The BR 8.7 Stealer Log Data Quietly Appeared on the Dark Web

HEROIC analysts identified this Stealer log on 28-Feb-2023. The breach exposed 19,683 records, with stolen data including Email Addresses, Plaintext Passwords, and URLs. The source is identified as BR 8.7, uploaded by a Telegram User.

Why This Is Dangerous

The BR 8.7 stealer log contains nearly 20,000 plaintext email and password pairs, likely targeting Brazilian users. These credentials were quietly uploaded to private Telegram channels without any public announcement. People affected by this breach may have no idea their login information is circulating among cybercriminals.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs

Why This Matters

With nearly 20,000 exposed credential pairs, attackers have a substantial list of accounts to test on Brazilian email providers, banking portals, and social media platforms. People who use the same password across multiple services face the greatest risk. Even if a specific account is not immediately compromised, the stolen credentials can be used in future attacks.

How Stealer Logs Work

Stealer logs are created by information-stealing malware that installs itself on infected computers. The malware records login credentials as users visit websites, capturing the email address, password, and URL for each site. These records are compiled into files and distributed through private channels on Telegram and similar platforms.
