Inside DVDCLOUDfree Stealer Logs: 7,510 Passwords Harvested

HEROIC's threat research team identified a stealer log archive labeled "DVDCLOUDfree" circulating on Telegram that exposes 7,510 compromised records. Originally collected in March 2024, this dataset contains credentials harvested by infostealer malware—plaintext passwords alongside email addresses and the specific URLs where victims authenticated.

The Technical Reality of Plaintext Password Exposure

Every credential in this DVDCLOUDfree dump is stored in plaintext, meaning the actual password strings are fully visible without any encoding, hashing, or encryption layer. From a technical standpoint, this eliminates the computational barrier that normally slows down attackers. These 7,510 passwords can be loaded directly into credential stuffing tools and executed against target services within seconds.

What Was Exposed

• Email Addresses – Primary authentication identifiers across web services
• Plaintext Passwords – Raw credential strings extracted directly from browser storage
• URLs – The exact endpoints and login pages where credentials were captured

Credential Stuffing at Scale

Armed with 7,510 email-password pairs and the URLs they belong to, attackers can run automated credential stuffing campaigns against any platform. Tools like OpenBullet and SentryMBA test thousands of login combinations per minute. Since users frequently reuse passwords across services, a single valid pair from this dump can unlock accounts on email platforms, financial portals, and enterprise tools.

How Infostealers Extract Browser Credentials

The malware behind these logs—families like Redline, Vidar, and Stealc—targets the credential storage mechanisms built into web browsers. When a browser saves a password, it is stored in a local database that the malware can decrypt using the victim's own system keys. The extracted credentials, along with cookies and autofill data, are packaged into structured log files and uploaded to command-and-control servers before being distributed on Telegram.

Check If Your Credentials Were Exposed

HEROIC's breach scanner indexes more than 400 billion compromised records from stealer logs, data breaches, and paste sites. Search your email address or domain to find out if your credentials were captured in the DVDCLOUDfree dump or any other known leak. Early detection lets you rotate compromised passwords and enable two-factor authentication before attackers can act.
