If You’re in the Bugatti Cloud Stealer Logs, 10,321 Records Leaked

HEROIC analysts identified a stealer log file named "Bugatti_Cloud" uploaded to Telegram on 21 August 2026, containing 10,321 records of stolen endpoint data, including email addresses, associated URLs, and plaintext passwords pulled directly from infected devices.

Why This Is Dangerous

Unlike a database leak from one company, a stealer log captures whatever a piece of malware found sitting on an infected computer, meaning the passwords in this file are current and were working at the time of infection. Because the data includes the exact URLs each password was used on, an attacker can go straight to the right login page for banking, email, or shopping accounts without any guesswork.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to the accounts the credentials belong to

Why This Matters

Stealer log data is especially valuable to criminals because it reflects real, active sessions rather than old, possibly changed passwords. With 10,321 records in this file, attackers can run automated credential stuffing against banks and email providers, leading to account takeover, identity theft, and financial fraud for anyone whose device was infected.

How Stealer Logs Work

A stealer log is generated by malware, often called an infostealer, that infects a device and silently harvests saved browser passwords, autofill data, and session information before sending it back to the attacker. The data is then packaged into a file like this one, split into parts, and sold or shared on platforms such as Telegram, often within days of the infection.

Check If You Are Affected

Use HEROIC's free breach scanner to check whether your email address appears in this stealer log or anywhere across HEROIC's database of more than 400 billion breached records. If you find a match, change that password immediately, run a malware scan on your device, and enable two-factor authentication wherever possible.
