BabaCloudLogs Stealer Log Exposes 99,306 Compromised Records

HEROIC detected the BabaCloudLogs stealer log collection being shared across dark web marketplaces and Telegram groups in July 2025. This data set contains 99,306 records of stolen credentials, representing a substantial volume of compromised accounts harvested through widespread infostealer malware infections.

Nearly 100,000 Plaintext Passwords Now in Criminal Hands

All passwords within the BabaCloudLogs collection are stored in plaintext, giving cybercriminals unfettered access to nearly one hundred thousand accounts. Plaintext credentials are the most dangerous form of password exposure because they eliminate every layer of protection that responsible services implement. Attackers can use each password as-is, instantly attempting to gain access to the corresponding account and any other service where the victim may have reused the same password.

What Was Exposed

• Email Addresses — tens of thousands of email accounts serving as usernames across various platforms
• Plaintext Passwords — completely unprotected credentials that attackers can use without modification
• URLs — login endpoints and web services revealing where each credential was captured

How Credential Stuffing Exploits Breaches of This Scale

With 99,306 credential pairs available, threat actors can mount aggressive credential stuffing operations targeting high-value services. Automated tools rapidly test each stolen email and password combination against online banking, email providers, e-commerce platforms, and cloud services. The mathematical reality of password reuse means that even a modest success rate across 99,306 credentials translates to thousands of newly compromised accounts, each one a potential gateway to financial loss or identity theft.

BabaCloudLogs: Tracing the Infostealer Malware Source

The BabaCloudLogs data set originates from infostealer malware campaigns that infected devices across multiple regions. These malware strains are typically distributed through underground malware-as-a-service platforms, where even low-skilled attackers can deploy sophisticated credential theft tools. Once a device is infected, the malware harvests all stored browser passwords, email client credentials, FTP login data, and session cookies, compiling them into organized log files that are aggregated and sold on dark web forums.
