Endpoint Users Targeted in the 43,382 Record Slurm Private Logs ArhontCorp Breach

HEROIC analysts flagged the Slurm Private Logs TG ArhontCorp dataset when it appeared on a public Telegram channel in January 2026. The log contained 43,382 records exfiltrated by infostealer malware from compromised endpoints. Each record included an email address, a plaintext password, and URLs representing the services the victim accessed. The dataset was uploaded under the identity ArhontCorp and was immediately accessible to thousands of threat actors monitoring Telegram for fresh credential dumps.

Why This Stealer Log Is Especially Dangerous

With 43,382 records containing plaintext passwords, the Slurm Private Logs ArhontCorp breach represents a large-scale credential exposure that requires no cracking or decryption. Attackers who recieve these logs can immediately begin testing the email and password combinations against popular services. The inclusion of API host URLs in each record adds another layer of risk, as these URLs reveal exactly which platforms and internal systems the compromised users were accessing at the time of infection.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (targeted service endpoints and API hosts)

Why This Matters

This breach occured in January 2026 and was distributed immediately through Telegram, one of the primary platforms threat actors use to share and sell stolen credential data. Because the passwords are plaintext, every account tied to a reused password is now compromised across every service where that password was used. Forty-three thousand exposed records is a large enough pool that credential stuffing campaigns built on this data can generate significant unauthorized access at scale. If your email appears in this dataset and you have not rotated your passwords, you remain exposed today.

How Stealer Log Attacks Work

Infostealer malware spreads through phishing campaigns, malicious browser extensions, cracked software, and trojanized installers. Once executed on a victim's machine, the malware operates silently, capturing credentials stored in browsers, keylogging active sessions, and harvesting cookies that can bypass multi-factor authentication. The captured data is organized into a structured log file and sent to an attacker-controlled server. These logs are then packaged into named collections and distributed on Telegram channels, where they are sold or shared freely. The seperate steps of infection, exfiltration, and distribution make attribution difficult and give attackers days or weeks before victims are aware their data has been stolen.
