53,099 Plaintext Passwords From CaptainBayOwner Leaked on Telegram

In June 2025, a Telegram user uploaded a stealer log file containing 53,099 records tied to CaptainBayOwner endpoints. The data includes plaintext passwords, email adresses, and URLs harvested directly from infected devices. This type of breach is particularly dangerous because the credentials are not hashed or encrypted -- they are ready to use the moment they land in the wrong hands.

Why This Is Dangerous

Stealer logs are among the most actionable types of breach data available on the dark web. Unlike database dumps where passwords may be hashed, stealer logs capture credentials in real time as victims type them. The data exposed here includes plaintext passwords, which means anyone who obtains this file can immediately attempt to log in to the accounts listed. With 53,099 records exposed, the scale is significant enough to fuel widespread credential stuffing attacks across banking, email, and social media platforms.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (the specific sites where credentials were captured)

Why This Matters

Many people recieve news of a breach and assume they are safe if they have not noticed any suspicious activity. That assumption is dangerous. Stealer log data is often sold or traded multiple times before it is used, meaning your credentials could be circulating for months before an attack occured. If your email and password appear in this dataset, any account where you reuse that password is at risk -- not just the original site where the credential was captured.

How Stealer Log Attacks Work

Stealer malware is typically delivered through phishing emails, malicious downloads, or compromised software installers. Once installed on a victim's device, it silently records keystrokes and harvests stored credentials from browsers and applications. The collected data is then packaged into log files and uploaded to dark web forums or Telegram channels, where cybercriminals buy and trade them. The CaptainBayOwner 754count upload followed this exact pattern -- a Telegram user distributed the log file, making 53,099 sets of credentials available to anyone in that channel.

Check If You Are Affected

HEROIC offers a free scanner that searches across more than 400 billion records to tell you whether your email address appears in this breach or thousands of others. If your data was captured by this stealer log, finding out now gives you the chance to change your passwords before someone else uses them. The seperate question of whether your other accounts share that password is equally important -- credential stuffing works precisely because people reuse passwords across sites.
