The Pegasus Cloud Leak Could Unlock Your Email, Cloud, and Work Accounts

HEROIC analysts found a stealer log file on September 18, 2025, uploaded to a Telegram channel and labeled PegasusCloud. The dump contained 62,092 records tied to users and systems connected to Pegasus Cloud, a cloud infrastructure platform. The exposed data included email addresses, plaintext passwords, and URLs pointing to internal cloud resources. What struck our team was the chain of access this data creates. A single cloud credential doesn't just open one door. It can unlock email accounts, connected services, internal tools, and anything else hosted or accessed through the same platform. The file circulated on Telegram before we identified it and flagged it in our breach database.

Why This Is Dangerous

Cloud platforms act as hubs. Everything runs through them: email, storage, deployment tools, communication platforms, and databases. When an attacker gets a working cloud credential, they don't just gain access to one account. They gain access to an ecosystem. From a single login, they can read emails, access file storage, impersonate users in business tools, and pivot into any service connected through the same identity provider or single sign-on system. Plaintext passwords make this even faster because there's no cracking step involved.

What Was Exposed

• Email addresses linked to Pegasus Cloud accounts
• Plaintext passwords available to anyone with the file
• Cloud resource URLs reveling internal system architecture
• Endpoint and API access details for connected services
• 62,092 total records scraped from compromised machines

Why This Matters

People reuse passwords across platforms. If the password stolen from a Pegasus Cloud account is the same one used for email, banking, or a work system, attackers don't need to hack those platforms separately. They just try the same credentials. This chained risk is why cloud credential leaks are treated as high priority. The Pegasus Cloud PegasusCloud breach shows that even platforms that aren't household names can create serious downstream exposure for thousands of users and the businesses they work for.

How Stealer Logs Harvest Cloud Credentials

Stealer malware is designed to grab credentials from everywhere a user has logged in. It reads saved browser passwords, active session cookies, and typed credentials in real time. Cloud platforms are a primary target because users stay logged in for extended periods and often have broad permissions. Once the stealer captures a cloud session token or password, the attacker can access the account without triggering a new login, bypassing some forms of multi-factor authentication entirely. The harvested files are then distributed on Telegram for other attackers to exploit.

Check If You Are Affected

If you have ever used Pegasus Cloud or any similar cloud platform, and your device has ever been compromised, your credentials and access data may already be in circulation. HEROIC's free breach scanner checks your email against more than 400 billion exposed records, including stealer log collections, to show you what has been leaked and where. One credential in the wrong hands can unlock far more than you expect. Run a free scan now and find out before it's too late.
