Check If Your Email Is in the DAISY_CLOUD Stealer Log Leak

HEROIC analysts identified a stealer log file uploaded to a public Telegram channel on December 20, 2022. An anonymous Telegram user shared the file, which contained 6,436 records harvested from what appears to be a compromised endpoint connected to DAISY_CLOUD. The exposed data includes email addresses, plaintext passwords, and associated URLs, making this breach particularly dangerous for anyone whose credentials were captured.

Why This Is Dangerous

Stealer logs handed to anonymous actors on Telegram are weaponized fast. Because the passwords in this breach were stored in plaintext, an attacker does not need to crack anything. They can plug the emails and passwords directly into login forms across banking, email, and social media platforms within hours of obtaining the file. Even a single reused password can open the door to your most sensitive accounts.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (endpoint and API hosts)

Why This Matters

When email addresses pair with plaintext passwords, attackers gain an immediate toolkit for credential stuffing. They run automated scripts that test each email-password combination accross hundreds of popular websites simultaneously. Successful logins lead to account takeover, identity theft, and financial fraud. Victims often have no idea their account has been compramised until money goes missing or a stranger locks them out. The fact that this data was shared publicly on Telegram means it has likely been downloaded and used by multiple threat actors, multiplying the risk for everyone in the exposed list.

How Stealer Logs Work

A stealer log is created when malicious software, known as an infostealer, secretly runs on a device. The malware scans the infected machine for saved passwords, browser cookies, email credentials, and other sensitive data. It then packages everything into a log file and sends it back to the attacker. These log files are frequently sold or traded in underground markets and on platforms like Telegram. Because the malware collects data silently in the background, most victims have no idea their information was harvested until it surfaces in a breach report like this one. Infostealers often sneak onto devices through phishing emails, cracked software, or malicious browser extensions.
