Inside Bugatti_Cloud: How Infostealer Malware Harvested 7,428 Passwords

HEROIC analysts confirmed the Bugatti_Cloud (Bugatti_Man 13.08.part22) stealer log as a verified breach, with 7,428 records exposed after the file was uploaded to Telegram in August 2023. The log contains email addresses, plaintext passwords, and URLs harvested from infected devices through a systematic infostealer campaign. Understanding how these logs are built helps explain why the data inside them is so dangerous, and why the threat persists long after the initial upload.

Why the Bugatti_Cloud Stealer Log Is Dangerous

Every record in this log was taken from a real device without the user's knowledge. The passwords are stored in plaintext, which removes any barrier between the attacker and account access. Combined with the email address and URL data in the same file, each record gives an attacker a complete picture of that person's online activity and direct login credentials. This log is not a theoretical risk. It is active data that has been circulating since 2023.

What Was Exposed in Bugatti_Cloud

• Email addresses
• Plaintext passwords
• URLs (a direct record of which sites and services each victim was using)

Why This Matters

Credential stuffing is the primary downstream threat from this kind of leak. Attackers load the email and password pairs into automated tools and test them against banks, email services, shopping platforms, and social networks. Because people routinely reuse passwords across accounts, one exposed credential can unlock many doors. The compromise of a single email account puts every connected account at risk, and victims may not notice until unauthorized charges or locked accounts appear.

How Stealer Logs Like Bugatti_Cloud Work

Infostealer malware is designed to run invisibly on a victim's device after being installed through a phishing link, a compromised download, or a fake software update. Once active, it systematically reads saved passwords stored by web browsers, captures login credentials entered in real time, and records the URLs of every site visited. All of this information is structured into a log file and transmitted back to the attacker via an automated channel. The attacker then organizes the data into parts, as seen in the Bugatti_Cloud series, and uploads it to Telegram where it is shared or sold to other criminals. The part22 segment was distributed this way in August 2023 as part of a larger coordinated data release.
