Beware: baset_cloud 359count Just Dumped 18,866 Accounts on Telegram

HEROIC analysts flagged the baset_cloud 359count stealer log after it was uploaded to Telegram in July 2025. The dataset exposes 18,866 records containing email addresses, plaintext passwords, and URLs harvested directly from infected devices -- making every victim immediately vulnerable to account takeover without any further work by an attacker.

Who Is Targeted by This Stealer Log

Stealer logs distributed via Telegram are not indiscriminate. The baset_cloud 359count dataset targets everyday users whose devices were infected with credential-harvesting malware. These individuals may have no idea their credentials were captured. With 18,866 exposed records and plaintext passwords, every person in this dump is a direct target for automated login attacks the moment a threat actor downloads the file.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (services accessed at time of infection)

Why This Matters

Plaintext passwords combined with emails and URLs give attackers a ready-made attack kit. There is no need to crack hashes or guess credentials. This data enables:

• Credential stuffing -- automated login attempts across email, banking, and social platforms
• Account takeover -- direct access to any service where the victim reused the same password
• Identity theft -- personal information harvested from compromised accounts enables further fraud
• Financial fraud -- access to payment services and saved card details

How Stealer Logs Work

Stealer malware infects devices through phishing links, trojanized software downloads, or malicious browser extensions. Once running, it extracts saved passwords from browsers, captures active session cookies, logs keystrokes, and records the URLs of every site the victim visits. All of this data is packaged into a log file and sent to the attacker -- or, as with baset_cloud 359count, uploaded to a Telegram channel for free distribution among the cybercriminal community. The 18,866 victims in this log had no warning that their credentials were being collected.
