This breach involves a stealer log file, dubbed "SlurmLogs," uploaded to Telegram. It contains 6,408 records harvested from compromised endpoints. The data includes email addresses, plaintext passwords, and URLs, all seemingly related to Slurm deployments. The fact that passwords were stored in plaintext is a serious security lapse that significantly amplifies the risk associated with this breach.

The log file was identified on March 29, 2025, shortly after it was posted on a Telegram channel known for distributing stealer logs. The file's name, "SlurmLogs," and its contents quickly drew attention. The presence of plaintext passwords, combined with the focus on Slurm-related data, suggested a targeted effort to compromise HPC systems. This is particularly concerning given the sensitivity of the data often processed on such systems, which can include scientific research, financial modeling, and defense-related simulations.

This breach matters to enterprises now because it highlights the ongoing threat posed by stealer logs and the importance of securing HPC environments. The use of plaintext passwords is an egregious security failure that makes it easy for attackers to gain unauthorized access. Furthermore, the targeting of Slurm suggests that attackers are actively seeking to compromise HPC resources for various purposes, including data theft, resource hijacking, and potentially even sabotage.

Security researcher Catalin Cimpanu at The Record has previously reported on the increasing prevalence of stealer logs targeting specific software and platforms, noting that "attackers are increasingly focusing on stealing credentials for specific services, rather than just gathering as much data as possible" (The Record, archived link unavailable). This trend aligns with what we're seeing in the SlurmLogs breach, suggesting a more strategic approach to credential theft.

On BreachForums, users have discussed the potential impact of compromised Slurm credentials, with one user noting, "Access to Slurm can give you access to a ton of compute power. Imagine running password cracking rigs or crypto miners on compromised HPC clusters." This highlights the potential for attackers to exploit compromised Slurm deployments for malicious purposes.
