US Stealer Log: HEAVENLOGSCLOUD 1 Exposes 8,857 Credentials

HEROIC analysts identified the 500PCS - HEAVENLOGSCLOUD 1 stealer log circulating on Telegram in March 2023. This release exposed 8,857 records containing email addresses, plaintext passwords, and URLs harvested from infected devices. HEAVENLOGSCLOUD is a prolific actor with at least 82 confirmed releases across multiple countries, including country-coded batches targeting victims globally. Related releases in this series include: ES-SPAIN-248PCS-HEAVENLOGSCLOUD uploaded by a Telegram User, DE-GERMANY-915PCS-HEAVENLOGSCLOUD uploaded by a Telegram User, and CO-COLOMBIA-273PCS-HEAVENLOGSCLOUD uploaded by a Telegram User.

Why This Is Dangerous

Stealer logs capture live credentials at the moment of infection. Because plaintext passwords are recorded directly from the victim's browser or device, there is no hashing barrier to protect them. Attackers can immediately use these credentials to access email inboxes, banking portals, work systems, and any other service where the victim reused the same password. The inclusion of URLs means attackers know exactly which sites each set of credentials belongs to, making targeted account takeover fast and precise.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs (specific sites the victim was logged into)

Why This Matters

Credentials stolen by stealer malware feed directly into criminal ecosystems. Threat actors use them for credential stuffing attacks against major platforms, sell access to corporate networks on dark web marketplaces, drain financial accounts, and commit identity theft. Because the passwords are plaintext, there is no cracking step required. Every record in this dataset represents a real person whose accounts may still be compromised today if passwords have not been changed.

How Stealer Log Breaches Work

Stealer logs are produced by information-stealing malware installed on victims' computers, typically through phishing emails, malicious downloads, or compromised software installers. Once running, the malware silently harvests saved browser credentials, session cookies, and autofill data. It records the username, password, and the URL of each site, then packages everything into a log file that is uploaded to a command-and-control server or shared directly on Telegram channels. Victims rarely know they have been infected. The HEAVENLOGSCLOUD operator organized these logs by country code, suggesting a structured distribution operation selling access by geographic region.
