12,121 Accounts Exposed in the Bugatti_Cloud Telegram Stealer Log

In May 2023, a Telegram user distributed a stealer log file labeled Bugatti_Cloud Bugatti_Man 17.05.part038. Security analysts identified 12,121 records in the file, sourced from infected devices and containing email addresses, plaintext passwords, and the URLs of the sites where those credentials were actively being used. While the breach was catalogued under a United States designation, stealer log campaigns are global by nature. Victims can be located anywhere their device was infected, regardless of national borders.

Why This Is Dangerous

A stealer log with plaintext passwords and matching URLs is the most imediately usable form of stolen credential data. There is no decryption step, no cracking required, and no delay. An attacker who downloads this file can start testing credentials against live accounts within the hour. Every email address in this log represents a real person whose password was silently pulled off their device by malware they likely never knew was there.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (the login pages where each credential set was captured)

Why This Matters

The scale of the Bugatti_Cloud Bugatti_Man campaign, spanning dozens of part files and hundreds of thousands of records in total, reflects a well-organized data harvesting operation. Each individual part file, including this one with 12,121 records, contributes to a larger pool that attackers cross-reference to maximize impact. Victims whose credentials appear in multiple part files face compunded risk. For anyone who has ever saved a password in their browser, the threat from stealer logs is very real. Credential stuffing, account takeover, and identity theft are the most comon outcomes.

How Stealer Logs Work

Stealer log malware exploits the convenience features that modern browsers offer. When a browser saves your password, it stores that information locally in a database on your device. Infostealer software targets these databases specifically. Once your device is infected, the malware reads your browser's saved credentials, pairs each one with its associated URL, and packages everything into a structured log file that is transmitted to the attacker. The process is automated and takes only seconds per device. The resulting files are then sorted by country, domain type, or other criteria and distributed through underground marketplaces and Telegram channels. The Bugatti_Cloud Bugatti_Man series is a direct product of this pipeline.
