82,721 Plaintext Passwords From ArhontCorp Part 3 Dumped on Telegram

HEROIC uncovered a large-scale stealer log dump labeled ArhontCorp Part 3 being distributed on Telegram in July 2026. With 82,721 compromised records, this is a significant credential exposure. Every password in the dataset is stored in plaintext, meaning attackers can use them instantly without any decryption.

Unencrypted Passwords Put Thousands at Risk

Plaintext password storage represents the worst-case scenario for credential exposure. There are no cryptographic protections to slow attackers down. Each password in this dump is a direct copy of what the victim typed, ready to be pasted into a login form. At this scale — over 82,000 records — the potential for widespread account compromise is enormous.

What Was Exposed

• Email Addresses — used to locate victims' accounts across the internet
• Plaintext Passwords — enabling instant unauthorized access with no cracking needed
• URLs — documenting which websites and platforms were targeted by the malware

The Credential Stuffing Pipeline

A dump of this size is a goldmine for credential stuffing operations. Attackers feed the stolen email-password pairs into automated tools that blast login attempts across banking sites, email providers, e-commerce platforms, and corporate systems. Because the majority of internet users reuse passwords, even a modest success rate across 82,721 credentials translates to thousands of compromised accounts.

Where Stealer Log Data Comes From

Stealer logs are the output of infostealer malware infections. These trojans spread through phishing campaigns, malicious software bundles, and exploit kits. Once on a victim's device, they silently capture browser-saved passwords, session cookies, form data, and system information. The resulting logs are organized into easily searchable files and distributed through underground Telegram groups, making them accessible to criminals worldwide.

Check If Your Credentials Were Exposed

With over 82,000 records in this single breach, the odds of being affected are real. HEROIC's breach monitoring platform indexes more than 400 billion compromised records from data breaches and stealer logs globally. Search your email address or domain using HEROIC's breach scanner to determine if your credentials appear in this dataset, and take immediate steps to secure any exposed accounts.
