In June 2025, a Telegram user uploaded a stealer log file known as Cheese_vip 626count, exposing 36,133 records stolen from real devices. The dump contained email adresses, plaintext passwords, and URLs harvested by malware running silently on infected machines. If you have ever reused a password across sites, this breach could have unlocked far more than one account.


Why This Is Dangerous

Stealer log breaches are among the most severe types of credential exposures because the data is harvested directly from victims' devices. Unlike database breaches where passwords may be hashed, stealer logs capture credentials in plaintext at the moment of entry. This means attackers recieve passwords exactly as you typed them, ready to use immediately across banking, email, and social media accounts. The Cheese_vip dump was distributed freely on Telegram, placing 36,133 sets of credentials in the hands of thousands of threat actors simultaneously.


What Was Exposed

  • Email Addresses
  • Plaintext Passwords
  • URLs (revealing which sites and services were targeted)

Why This Matters

Stealer logs do not discriminate. Whether you visited a shopping site, a work portal, or a personal banking page, the malware captured every credential it encountered. The URLs included in this dump reveal the exact sites targeted, allowing attackers to launch highly targeted phishing and account takeover campaigns. With 36,133 records distributed openly on Telegram, this data has almost certainly been used in automated credential stuffing attacks against hundreds of platforms.


How Stealer Log Breaches Work

Stealer malware, such as the type behind the Cheese_vip log, is typically delivered through phishing emails, malicious downloads, or cracked software. Once installed on a device, it silently records keystrokes, captures autofill data, and harvests stored passwords from browsers and applications. The collected data is then packaged into log files and sold or shared on dark web forums and Telegram channels. Victims often have no idea their device was ever compromised. A single infection can expose credentials for dozens of accounts in one sweep.
