How BabaCloudLogs Malware Leaked 49,117 Passwords Online

In August 2025, HEROIC analysts identified a stealer log file circulating on Telegram, uploaded by a user tracked as "BabaCloudLogs." The file, labeled 555 Cloud Logs 29.06.2025, contained 49,117 records harvested directly from infected devices. Each record paired an email address with a plaintext password and the website URL where that password was used.

How This Stealer Log Was Discovered

Unlike a traditional corporate data breach, this leak did not come from a hacked company database. It came from malware. Info-stealing malware quietly infects a person's computer, often through a cracked software download or a malicious email attachment, then scrapes saved passwords, browser cookies, and autofill data straight from the device.

Once collected, that stolen data gets packaged into a "log" and sold or given away in Telegram channels that specialize in this kind of underground trading. This particular log was uploaded on June 29, 2025, and picked up by HEROIC's monitoring systems shortly after, giving a small window into how quickly this stolen information can begin circulating.

Why This Is Dangerous

Because the passwords in this log are stored in plaintext, no cracking or decryption is needed. An attacker can simply copy and paste the email and password pair directly into the matching login page. This makes stealer logs some of the most immediately useable stolen data on the dark web, more dangerous in some ways than an encrypted password database.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated login URLs

Why This Matters

Because each record links a real email address to its exact password and the site it unlocks, this data is ready-made for account takeover. If any of these credentials were reused across multiple accounts, attackers can attempt credential stuffing against banking, email, and shopping sites in seconds. From there, identity theft and financial fraud often follow quickly, since a compromised email account can be used to reset passwords on nearly everything else tied to it.

How Stealer Logs Work

Stealer malware is designed to run silently in the background. Once it infects a device, it targets the password manager built into web browsers, along with saved session cookies and autofill fields. It packages everything it finds, endpoints, usernames, passwords, and API hosts, into a single log file.

These logs are then uploaded in bulk to Telegram channels, where thousands of other criminals can download and search them for valuable accounts. This is a suprisingly common and low-effort way for attackers to harvest fresh, working credentials at scale, since the victim entered the password themselves just before it was stolen.
