Researchers Link the Taro Cloud Free Telegram Log to 3,309 Stolen Cloud Credentials

HEROIC analysts identified this file in late October 2023 while monitoring Telegram channels known for distributing compromised credential data. A stealer log posted on October 23, 2023 contained 3,309 records tied to Taro Cloud Free, a cloud services platform. What set this dump apart from the typical broad-spectrum stealer log was its consistent focus on one service. The records included email addresses, plaintext passwords, API host details, and URLs that pointed directly at Taro Cloud infrastructure. The specificity of the data indicated a targeted campaign rather than incidental collection from general device infections.

Why This Is Dangerous

Credentials linked to cloud platforms are among the most dangerous categories of leaked data. Unlike a compromised social media account, a stolen set of cloud credentials can give an attacker access to files, databases, communication systems, and backend services all in one move. The inclusion of API host details in this dump removes the reconnaissance step entirely. Attackers already know where to point their tools. The plaintext nature of the passwords means no additional steps are required. The combination of endpoint data and unencrypted credentials makes this log extremely actionable for anyone who dowloaded it from the Telegram channel.

What Was Exposed

• 3,309 total records
• Email addresses tied to Taro Cloud Free accounts
• Plaintext passwords (no encryption applied)
• API host information for cloud infrastructure access
• URLs associated with active sessions and platform endpoints
• Leak first appeared on Telegram on October 23, 2023

Why This Matters

Stealer log leaks targeting cloud services are particularly concerning for small to medium businesses that rely on affordable cloud platforms. These organizations often have fewer security controls in place, making it less likely they will detect an unauthorized login triggered by a leaked credential. Taro Cloud Free users who have not rotated their passwords since October 2023 remain at active risk. The data may have already passed through multiple hands given how freely these logs circulate across Telegram groups over time.

How Stealer Logs Work

Stealer malware infects a device and immediately begins harvesting stored credentials. It targets browser password managers, saved form data, session cookies, and sometimes even locally stored configuration files. The collected data is compressed into a log file and transmitted back to the attacker, often in real time. The attacker then categorizes the logs by service type or value and distributes them through Telegram channels or underground markets. In the case of the Taro Cloud Free dump, the malware appears to have been deployed on machines that were actively logged in to the platform, capturing live session data alongeside stored passwords.

Check If You Are Affected

If you have ever used Taro Cloud Free, your email address and password may be included in this Telegram stealer log. HEROIC's free breach scanner searches more than 400 billion leaked records from data breaches, stealer logs, and dark web dumps worldwide. A quick check takes less than a minute and can tell you whether your credentials are already circulating and what other data may have been exposed alongside them.
