SlurmLogs Stealer Log Quietly Exposed 20,898 Stolen Passwords

HEROIC analysts identified a stealer log file uploaded to a Telegram channel on November 29, 2025. The file, known as SlurmLogs, contained 20,898 records pulling together email addresses, plaintext passwords, and the URLs of the websites those credentials were used on.

Why This Is Dangerous

Unlike a typical database leak, a stealer log pairs each stolen password with the exact website it unlocks. That means an attacker does not have to guess where to try a login, the log tells them directly. Combined with the fact that the passwords are already in plaintext, this dataset is essentially a ready-made key ring to real accounts.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites the credentials belong to

Why This Matters

Because each credential in this log is matched to its exact login page, attackers can move straight to account takeover without any trial and error. From there, identity theft and financial fraud follow quickly, especially if any of the URLs point to banking, email, or shopping accounts. This kind of matched data also makes credential stuffing far more efficient than working from a generic email and password list.

How Stealer Logs Work

A stealer log comes from malware installed on a victim's computer, often through a fake download, cracked software, or a malicious email attachment. Once running, the malware quietly scans the browser's saved passwords and autofill data, capturing every website login stored there, then sends that entire collection back to the attacker as a single file. That file, called a log, is exactly what surfaced here on Telegram: a direct export of someone's saved logins, ready to be sold, shared, or used immediately.

Check If You Are Affected

If you save passwords in your browser and are unsure whether your device has ever been infected with stealer malware, it is worth checking now. HEROIC's free breach scanner searches more than 400 billion leaked records, including this dataset, so you can find out quickly and change any passwords that may be exposed.
