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

In November 2025, a Telegram user published a stealer log collection under the name "Slurm Logs SlurmLogs," exposing 50,544 records from compromised endpoints in the United States. The dataset includes email adresses, plaintext passwords, and API host information pulled directly off infected machines. For anyone whose device was running infostealer malware at the time, their credentials may now be in the hands of whoever downloads this file.

Why This Is Dangerous

With over 50,000 records, this is a substantial dump. The combination of email addresses and plaintext passwords is essentially a ready-to-use kit for credential stuffing, where automated tools attempt those exact username and password pairs against popular websites and apps. Services like Gmail, banking portals, and corporate VPNs are common targets.

What makes this worse than a typical breach is the API host data. That type of information doesn't just expose individual accounts, it potentially gives attackers a foothold into backend systems, internal tools, and cloud infrastructure. A developer or IT worker whose device was infected could have inadvertently handed over keys to much more than a personal account.

Because the file was shared on a public Telegram channel, it's effectively impossible to remove from circulation. The data has likely been downloaded, copied, and added to various combolists that will be used in attacks for months or even years.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of accessed websites and services
• API host credentials
• Endpoint device information
• Browser-stored login data
• Session tokens or cookies from infected machines
• Application credentials harvested from device storage

Why This Matters

Fifty thousand records is not a small number. Even if only a fraction of those passwords are still active, that's potentially thousands of accounts that can be accessed right now by anyone who downloaded this log. And because stealer logs capture data indiscriminately, the affected users may come from a wide range of industries and roles.

Organizations should be particularly concerned if any employees had company credentials stored on personal or unmanaged devices. This kind of leak can serve as an entry point for ransomware attacks, data theft, or business email compromise. It's the sort of breach that occured quietly but can have loud consequences down the line.

How Stealer Log Works

Infostealer malware typically arrives via phishing emails, fake software downloads, or malicious browser extensions. Once installed, it runs silently in the background, scanning the infected machine for saved passwords, browser cookies, autofill data, and credentials stored by applications like email clients or remote access tools.

The harvested data is then exfiltrated to a server controlled by the attacker and bundled into a log file. These logs are either sold on dark web markets or, increasingly, dumped for free on platforms like Telegram to build reputation or share with a broader audience of criminals. Either way, once the data is out there it's essentially public.

What separates this attack type from a server breach is that the security failure happened on the victim's device, not at any central organization. That means there's no company to hold accountable and no single patch that fixes the problem. The only real defense is keeping devices clean and avoiding credential reuse.
