ArhontCloud Leak: 93,100 Logins Added to 400B+ Record Database

On October 19th, 2025, a Telegram user uploaded a stealer log labeled "Slurm Private Logs TG ArhontCloud." HEROIC analysts confirmed the file contained 93,100 records pairing email addresses with plaintext passwords and the URLs each login was captured from, one of the larger stealer log dumps to surface on the platform that month.

Why This Is Dangerous

At more than 93,000 records, this single file gives attackers a large, ready-to-use list of working logins. Every password is stored in plain, readable text and matched to the exact site it unlocks, so no cracking or guessing is needed before an attacker can attempt to log in.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs (the login pages or API hosts tied to each credential)

Why This Matters

A leak of this size gives credential stuffing operations a substantial pool of working logins to test against banking, email, and shopping sites. Because password reuse is common, a single stolen credential from this file can cascade into account takeover, identity theft, or financial fraud across accounts that were never directly attacked.

How Stealer Log Breaches Work

Infostealer malware infects a device, often through a malicious download or cracked software, and silently copies every password, cookie, and autofill entry saved in the browser. Once enough infected devices report back, the results are compiled into a single large log like this ArhontCloud file and distributed through Telegram channels and dark web forums.
