The Bugatti_Cloud Part029 Leak Exposed 11,782 U.S. Accounts

In June 2023, a Telegram user uploaded a stealer log file designated part029 of the Bugatti_Cloud Bugatti_Man series. HEROIC analysts verified the dataset and confirmed it contains 11,782 records tied to U.S.-based accounts, each pairing an email adress with a plaintext password and the URL of the service it was stolen from. This file is now indexed in HEROIC's breach database, which tracks more than 400 billion exposed records across thousands of known data exposures.

Why This Is Dangerous

The passwords in this file are stored in plain text, meaning they are fully readable without any decryption tools or technical knowledge. An attacker can open this file, copy an email and password, and attempt to log in to the matching site immediately. Because many victims reuse the same password across multiple accounts, a single stolen credential can become a master key to email, banking, social media, and cloud storage. The U.S. concentration of these accounts makes them especially attractive targets for automated credential stuffing campaigns that run around the clock.

What Was Exposed

• Email addresses
• Plaintext (unencrypted) passwords
• URLs identifying the exact services the credentials were stolen from

Why This Matters

Stealer logs like part029 are not isolated incidents. The Bugatti_Cloud Bugatti_Man series consists of dozens of numbered part files, each representing a separate batch of harvested credentials. Together they expose tens of thousands of real accounts. For victims, the immediate risk is account takeover: an attacker uses the stolen email and password to log in, locks the real owner out, and then pivots to reset passwords on linked accounts. Financial accounts, email providers, and cloud services are typically the first targets. The presence of site URLs in this dataset means attackers do not need to guess where to strike.

How Stealer Log Breaches Work

A stealer log is produced by infostealer malwere running silently on a victim's computer. The infection usually arrives through a fake software download, a malicious browser extension, or a phishing link. Once installed, the malware records everything the browser autofills, incluing saved passwords, session cookies, and visited URLs. That harvested data is packaged into a log file and sent back to the attacker, who distributes it through Telegram channels or dark web forums. The victim typically has no idea their credentials were taken until they notice suspicious logins or locked accounts.
