Inside the Slurm Logs SlurmLogs Breach: How 50,544 Records Were Compromised

In November 2025, a Telegram user uploaded a stealer log collection labeled "Slurm Logs SlurmLogs," exposing 50,544 records pulled from infected devices in the United States. HEROIC analysts reviewing the file found that each record includes an email address, a plaintext password, and a URL identifying the associated service. A dataset over 50,000 records strong is substantial enough to fuel large-scale credential stuffing attempts across many platforms at once.

Why This Is Dangerous

Because every password in this file is stored in plaintext, there is no cracking or decoding step required. Automated tools can load this data directly and begin testing email and password combinations against popular websites and apps such as email providers, banking portals, and corporate logins.

Once shared on a public Telegram channel, a file this size is effectively impossible to remove from circulation. Copies get downloaded and folded into other combo lists that continue to be used in attacks long after the original post.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated service URLs

Why This Matters

Fifty thousand records is a large number by any measure. Even if only a fraction of the passwords in this file are still active, that still represents a meaningful number of accounts that could be accessed right now by anyone who downloaded it. Because stealer logs capture data indiscriminately, the affected individuals likely span a wide range of backgrounds and account types, and password reuse means the damage from a single leaked credential can spread well beyond its original service.

How Stealer Logs Work

Infostealer malware typically arrives through phishing emails, fake software downloads, or malicious browser extensions. Once installed, it runs silently in the background, scanning the infected machine for saved passwords and autofill data, then packages everything it finds into a log file. These logs are either sold on underground markets or, as happened here, released for free on platforms like Telegram to build reputation among criminal communities.

Because this type of theft happens on the victim's own device rather than at any central organization, there is no single company responsible for notifying affected users, and no patch that fixes the exposure after the fact.
