous

A password by itself is a puzzle piece. A password matched to the exact login page it came from is a finished picture. Because this data was pulled straight off infected devices, the credentials were still working at the time they were captured, and because they're stored in plaintext, no attacker needs any special tools to read them. That combination, live passwords paired with their exact destination, is what makes stealer logs so much more dangerous than an old leaked spreadsheet.

What Was Exposed

Across the 105,184 records in this log, the following was found:

• Email addresses belonging to real users
• Plaintext passwords with no encryption applied
• URLs specifying exactly which website or service each login opens
• 105,184 total records in the file

Why This Matters

When the exact login URL travels alongside the password, an attacker doesn't waste time guessing which bank, email provider, or shopping site to try. They go straight to the source. This is especially concerning for anyone who has reused a password acrossed multiple accounts, since one leaked credential paired with its URL can open several doors at once instead of just one.

How Stealer Log Works

Stealer malware gets onto a device through things like cracked software, fake installers, or malicious links, then quietly runs in the background collecting whatever the browser has saved. It logs stored passwords, the URLs tied to them, cookies, and autofill fields, packaging it all together before sending it off to the attacker. That package eventually becomes a file like this one, often shared or sold on Telegram not long after it's collected.

Check If You Are Affected

If any of your saved logins might be sitting in a file like this, its definately worth finding out now rather than later. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, giving you a clear answer on whether you're part of this BlackCloud leak or any other breach that's been recorded.
