Logs_9 March Stealer Log Leaked 89,957 Plaintext Passwords Online

HEROIC analysts found a stealer log file, labeled Logs_9 March_processed, uploaded by an anonymous user to a public Telegram channel on March 9, 2025. The file contains 89,957 records, each pairing an email address with a plaintext password and the URL of the site or API endpoint the credential was used on. This data was harvested directly from infected devices rather than stolen from a single company's database.

Why This Is Dangerous

These credentials are stored in plaintext, which means they are ready to use the instant someone downloads the file, with no cracking or decryption needed. Each record also lists the exact URL the login belongs to, so an attacker knows precisely which account to target rather than having to guess, making this dataset far more efficient for account takeover than a typical password leak.

What Was Exposed in This Stealer Log

• Email addresses
• Plaintext passwords
• Associated login URLs

Why This Matters

With 89,957 records in this single file, the potential for damage is significant. Because each password is paired with the exact site it unlocks, attackers can move straight to logging into banking portals, email accounts, or work systems without any trial and error. That precision raises the risk of identity theft, financial fraud, and account takeover for anyone whose credentials appear in this log, especially since the passwords are already usable in their raw form.

How This Stealer Log Was Created

A stealer log comes from information-stealing malware that infects a device, often delivered through a malicious download, cracked software, or a phishing link. Once running, the malware quietly collects saved browser passwords, autofill data, and session details, then organizes everything into a log file sorted by the website or service each credential belongs to. That log is then shared or sold, in this case posted for free on a Telegram channel where other criminals can pick through it and pull out accounts worth targeting. The scale of this file, nearly 90,000 records, suggests it was compiled from many infected machines over time rather than a single device.

Check If You Are Affected

Because stealer log data comes from infected devices rather than a single named website, you do not need to recognize this incident by name to be at risk. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including this one, so you can find out what has been exposed and secure your accounts before someone else uses this data against you.
