8,742 United States Accounts Caught in the Bugatti_Cloud Stealer Log

HEROIC analysts identified and verified the Bugatti_Cloud (Bugatti_Man 13.08.part01) stealer log, which was uploaded to Telegram in August 2023. This first installment of the Bugatti_Cloud series exposed 8,742 records, including email addresses, plaintext passwords, and URLs harvested from compromised devices. The data was collected by infostealer malware operating invisibly on victim machines, with users in the United States making up a significant share of those affected. The credentials in this log remain in active circulation across underground markets.

Why the Bugatti_Cloud Stealer Log Is Dangerous

With plaintext passwords, email addresses, and a clear map of which services victims were using, this log provides everything an attacker needs to begin compromising accounts with no additional effort. Attackers can test the credentials against financial platforms, email providers, and social networks immediately. The United States concentration in this dataset means attackers can target accounts at major US banks, retail sites, and telecommunications providers with high precision.

What Was Exposed in Bugatti_Cloud

• Email addresses
• Plaintext passwords
• URLs (identifying the specific services each victim was logged into)

Why This Matters

A plaintext password combined with an email address is all an attacker needs for a credential stuffing attack. Automated tools test the same login pair across dozens of services in seconds. Because password reuse remains widespread, the damage from a single leaked credential can quickly spread to banking accounts, streaming services, email, and beyond. Once an email account is compromised, password resets on every linked account follow, opening the door to identity theft and financial fraud.

How Stealer Logs Like Bugatti_Cloud Work

Infostealer malware infects devices through phishing emails, fake software installers, and malicious browser extensions. It runs silently after installation, extracting saved passwords from browsers, capturing credentials typed into login forms, and logging the URLs of sites visited. All of this is packaged into a structured log and transmitted to the attacker's infrastructure. The Bugatti_Cloud log was then segmented into parts and uploaded to a Telegram channel in August 2023, where it became available to other threat actors.
