Our Analysts Found the Echo Cloud – Logs Dump Circulating in Private Channels

HEROIC analysts discovered the Echo Cloud - Logs - 15-02-2026 uploaded by a Telegram User dump while monitoring private Telegram channels used by threat actors to distribute stolen credentials. The breach exposed 2,236 records in February 2026, including email addresses, plaintext passwords, and URLs collected from compromised devices. This type of stealer log distribtion is becoming increasingly common as cybercriminals use messaging platforms to rapidly share and monetize stolen data.

Why Echo Cloud - Logs Is Dangerous

The Echo Cloud - Logs stealer breach is dangerous because it contains credentials captured in real time from infected machines. Plaintext passwords mean there is no encryption barrier protecting the victims. Attackers who download this file have everything they need to attempt logins on dozens of platforms simultaneously. The combination of email, password, and URLs tells attackers not just what accounts exist, but which specific services the victim uses, making targeted attacks far more efficent.

What Was Exposed in Echo Cloud - Logs

• Email Addresses
• Plaintext Passwords
• URLs (websites the victim visited or logged into)

Why This Matters

Credential stuffing attacks rely on logs exactly like this one. Criminals run automated tools that test each email and password combination against popular websites until they find a match. Once inside an account, they can lock out the real owner, steal personal information, initiate financial transfers, or use the compromised account to attack others. Identity theft and financial fraud are common outcomes when stealer log data reaches the wrong hands.

How Stealer Log Works

Stealer malware is usually delivered through fake software downloads, phishing emails, or malicious browser extensions. Once installed on a victim's device, it quietly collects saved passwords from browsers, active login sessions, and any credentials the user types. The malware packages this data into a log file and transmits it to the attacker. These logs are then sold on dark web marketplaces or shared freely in Telegram channels to maximize their reach among crimnal networks.
