The DAISY_CLOUD Telegram Dump: 6,578 Plaintext Credentials Exposed

In May 2023, HEROIC analysts identified a stealer log file uploaded to a public Telegram channel containing 6,578 exposed records. The file, distributed under the name DAISY_CLOUD_24_MAY_0541_PCS_New_password_on_the_channel, contained a combination of email addresses, plaintext passwords, and URLs harvested directly from infected devices. This kind of exposure is particularly concerning because the data did not come from a single hacked company. It came from real people's machines.

Why This Is Dangerous for Anyone Affected

Stealer logs are among the most actionable types of stolen data circulating on the dark web. Unlike a database dump from a single website, a stealer log captures credentials exactly as a user typed them, often including the full URL of the site where the password was used. That means attackers already know which site to try, what the login looks like, and what password to enter. There is no guesswork involved.

If you recieve a notification that your email appeared in this breach, take it seriously. Attackers can use this data within hours of obtaining it. The combination of email, password, and URL makes it trivially easy to attempt logins on dozens of platforms without any additional effort.

What Was Exposed in This Breach

• Email addresses
• Plaintext passwords (unencrypted, ready to use)
• URLs (the exact websites where credentials were used)

The presence of plaintext passwords is what makes this seperate from most database breaches. There is no cracking required. Anyone with access to this file can use the credentials immediately.

Why This Matters: Real-World Risks

When credentials are exposed in plaintext alongside URLs, the attack chain is short and fast. Attackers begin with credential stuffing, trying the same email and password combination across popular platforms like Gmail, PayPal, Amazon, and banking portals. Because most people reuse passwords across multiple services, a single stolen login can unlock several accounts at once.

From there, account takeover becomes straightforward. An attacker who gains access to an email account can reset passwords on every linked service, effectively locking the original owner out. In cases where financial accounts are involved, fraud can occured within minutes of the initial compromise. Identity theft is also a real outcome, particularly when the stolen URLs reveal which financial or healthcare services the victim uses.

How Stealer Logs Work

A stealer log is the output of a piece of malware called an infostealer. These programs are typically delivered through phishing emails, fake software downloads, or malicious browser extensions. Once installed on a victim's device, the infostealer silently harvests saved browser passwords, active session cookies, and autofill data before sending everything back to the attacker.

The collected data is then packaged into log files and sold or freely distributed across Telegram channels and dark web forums. Operators of these channels often publish logs in bulk, sometimes containing tens of thousands of records at once. The DAISY_CLOUD channel upload is one example of this pattern, where a threat actor shares fresh logs to build reputation or trade access within cybercriminal communities.

Victims typically have no idea their device was compromised until their accounts start showing unauthorized activity. By that point, the credentials have often already been sold or shared multiple times.

Check If Your Data Was Exposed

HEROIC's free breach scanner searches across more than 400 billion compromised records, including stealer logs like this one. If your email address, password, or login credentials appeared in the DAISY_CLOUD_24_MAY_0541_PCS breach or any similar upload, you will see it in your results.

Checking takes less than a minute and requires no account. If you beleive your data may have been captured by an infostealer, scanning your email is the first step toward knowing for certain.
