If You Reuse Passwords, the BabaCloudLogs Leak Should Worry You

HEROIC analysts spotted a stealer log named BabaCloudLogs uploaded to a Telegram channel on September 15, 2025. The file contained 8,169 records, each pairing an email address with a plaintext password and the URL that password unlocks. There was no encryption standing between whoever downloaded this file and the accounts inside it.

Why This Is Dangerous

Because the passwords are stored in plaintext, anyone who has this file can read them directly and start logging into accounts immediately. Paired with the URL for each login, an attacker knows exactly which service every password belongs to, removing the guesswork that normally slows down account takeover attempts.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters

Leaks like this one are the raw material for credential stuffing, where attackers take stolen email and password combinations and try them across banking sites, email providers, and online stores. If you reuse a password across more than one account, a single stealer log like BabaCloudLogs is enough to trigger account takeover, identity theft, or financial fraud far beyond the original 8,169 records.

How Stealer Logs Work

A stealer log is produced by infostealer malware that infects a device through a fake download, pirated software, or a phishing link. Once installed, it quietly copies saved passwords, autofill data, and browsing history from the device, then bundles it into a file for the attacker. In this case, that file was shared on Telegram under the name BabaCloudLogs, making 8,169 sets of credentials instantly available to anyone in the channel.
