BabaCloudLogs 335 Leaked 16,239 Cloud Credentials on Telegram

HEROIC analysts discovered a stealer log file posted to a public Telegram channel on May 18, 2025, by an anonymous user operating under the BabaCloudLogs handle. The upload contained 16,239 records sourced from compromised endpoint devices, each record pairing an email address with a plaintext password and the URL of the service where those credentials were used. The log structure matches known infostealer malware output, indicating the data was quietly harvested from infected machines before being bundled and distributed on Telegram.

Why This Is Dangerous

Every record in this file is a ready-made key to someone's account. The URLs tell an attacker exactly which service to target, the email is the username, and the password is already in plaintext with no decryption required. Cloud service credentials are especialy valuable because a single login can expose file storage, email archives, internal documents, and billing information all at once. Attackers routinely automate this process, testing thousands of credential pairs per hour across dozens of platforms simultaniously.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (login destinations and cloud service endpoints)

Why This Matters

Cloud credential theft creates a cascading risk. Once inside a cloud account, an attacker can:

• Access stored files and backups containing business data, financial records, or private communications
• Conduct credential stuffing against other services using the same email and password combination
• Hijack email accounts to reset passwords on banking, payroll, or e-commerce platforms
• Commit financial fraud by using stored payment methods or impersonating the account owner
• Sell verified working logins on dark web markets for repeated exploitation by multiple buyers

How Stealer Logs Work

A stealer log is the output of infostealer malware, a type of program designed to silently collect credentials from an infected computer. The malware typically enters through a phishing link, a fake software installer, or a malicious browser extension. Once running, it scans saved passwords in browsers like Chrome and Firefox, copies session cookies, and records any credentials entered into login forms. All of this is packaged into a structured text file and sent back to the attacker. These logs are then sold in bulk or posted publicly on channels like Telegram, where anyone can download and use the stolen credentials immediately.
