The 860K URL LOG PASS Dump: 800K Stolen Login Credentials Hit the Dark Web

HEROIC analysts identified a stealer log file uploaded to a private Telegram channel in November 2025. The archive contained 800,427 records tied to real user sessions, harvested silently from infected devices. Exposed data includes email addresses, plaintext passwords, and URLs representing active login sessions at the time of infection. This is not an old breach resurfacing -- this data was collected recently, making it highly actionable for attackers.

Why This Is Dangerous

Stealer log files are different from typical database breaches. The passwords in this file are plaintext -- meaning they were captured exactly as the user typed them, before any encryption could protect them. An attacker holding this file knows your email address, the exact password you use, and the specific website you were logged into. They don't need to crack anything. They can walk straight into your accounts. And because most people reuse passwords across multiple sites, a single compromised credential can unlock email inboxes, social media profiles, banking portals, and cloud storage all at once.

What the 860K URL LOG PASS Stealer Log Exposed

• Email addresses linked to real user accounts
• Plaintext passwords captured during active sessions
• URLs showing which websites users were logged into at the time of infection

The combination of URL plus email plus plaintext password is one of the most complete credential packages a cybercriminal can posess. It tells them exactly where to use each stolen login.

Why This Matters for Account Security

When stealer logs hit private Telegram channels, they move fast. Threat actors use the data immediately for credential stuffing -- automated attacks that try stolen username and password combinations across hundreds of popular websites. If you reuse passwords, one compromised login from this file could lead to account takeover across your entire digital life. Researchers have linked this type of data to identity theft, fraudulent purchases, SIM swapping, and targeted phishing campaigns against the original victim's contacts. The presence of captured URLs also means attackers know exactly which platforms to target first.

How Stealer Log Malware Works

Stealer logs are produced by a category of malware known as information stealers. These programs are typically delivered through phishing emails, fake software downloads, malicious browser extentions, or cracked application installers. Once installed on a device, the malware runs quietly in the background. It monitors browser activity, captures keystrokes, and extracts saved credentials directly from browser storage. The harvested data -- emails, passwords, cookies, and visited URLs -- is bundled into a log file and sent back to the attacker. These logs are then sold or freely distributed on dark web forums and private Telegram channels, as happened in this case. The infected user often has no idea anything went wrong.

Check If Your Accounts Were Exposed

Because this file circulated in private Telegram channels, it may not appear in smaller breach databases. HEROIC's breach scanner searches across more than 400 billion exposed records, including stealer log collections that most tools never index. If your email address appeared in this file -- or in thousands of other breaches like it -- you'll find out immediately.
