The Bugatti_Cloud Breach Put 4,544 Stolen Credentials on Telegram

Bugatti_Cloud Part026 Stealer Log Breach Overview

HEROIC's threat intelligence team identified a stealer log dataset labeled Bugatti_Cloud Bugatti_Man 18.04.part026 that was uploaded to Telegram in April 2023. The file contained 4,544 compromised records extracted from infected devices, exposing email addresses, plaintext passwords, and the specific URLs where those credentials were used. This is part of a larger series of stealer log dumps shared by the same Telegram user, amplifying the total scope of exposure.

Why This Is Dangerous

Stealer log data is uniquely dangerous because it bypasses every traditional security measure. The passwords are not hashed or encrypted. They are stored exactly as the victim typed them. Combined with the matching URLs, an attacker has everything needed to log into victim accounts within seconds. There is no guesswork involved. The email addresses provide a direct line to each victim, enabling follow-up phishing attacks and social engineering schemes. Criminals who purchase or download these logs can operationalize them immediately with automated tools that test thousands of credential pairs per minute.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (the exact websites each credential belongs to)

Why This Matters

When credentials are leaked in plaintext alongside their associated websites, the risk of credential stuffing and account takeover increases dramaticly. Attackers use automated bots to test stolen credentials across banking portals, email providers, shopping sites, and corporate login pages. A single compromised password that is reused across services can lead to financial fraud, identity theft, unauthorized access to workplace systems, and hijacked personal accounts. The 4,544 records in this dump may seem small, but each record potentialy represents access to dozens of accounts belonging to one victim.

How Stealer Logs Work

Stealer logs originate from infostealer malware that infects a victim's device, usually through malicious email attachments, fake software downloads, or compromised websites. Once active, the malware harvests saved login credentials from web browsers like Chrome, Firefox, and Edge. It also captures cookies, session tokens, and autofill data. All of this information is packaged into log files and transmitted to the attacker's servers. From there, the logs are sorted, bundled, and distributed through Telegram channels, dark web marketplaces, and underground forums. The Bugatti_Cloud series represents one such distribution campain where multiple parts were uploaded sequentially.

Check If You Are Affected

If you have ever saved passwords in your web browser, you could be at risk from stealer log breaches like this one. Use the HEROIC data breach scanner to check whether your email or credentials appear in any of over 400 billion compromised records. The scan is free, fast, and confidential.
