Inside Bugatti_Cloud Stealer Logs: 3,622 Passwords Harvested

HEROIC's threat intelligence team analyzed the fourth part of the Bugatti_Cloud stealer log series, posted to Telegram in July 2026. This segment contains 3,622 records, each structured with an email address, a plaintext password, and the URL of the targeted service. The Bugatti_Cloud operation releases data in numbered parts, indicating a systematic and ongoing credential harvesting campaign.

Plaintext Passwords Require Zero Cracking Effort

The passwords contained in Bugatti_Cloud Part 04 are stored entirely in plaintext. No cryptographic hashing or encryption was applied to protect them. From a technical standpoint, this means the data requires no preprocessing before exploitation. An attacker can parse the file, extract any email-password pair, and attempt authentication on the corresponding URL or any other service within seconds. The time-to-exploit is effectively zero.

What Was Exposed

• Email Addresses — account login handles used across web services and applications
• Plaintext Passwords — unprocessed credential strings in their original input form
• URLs — target endpoints showing exactly where each credential was harvested

Automated Credential Stuffing Exploits This Data at Scale

Credential stuffing frameworks like OpenBullet and SentryMBA are commonly used to process dumps like Bugatti_Cloud. These tools accept email-password lists and test them against configurable target sites at high speed. The 3,622 pairs in this batch, combined with entries from other Bugatti_Cloud parts, create a sizeable attack surface. Every victim who reused their password on another service becomes a potential secondary compromise.

Bugatti_Cloud: A Technical Look at the Operation

The Bugatti_Cloud operation distributes stealer logs harvested by infostealer malware variants that target browser credential stores, cookie databases, and autofill caches. The malware intercepts credentials as they are saved or entered, then exfiltrates them to collection servers. The aggregated logs are segmented by date and batch number, then distributed through the Bugatti_Cloud Telegram channel. Each part represents a distinct extraction window, with new credentials flowing in continuously as more devices are compromised.

Check If Your Credentials Were Exposed

The Bugatti_Cloud series spans multiple parts, and your credentials could appear in any of them. Use the HEROIC data breach scanner to search across more than 400 billion compromised records and check whether your email or password was included in the Bugatti_Cloud Part 04 dump or any other known breach. If a match is found, change your password immediately, generate unique passwords for all accounts using a password manager, and enable two-factor authentication everywhere it is offered.
