Logs_24 June Telegram Leak Exposed 823 U.S. Stealer Log Records

In June 2025, a threat actor operating on Telegram quietly uploaded a stealer log file containing 823 records harvested from compromised U.S. endpoints. The data included raw email addresses, plaintext passwords, and full URLs, meaning real accounts were actively exposed with no encryption or hashing protecting them. Stealer logs like this one are among the most dangrous categories of breach data because the credentials they contain are often fresh and immediately usable by attackers.

Why This Is Dangerous

Unlike traditional database breaches, stealer logs are generated by malware running directly on a victim's device. That means the passwords captured are the actual, in-use credentials at the time of infection, not old or rotated ones. The 823 accounts exposed in this Telegram leak were likely still active when the data was published, making credential stuffing and account takeover attacks straightforward for anyone who downloaded the file. Because the passwords are in plaintext, there is zero barrier to misuse.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (endpoint and API host addresses)

Why This Matters

Stealer log dumps shared on Telegram channels spread extreamly fast. Within hours of being posted, files like this are downloaded, parsed, and weaponized by multiple threat actors across various cybercrime forums. The inclusion of endpoint URLs alongside credentials means attackers know exactly which services to target. For businesses, exposed API host addresses can signal internal infrastructure, elevating the risk beyond simple account compromise into potential network intrusion.

How Stealer Log Breaches Work

Stealer malware, such as Redline, Raccoon, or Vidar, infects a device through phishing emails, malicous downloads, or compromised software installers. Once installed, it silently harvests saved browser credentials, session cookies, and form autofill data. That harvested data is packaged into log files and sent to command-and-control servers or uploaded directly to Telegram channels where cybercriminals buy, sell, and share it freely. Victims often have no idea their credentials have been stolen until they notice unauthorized account activity.
