How the skull_roses Stealer Log Malware Led to 40,562 Stolen Logins

In July 2025, a Telegram user operating under the handle skull_roses distributed a stealer log package that exposed 40,562 records containing email addresses, plaintext passwords, and URLs captured from infected U.S. devices. HEROIC analysts have verified the breach and confirmed the data is actively being shared within criminal communities. Many of the 40,562 victims still do not know their credentials were stolen because this type of attack leaves no visible trace on the services they use. If your email address was in this collection, your passwords may already be in circulaton among attackers looking for easy account takeovers.

Why This Is Dangerous

Stealer log data is uniquely dangerous because it bypasses corporate security entirely -- the malware targets your personal device, not a company's servers. The plaintext passwords in this breach require zero effort to use, and the URLs bundled into each record tell attackers precisely where to try them. Victims who rely on password reuse across multiple services face significant risk of cascading account compromises spanning banking, email, and e-commerce platforms in rapid succession.

What Was Exposed

• Email Addresses -- The primary identifier used to access most online accounts, now available to criminals for login attempts, phishing campaigns, and identity-based fraud.
• Plaintext Passwords -- Passwords captured in unencrypted form directly from infected devices, usable immediately by any attacker without decryption or cracking tools.
• URLs -- The exact website addresses where credentials were harvested, giving criminals a precise map of which accounts each victim uses and where to attempt unauthorised access first.

Why This Matters

When criminals acquire a stealer log like skull_roses, their standard workflow begins with automated credential stuffing -- software that tests stolen email and password pairs against hundreds of popular platforms simultaneously. Services targeted typically include online banking portals, email providers like Gmail and Outlook, major retailers, and cloud storage. A single compromised record can unlock multiple accounts if the victim reused passwords, leading to financial theft, identity fraud, and account lockouts that can take weeks to resolve.

How Stealer Log Works

A stealer log is a file produced by malicious software running covertly on a victim's device, recording passwords as they are entered or extracting them from browser storage and autofill databases. The malware is commonly deliverd through game cracks, fake software downloads, or phishing emails -- and once installed it silently sends harvested data to criminal-controlled servers or Telegram channels. The skull_roses collection is one of thousands of such packages distributed and sold by threat actors every month. Because the theft happens on the victim's own machine rather than inside a company's network, affected users almost never receive any official notification or alert from their service providers.
