38,921 Accounts Exposed in a wlfrcloud Telegram Stealer Log

HEROIC found: On February 20, 2024, a Telegram user uploaded a stealer log through wlfrcloud, exposing 38,921 records containing email addresses, plaintext passwords, and URLs from compromised endpoints and services.

Why the wlfrcloud Breach Is Dangerous

wlfrcloud is a Telegram-based stealer log channel that aggregates and distributes credentials stolen from malware-infected devices. This dataset contains nearly 39,000 accounts worth of active plaintext passwords linked to real service URLs, giving attackers a ready supply of working credentials for immediate account takeover without any additional processing or cracking.

What Was Exposed in the wlfrcloud Leak

• Email addresses
• Plaintext passwords
• URLs associated with compromised accounts and services

Why This wlfrcloud Data Puts You at Risk

Stealer log data captured from infected devices reflects real, active logins — not old or recycled credentials. Cybercriminals deploy these email-password pairs in automated credential stuffing tools within hours of a new Telegram upload, testing them against email providers, financial institutions, and social platforms simultaneously. The included URL data narrows the attack surface, letting criminals target accounts at the exact services each victim was using.

How Stealer Logs Work

Infostealer malware infects devices through phishing emails, malicious downloads, or compromised software. Once active, it silently harvests saved passwords, browser cookies, and session tokens. The collected data is packaged into stealer log files and distributed through Telegram channels, where cybercriminals purchase or trade them for use in account takeover attacks.
