The InfernoLogsCloud Leak Could Unlock Your Bank, Email, and Social Media

HEROIC analysts identified the InfernoLogsCloud URL LOG PASS FREE200 stealer log after it appeared in a private Telegram channel in October 2025. A threat actor uploaded the file publicly, exposing 18,913,713 records containing email addresses, plaintext passwords, and the URLs of the sites those credentials belong to. This is not a single compromized website. It is a harvested collection pulled from thousands of individual devices by malware before it was packaged and released for free.

Why InfernoLogsCloud Credentials Are a Direct Path Into Your Accounts

Unlike a standard database leak, this breach comes with everything an attacker needs in one place: the website, the username, and the password. There is no guessing required. If your email and password for any site appear in this log, someone already has the exact login string to type into that site today.

Plaintext passwords are especially dangerous because they can be tested immediately across other services. Most people reuse passwords. Attackers know this, and they use automated tools to try each stolen credential against banking portals, email providers, and social media platforms within minutes of obtaining a file like this one.

What the InfernoLogsCloud Stealer Log Exposed

• Email addresses tied to active accounts
• Plaintext passwords stored or typed on infected devices
• URLs of the specific websites where those credentials were used
• API endpoints and host identifiers from browser sessions

Because the data includes the URL alongside each credential pair, attackers can see exactly which service to target. There is no need to run a credential stuffing campaign across hundreds of sites when the log already tells them where each password works.

Why 18 Million Stolen Credentials Create Lasting Risk

Stealer log files circulate for months or years after they are first published. This file was recieved by the threat community in October 2025 and is still available. Anyone who downloaded it can use it at any time. Even if you changed your password the day the breach occured, the old credential may still open doors on sites you forgot you had an account with.

The scale also matters. With nearly 19 million records, this file is large enough to contain credentials from thousands of different websites across banking, healthcare, retail, and social platforms. The risk extends beyond the obvious accounts. Forgotten subscriptions, old forum logins, and secondary email accounts are all potential entry points for attackers practicing credential stuffing or account takeover.

How InfernoLogs-Style Stealer Malware Harvests Your Passwords

Stealer logs are produced by a specific category of malware designed to silently extract saved credentials from infected computers. When a device is compromized, the malware scans the browser's password manager, active sessions, and stored cookies. It packages everything it finds into a structured log file, then uploads that file to a command-and-control server.

The infection can arrive through a phishing email, a malicious download disguised as software, or a compromised advertisement. The user often sees no sign that anything has happened. The malware runs quietly, collects what it needs, and exits. The resulting log is then sold or, as in this case, shared freely in Telegram channels to build a threat actor's reputation in underground communities.

What makes stealer logs seperate from ordinary database dumps is that the data is fresh and verified. It was pulled directly from the user's device at the moment of infection, not extracted from a company's old backup. Every credential in the log was working at the time it was stolen.
