Our Analysts Found the CloudyTeamLogs Dump on Private Telegram

HEROIC analysts monitoring dark web and private Telegram channels discovered the CloudyTeamLogs 561count file circulating among threat actors in July 2025. The file, uploaded by a Telegram user operating under the Cloudy Logs Team identity, exposed 26,408 records containing plaintext passwords, email addresses, and URLs. This discovery is part of HEROIC's ongoing surveilance of criminal credential markets, where stealer log files are bought, sold, and traded every day without victims ever knowing their data has been compromised.

Why This Is Dangerous

The CloudyTeamLogs 561count file was not posted on a public forum where it might quickly be flagged and taken down. It circulated in private Telegram channels accessible only to verified criminal actors. This means victims had no chance of being alerted through standard breach notification services. By the time HEROIC's analysts identified and indexed this file, the data had already been in criminal hands for an unspecified period, potentially enabling account takeovers, credential stuffing attacks, and targeted phishing campigns.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (identifying which services were targeted)

Why This Matters

When HEROIC analysts find a file like CloudyTeamLogs 561count in private Telegram channels, it means the data has already passed through multiple hands. Criminal actors share these files to build reputation, attract buyers, or as part of coordinated attack operations. The 26,408 people whose credentials appear in this file may have already experienced unauthorized account access, password changes, or fraudulent transactions -- and many may not yet realize it.

How Stealer Log Breaches Work

The Cloudy Logs Team name suggests an organized operation, not a lone attacker. Groups like this deploy malware at scale -- through phishing kits, malicious browser extensions, and trojanized software downloads -- to harvest credentials from thousands of devices simultaneously. Each infected device reports back to the group's infrastructure, depositing stolen passwords, email addresses, and session tokens into a centralized collection system. These are then sorted, packaged, and distributed as numbered log files -- like the 561count variant discovered by HEROIC analysts -- through private Telegram channels were they command significant prices.
