Inside BabaCloudLogs 303: How Infostealer Malware Stole 19,963 Passwords

HEROIC analysts flagged a stealer log upload on July 6, 2025, traced to a Telegram channel operating under the name "BabaCloudLogs." This was the 303rd batch in a series of credential dumps posted by this channel. The file contained 19,963 records of stolen account data, each row representing a real person whose computer had previously been infected with credential-stealing malware. The data was made freely available to anyone following the channel.

Plaintext passwords are ready to use the moment a criminal downloads the file. There is no extra step. The attacker already knows which website each password was used on because the URL is included in the log. That means they can go directly to your bank, your email, or your employer's portal and attempt to log in. If your password was captured and you have not changed it, that window is still open right now.

What Was Exposed in the BabaCloudLogs 303 Dump

• Email addresses
• Plaintext passwords
• Login URLs and API endpoints associated with each credential

Why This Matters to Real People

A stealer log is not just a list of passwords. It is a map. Each record connects an email address to a real password to a specific website, giving an attacker a precise playbook for breaking into that person's accounts. Credential stuffing software can work through all 19,963 combinations automatically, testing each one against popular services within hours.

Account takeover is the most immediate risk. Once inside an email account, an attacker can request password resets for every other service linked to that address. From there, the path to identity theft is short: new credit cards, loan applications, and fraudulent purchases can all be initiated using nothing more than the access gained through a single compromised email account.

Financial fraud folows closely behind. Online banking credentials, payment platform logins, and e-commerce accounts with stored cards are all high-value targets. Victims frequently discover the damage only after seeing unauthorised transactions or being notified of accounts opened in their name.

Inside BabaCloudLogs: How This Stealer Log Operation Works

BabaCloudLogs is the name of a Telegram channel that regularly publishes batches of credential logs harvested by infostealer malware. The numbering system (303, 325, and so on) indicates that this is part of an ongoing, organised operation rather than a one-off event. Whoever runs this channel has access to a steady supply of newly stolen credentials.

The underlying malware typically infects computers through phishing emails, software cracks, or fake browser extensions. Once running, it silently copies saved passwords, monitors what the user types, and uploads the results to an attacker-controlled server. The logs are then compiled and posted to channels like BabaCloudLogs, where thousands of subscribers can download them instantly.

Cloud logs, specifically, refer to credentials captured from cloud-based services, often including work accounts, SaaS platforms, and API keys. This makes BabaCloudLogs batches particulary valuable to attackers targeting business environments, not just personal accounts.

Check If Your Information Was Exposed

HEROIC's free breach scanner covers more than 400 billion leaked records and is updated regularly with new stealer log batches including BabaCloudLogs dumps. Search your email address now to find out if your credentials are in this dataset or any other known leak.

If you are affected, change your passwords immediately, starting with email and any financial accounts. Enable two-factor authentication on all important accounts. Do not reuse passwords across services.
