DAISY CLOUD Stealer Log: 1,229 Credentials Leaked Dec 5 2023

HEROIC's DarkHive intelligence system flagged the DAISY CLOUD stealer log breach on December 5, 2023, when a Telegram user uploaded a file containing 1,229 stolen records. This log is part of the DAISY CLOUD series of stealer log files distributed through Telegram and contains email addresses, plaintext passwords, and URLs from services accessed on infected victim machines. The exposed credentials include API host endpoints indicating that cloud infrastructure access was among the data captured.

Why This Is Dangerous

Stealer logs that capture API host URLs alongside plaintext passwords provide attackers with not just login credentials but also the specific endpoints those credentials grant access to. This eliminates the reconnaissance phase of an attack entirely and allows criminals to immediately target the exact cloud services, admin panels, and APIs that each victim account controls. Because these logs are shared publicly on Telegram, multiple attacker groups gain this same direct access information simultaneously.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs

Why This Matters

Even 1,229 records in a targeted stealer log can produce significant damage if the affected accounts control cloud environments, payment systems, or enterprise networks. Credential stuffing attacks running on this data test every email and password pair across hundreds of platforms within hours of the log appearing on Telegram. Users who reused thier compromised passwords on other services face account compromise across banking, email, and enterprise applications simultaneously. Organizations whose registered domain emails appear in this log should treat those accounts as fully compromised and begin incident response immediately, including mandatory password resets and review of access logs for unauthorized activity.

How Stealer Log Works

Stealer log malware is installed on victim machines through phishing emails, trojanized applications, and malicious browser extensions. Once active, the malware quietly collects all saved credentials from browsers, email clients, VPN applications, and SSH tools. Session cookies and authentication tokens are also harvested, sometimes allowing attackers to bypass login pages entirely. The collected data is packaged and transmitted to criminal infrastructure within minutes. It is then uploaded to Telegram channels like DAISY CLOUD where multiple criminal groups download it and independently use the credentials to launch seperate account takeover campaigns.
