Researchers Uncover Bugatti Cloud Leak Of 5,757 Passwords

HEROIC researchers observed a stealer log tied to Bugatti Cloud, the third part in a batch a Telegram user uploaded on June 25, 2026. Investigators found 5,757 records inside, including email addresses, plaintext passwords, and the URLs of the sites those credentials belong to.

What Analysts Noticed About This Batch

Watching how this file moved through Telegram, researchers noted it was released alongside several other numbered parts on the same day, a sign that whoever compiled it had a sizable amount of stolen data ready to distribute at once, seperate from anything released before.

Because the passwords were stored in plaintext, anyone who obtained the file could use the logins immediately, without needing to crack or decode anything.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why Outside Observers Take Leaks Like This Seriously

From a security researcher's viewpoint, the danger is rarely just the 5,757 accounts on this list. It is what happens next, when attackers reuse those same credentials elsewhere through credential stuffing, hoping people used the same password for their email, bank, or shopping accounts too.

That pattern is what regularly turns a modest stealer log into cases of account takeover, identity theft, and financial fraud that ripple out well beyond the original file.

How Investigators Say Logs Like This Get Made

According to researchers who track this activity, stealer logs come from infostealer malware planted on a victim's device through fake downloads, cracked software, or phishing attachments. The malware quietly collects saved browser passwords and autofill data, then sends it back to whoever is controlling it.

From there, the stolen data is often broken into smaller, numbered parts, like this one, and pushed out across Telegram channels were buyers are waiting.
